An Observational Study on The Role of Magnetic Resonance Imaging in The Evaluation of Soft Tissue Tumors with Histopathological Correlation at Tertiary Care Centre

Background: The primary aim of this study is to evaluate the role of magnetic resonance imaging (MRI) in the assessment of soft tissue tumors with histopathological correlation at a tertiary care center. Methods: An observational study was conducted on 75 patients (n = 75) in the Department of Radiodiagnosis over 18 months. The targeted population comprised patients who presented to the Radiodiagnosis Department for radiological imaging of soft tissue tumors. Results: Out of 75 cases, 20% were found to have benign tumors, while 80% were found to have malignant tumors. The most frequent benign tumor was fibromatosis, with n = 10 cases (13.33%), and the most common malignant tumor was synovial sarcoma, with n = 14 cases (18.66%). The benign age group ranged from 11 to 20 years. T2-weighted heterogeneous hyperintensity was noted more frequently in malignant lesions, demonstrating a high positive predictive value; that is, 83% of malignant tumors exhibited changes on diffusion-weighted imaging/ apparent diffusion co efficient (DWI/ADC). Low-grade malignant lesions showed no restrictions. Most benign lesions displayed restrictions, with a high positive predictive value of 98.14%, specificity of 93.33%, and sensitivity of 88.33%. Conclusions: Soft tissue tumors can be detected and locally staged using MRI; thus, this technique has proven its value. Intralesional hemorrhage and calcification are two parameters that have been shown to have no substantial association with cancer. Due to its high sensitivity, MRI is a viable option for evaluating soft tissue tumors.

Free-hand ultrasound strain elastography in evaluation of soft tissue tumors.

The purpose of this study is to evaluate elastography in a wide spectrum of soft tissue superficial lesions by correlating the elastographic characteristics of these lesions with the elastographic score (ES) system established by Asteria. Forty patients with different superficial lesions of the soft tissues were studied, including lipomas, schwannomas, neuromas, epidermal inclusion cysts, "in transit" melanoma metastasis, arterio-venous malformation, and giant-cell tumor. An ultrasound examination was performed combined with color-Doppler and elastographic module. The B-mode criteria were echogenicity, margins, and structural homogeneity of the lesion. The color-Doppler criterion was irregular and mainly intra-nodular vascularization. ES 1-4 was attributed, in relation with the increasing tissue stiffness, according to the classification of Asteria adapted for soft tissues. Subsequently, we added to each single B-mode and color-Doppler criterion the ES 3 and 4, thus crossing two parameters of malignancy. All the presumptive diagnoses formulated were confirmed with the clinical data or with the histopathological result. The hypoechoic appearance had the best diagnostic performance. Sensitivity was 87%, specificity 71%, positive predictive value (PPV) 80%, negative predictive value (NPV) 80%, and diagnostic accuracy 80%. There was a good correlation with the clinical and biopsy data, the irregularity of margins the worst performance, the inhomogeneity an intermediate. Color-Doppler had sensitivity 74%, specificity 82%, PPV 85%, NPV 70% and diagnostic accuracy 77.5%. Elastography had sensitivity 87%, specificity 94%, PPV 95%, NPV 84%, and diagnostic accuracy 90%. The combination hypoechoic appearance + ES3/ES4 showed sensitivity 83%, specificity 100%, PPV 100%, NPV 81%,and diagnostic accuracy of 90%. The combination of irregularity of margins + ES3/ES4 showed sensitivity 43%, specificity 100%, PPV 100%, NPV 59%, and diagnostic accuracy of 67.5%. The combination of inhomogeneity of the lesion + ES3/ES4 showed sensitivity 65%, specificity 94%, PPV 94%, NPV 68%, and diagnostic accuracy of 78%. The combination of the color-Doppler with the ES3/ES4 showed sensitivity 69.5%, specificity 100%, PPV 100%, NPV 71%, and diagnostic accuracy of 82.5%.In the combined evaluation, there was a significant increase in specificity, allowing healthy subjects to be categorized as correctly negative, with a reduction in false positives which also translates into an increase in PPV. Elastography alone is not sufficient for a correct diagnostic classification and must be considered as an additional parameter in the study of soft-tissue lesions. Although there was a good agreement between B-mode malignancy criteria and ES3/ES4, there is no significant improvement in sensitivity. Ultrasound assessment, especially of superficial lesions, cannot be separated from an integrated approach that foresees the additional and routine use of the elastographic examination.

Cytomorphology of mesenchymal lesions in a tertiary care centre and its correlation with histopathology.

Fine needle aspiration cytology (FNAC) is a minimally invasive method for sampling a heterogenous lesion. It is one of the first-line investigations in the evaluation of soft tissue tumours. However, the heterogeneity of mesenchymal lesions pose a challenge to the cytological diagnosis. The present study aims at evaluation of the cytomorphological findings of mesenchymal lesions on FNAC along with their histopathological correlation. This was a retrospective study conducted over a period of 1 year from January 2021 to January 2022. All the patients of cytologically diagnosed mesenchymal lesions on their FNA aspirates were included in the study. Cytomorphology of the May Grunwald Giemsa and Papanicolaou stained slides were examined and correlated with clinical and histopathological details wherever available. Out of the 90 patients, 69 (76.7%) were males and 21 (23.3%) were females. Maximum number of cases were in 4-5th decade of life. The lower limb was found to be the most common site (57.8%) for the mesenchymal lesions. Majority of the cases on FNA in our study were found to be benign - 79 (87.8%), while only 11 cases were malignant (12.2%). On cytological examination, spindle cell lesions were most common followed by adipocytic lesions. Based on the cyto-histological correlation, sensitivity, specificity, negative predictive value, positive predictive value and diagnostic accuracy of FNAC in diagnosis of mesenchymal lesion was 78.6%, 100%, 92.5%, 100% and 94.1% respectively. FNAC is a simple and minimally invasive tool that plays an important role in triaging patients with good specificity and sensitivity.

MRI Evaluation of Soft Tissue Tumors and Tumor-Like Lesions of Extremities.

The current study aimed to evaluate the use of magnetic resonance imaging (MRI) in the diagnosis of extremity soft tissue tumors and tumor-like abnormalities. This prospective observational study of 71 patients with soft tissue lesionsof extremities was conducted at a tertiary hospital and teaching center in western India after obtaining Institutional Ethical Committee (IEC) clearance. All patients underwent an MRI of the region of interest on Siemens Magnetom Vida 3 Tesla MRI (Erlangen, Germany). MRI findings and diagnosis were correlated clinically and with histopathological examination. A total of 71 patients (49 males and 22 females) in the age group of six to 90 years were included in our study. Out of 44 patients with soft tissue tumors, the most common lesion was neurofibroma (18.1%), followed by lipoma and undifferentiatedsarcoma (9.1% each). Liposarcoma, myxoid liposarcoma, giant cell tumor of the tendon, pigmented villonodular synovitis, and schwannoma were seen in 4.5% of patients each. The soft tissue tumor-like lesions were seen in 27 (38%) patients, the most common being slow-flow vascular malformation, which was seen in 9/27 (33%) patients. The second most common pathology was actinomycosis, seen in four (14.8%) patients. Out of 44 patients with soft tissue tumors, 27 (61.4%) were benign and 17 (38.6%) were malignant.Tumor size of more than 5 cm was more commonly seen in malignant tumors (70.5%) than benign tumors (40.7%). The smooth margin was more common in benign tumors (70.3), while most malignant tumors (70.5%) had irregular or lobulated margins.Heterogenous enhancement was more common in malignant tumors (82.3%) than benign tumors (62.9). The odds of a benign histopathological diagnosis for a tumor suspected to be benign by MRI were 93.75 times higher than the odds of a benign histopathological diagnosis for a tumor suspected to be malignant by MRI. MRI is extremely useful in the evaluation of different soft tissue masses and helps in evaluating the characteristics of the masses, their extent and relationship to surrounding structures, and bone destruction, multiplicity, composition, and enhancement pattern. The systematic imaging analysis approach helps to differentiate a benign lesion from a malignant lesion and also in differentiating various soft tissue tumor mimics.

Presurgical Perspective and Posttreatment Evaluation of Soft Tissue Tumors of the Ankle and Foot in Adults.

This article discusses soft tissue tumors of the ankle and foot region in adults, including tumors of the joints, and also briefly addresses tumor-simulating lesions. We offer general recommendations and describe specific aspects of common entities in that region, such as typical imaging appearance, therapeutic strategies, and posttherapeutic considerations. Focal masses and diffuse swelling are common in the foot and ankle region; most of them are non-neoplastic. Some of the tumors, such as plantar fibromatosis, tenosynovial giant cell tumor, synovial chondromatosis, or schwannoma, have a very typical appearance on magnetic resonance imaging. Sarcomas are rare among true soft tissue tumors; however, they can be small and well demarcated, may grow slowly, and are often misinterpreted as benign. This is especially true for synovial sarcoma, one of the most common sarcomas in this region. Densely packed tissues in the foot and ankle may hamper determining the tissue of origin. Adherence to diagnostic guidelines and cooperation with tumor centers is crucial including for posttherapeutic surveillance. We also describe typical posttherapeutic changes and complications after surgery, radiation therapy, and chemotherapy, as well as parameters for the detection and exclusion of recurrence of soft tissue tumors of the ankle and foot.

MRI evaluation of soft tissue tumors: comparison of a fast, isotropic, 3D T2-weighted fat-saturated sequence with a conventional 2D T2-weighted fat-saturated sequence for tumor characteristics, resolution, and acquisition time.

To test whether a 4-fold accelerated 3D T2-weighted (T2) CAIPIRINHA SPACE TSE sequence with isotropic voxel size is equivalent to conventional 2DT2 TSE for the evaluation of intrinsic and perilesional soft tissue tumors (STT) characteristics. For 108 patients with histologically-proven STTs, MRI, including 3DT2 (CAIPIRINHA SPACE TSE) and 2DT2 (TSE) sequences, was performed. Two radiologists evaluated each sequence for quality (diagnostic, non-diagnostic), tumor characteristics (heterogeneity, signal intensity, margin), and the presence or absence of cortical involvement, marrow edema, and perilesional edema (PLE); tumor size and PLE extent were measured. Signal-to-noise (SNR) and contrast-to-noise (CNR) ratios and acquisition times for 2DT2 in two planes and 3DT2 sequences were reported. Descriptive statistics and inter-method agreement were reported. Image quality was diagnostic for all sequences (100% [108/108]). No difference was observed between 3DT2 and 2DT2 tumor characteristics (p < 0.05). There was no difference in mean tumor size (3DT2: 2.9 ± 2.5 cm, 2DT2: 2.8 ± 2.6 cm, p = 0.4) or PLE extent (3DT2:0.5 ± 1.2 cm, 2DT2:0.5 ± 1.0 cm, p = 0.9) between the sequences. There was no difference in the SNR of tumors, marrow, and fat between the sequences, whereas the SNR of muscle was higher (p < 0.05) on 3DT2 than 2DT2. CNR measures on 3DT2 were similar to 2DT2 (p > 0.1). The average acquisition time was shorter for 3DT2 compared with 2DT2 (343 ± 127 s vs 475 ± 162 s, respectively). Isotropic 3DT2 MRI offers higher spatial resolution, faster acquisition times, and equivalent assessments of STT characteristics compared to conventional 2DT2 MRI in two planes. 3DT2 is interchangeable with a 2DT2 sequence in tumor protocols. • Isotropic 3DT2 CAIPIRINHA SPACE TSE offers higher spatial resolution than 2DT2 TSE and is equivalent to 2DT2 TSE for assessments of soft tissue tumor intrinsic and perilesional characteristics. • Multiplanar reformats of 3DT2 CAIPIRINHA SPACE TSE can substitute for 2DT2 TSE acquired in multiple planes, thereby reducing the acquisition time of MRI tumor protocols. • 3DT2 CAIPIRINHA SPACE TSE and 2DT2 TSE had similar CNR of tissues.

Diagnostic Performance of Dynamic Contrast-Enhanced MRI and 18F-FDG PET/CT for Evaluation of Soft Tissue Tumors and Correlation with Pathology Parameters

To assess the diagnostic performance of dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) and fluorine-18-fluorodeoxyglucose (18F-FDG) positron-emission tomography/computed tomography (PET/CT) parameters in evaluating the biological behavior of soft tissue tumors. We retrospectively analyzed DCE-MRI and 18F-FDG PET/CT parameters in 78 patients with pathology-confirmed soft tissue tumors. A total of 78 patients had undergone DCE-MRI examination, while 24 patients with malignant soft tissue tumor had undergone 18F-FDG PET/CT examination. Microvessel density (MVD) and the Ki-67 labeling index (LI) were detected using immunohistochemistry. Differences in parameters (Ktrans, Kep, Ve, MVD, and Ki-67 LI) between benign and malignant tumors were compared. Differences in parameters (Ktrans, Kep, Ve, MVD, and SUVmax) between high- and low-proliferation malignant tumors (grouped by Ki-67 LI) were compared. Correlation of the DCE-MRI and 18F-FDG PET/CT parameters with MVD and Ki-67 LI was analyzed. Only the Ktrans, Kep, MVD, and Ki-67 LI differed significantly between the benign and malignant soft tissue tumors (all p < 0.001). Only Kep (p=0.033) and SUVmax (p=0.001) differed significantly between high- and low-proliferation malignant soft tissue tumors. Ktrans, Kep, and SUVmax correlated positively with MVD (r=0.805, 0.778, 0.730, respectively; all p < 0.001), and with Ki-67 LI (r=0.721, 0.685, 0.655, respectively; all p < 0.001). DCE-MRI and 18F-FDG PET/CT parameters indicate soft tissue tumor biological behavior and can be used to differentiate between benign and malignant soft tissue tumors and between high- and low-proliferation malignant soft tissue tumors.

RADIOLOGICAL EVALUATION OF SOFT TISSUE MASSES WITH CLINICO-PATHOLOGICAL CORRELATION

Evaluation of soft tissue tumours has undergone a dramatic change with the advent of ultrasonography(USG),magnetic resonance(MR)imaging and computed tomography (CT). Patients are referred for imaging to evaluate a soft tissue lesions in the trunk or extremities.These lesions range from non-neoplastic conditions to benign and malignant tumours. The primary goal for the imaging referral is to confirm the presence of a mass and to assess its extent. And also the study is an attempt to define the role of different imaging modalities in the evaluation of patients with soft tissue tumours in correlation with histopathology.

Histocytopathological Evaluation of Soft Tissue Tumours: A Retrospective Study

Introduction: Soft Tissue Tumours (STTs) are a heterogeneous group of lesions arising from non-epithelial extraskeletal tissue of the body. The use of Fine Needle Aspiration Cytology (FNAC) in the evaluation of STTs is debatable because of their extremely varied morphology. Aim: To assess the efficacy of FNAC in the diagnosis of STTs as a routine procedure. Materials and Methods: The present study was a retrospective study conducted at VSS Institute of Medical Science and Research, Burla, Sambalpur, Odisha, India, from December 2016 to November 2018. A total of 186 cases of STT were correlated with histopathological studies. Fine needle aspirate air-dried smears were stained with Diff-Quik and 95% alcohol fixed smears were stained with Papanicolaou (PAP) stain. Corresponding histopathological sections were stained with Haematoxylin and Eosin (H&amp;E) stain. Immunostaining was performed as and when required to confirm histological diagnosis. Results were analysed using International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) Statistics 22.0. Results: Out of 186 cases, 162 (87.09%) were diagnosed as benign and 24 (12.91%) as malignant. Three false negative and two false positive cases were reported. The sensitivity, specificity, Positive Predictive Values (PPV), Negative Predictive Values (NPV) and overall diagnostic accuracy were 87.5%, 98.7%, 91.3%, 98.1% and 97.3%, respectively. There was statistically significant difference between the cytological diagnosis and the final histological diagnosis (χ2=35.5, p&lt;0.05). Conclusion: Fine Needle Aspiration (FNA) is very important for initial diagnostic work-up, while histopathology with the help of immunostain provides a final diagnosis.

FNAC helps in the initial management of soft tissue tumours as it is rapid and fairly accurate. Keywords: Soft issue tumours, Cytology, Patterns, Histopathology.

Functional imaging in soft tissue sarcomas: Update of the indications for 18F-FDG-PET/CT

Soft tissue sarcomas (STS) are a rare and heterogeneous group of tumors. They account for 1% of solid malignant tumors in adults and 7% in children and are responsible for 2% of cancer mortality. They require a multidisciplinary approach in centers with experience. This collaboration aims to update the scientific evidence to strengthen, together with clinical experience, the bases for the use and limitations of 18F-FDG-PET/CT in STSs. The general recommendations for the use of PET/CT in STS at present are summarized as the initial evaluation of soft tissue tumors when conventional image does not establish benignity with certainty and this determines the approach, in biopsy guiding in selected cases, in the initial staging, as additional tool, for rhabdomyosarcoma and STS of extremities or superficial trunk and head and neck tumors, in the suspicion of local recurrence when the CT or MRI are inconclusive and in the presence of osteosynthesis or prosthetic material and in assessment of therapy response to local/systemic therapy in stages ii/iii. In addition, PET/CT has the added value of being a surrogate marker of the histopathological response and it provides prognostic information, both in the baseline study and after treatment.

Advanced magnetic resonance imaging (MRI) of soft tissue tumors: techniques and applications.

Imaging evaluation of soft tissue tumors is important for the diagnosis, staging, and follow-up. Magnetic resonance imaging (MRI) is the preferred imaging modality due to its multiplanarity and optimal tissue contrast resolution. However, standard morphological sequences are often not sufficient to characterize the exact nature of the lesion, addressing the patient to an invasive bioptic examination for the definitive diagnosis. The recent technological advances with the development of functional MRI modalities such as diffusion-weighted imaging, dynamic contrast-enhanced perfusion imaging, magnetic resonance spectroscopy, and diffusion tensor imaging with tractography have implemented the multiparametricity of MR to evaluate in a noninvasive manner the biochemical, structural, and metabolic features of tumor tissues. The purpose of this article is to review the state of the art of these advanced MRI techniques, with focus on their technique and clinical application.

Big Foot MRI: A Practical Guide for Radiologists to Soft Tissue Tumors and Tumor-Like Lesions of the Foot

ABSTRACT The foot is a relatively rare site of soft tissue neoplasm, and tumors at this site offer unique diagnostic challenges. MRI is the modality of choice for the evaluation of soft tissue tumors of the foot, related to its intrinsic high soft-tissue contrast and multiplanar capability. This article reviews the MRI appearance of the common soft tissue masses in the foot together with their clinical, radiographic, and pathological features. Even though there is a large overlap between benign and malignant lesions in the foot, MRI characteristics can be useful to provide a practical guide for radiologists to establish a focused differential diagnosis.

Diffusion weighted MRI of soft tissue masses: Can measurement of ADC value help in the differentiation between benign and malignant lesions?

ObjectiveTo assess the ability of DWI & numerical ADC values associated with routine MRI in classification of different musculoskeletal soft tissue masses. Patient & method45 patients (32 females and 13 males) with known or clinically suspected to have musculoskeletal soft tissue masses were included. Their age ranging from (9–72) years, they all subjected to conventional MRI, DWI and ADC values were calculated, The diagnosis was confirmed by histologic biopsy. ResultsBenign neoplasms (except for lipomas) showed values of ADC above 1.275 × 10−3 mm2/s while malignant soft tissue tumors (except for high-grade myxofibrosarcoma) have ADC values below 1.1 × 10−3 mm2/s. Mean ADC values for benign and malignant soft tissue tumors were 1.53 ± 0.91 mm2/s and 0.84 ± 0.33 mm2/s respectively with cutoff value 1.235 mm2/s showing sensitivity, specificity & accuracy 73%, 91.7% & 80.3% respectively. Tru cut biopsy done in (28) patients (8 benign & 20 malignant masses), frozen sections confirmed diagnosis of other 10 benign masses and reconfirmed diagnosis of the previously biopsied 20 malignant masses, the last 7 patients couldn't be biopsied & were diagnosed from patient medical profile at our institute. ConclusionAddition of DWI &quantitative ADC mapping to routine MR examination is advised for evaluation of soft tissue tumors especially in the inconclusive cases.

Magnetic Resonance Imaging Assessment of Soft Tissue Tumours

Abstract Introduction. Due to the non-specific clinical findings and the reduced sensitivity of conventional radiography, soft tissue tumors (STT) were virtually unknown to radiologists until ultrasonography and computerized tomography were introduced. Because of its superior soft tissue contrast, multiplanar imaging capability, Magnetic Resonance Imaging (MRI) is the favored modality for the evaluation of soft tissue tumors. Purpose. MRI detection, characterization, and illustration of soft tissue tumors developed in the musculoskeletal system Material and method. The retrospective study refers to a group of 77 patients with suggestive clinical symptomatology for a soft-expanding process developed in the musculoskeletal system. Patients were examined according to a protocol that included complete clinical examination, two incidents radiographic examination, MRI, histopathological examination. The group consisted of 44 men (57%) and 33 (43%) women, aged between 7 and 80. Results. We presented the spectrum of identified types of tumors based on the MRI semiology elements (homogeneity and intensity of the signal in the native and post-contrast standard sequences, intra or extra compartmental localization, tumor size and shape), segmental location, and incidence relative to the histological type. Conclusions. Through high contrast resolution and the ability to acquire and display multiplanar, MRI is currently investigating choice in the detection and characterization of soft tumor tumors. The multiplanar images (axial, frontal, sagittal and oblique) provide complete data on the actual tumor extension, the appearance of vessels, nerves, bone segments, and adjacent joints to tumor formations, allowing the proper staging and appropriate therapeutic behavior.
