CT Evaluation of Neoplasms in the Temporal Region

Abstract

Background: Temporal bone imaging has always been a challenge. Though infections and trauma are the most common pathologies encountered; a wide range of neoplasms affect this region which can become a serious threat if overlooked. Computed Tomography (CT) plays a crucial role in diagnosis and characterization of these neoplasms. It is very helpful to evaluate the extent of the lesion and involvement of adjacent structures, helping to decide appropriate management. Aims and Objectives: The purpose of our study was primarily to evaluate various neoplasms in the temporal region based on CT findings in patients presenting to the radiology department in a tertiary care centre. Materials and Methods: The prospective study done over a period of 2 years in the Department of Radio-diagnosis at Dr. Vasantrao Pawar Medical College, Hospital and Research Centre, Nashik included 26 patients with neoplasms involving the temporal region. CT scan of all these patients was performed on Siemens Somatom Perspective (128 slice). The imaging findings were correlated with histopathological and surgical findings wherever available. Results: The study comprised of 26 patients in which bulk of the patient's i.e. 42% had features of vestibular schwannoma on imaging. Glomus tumour and cerebellopontine angle epidermoid cyst found in 15% and 11% of patients, respectively were the other common lesions. Neoplasms were most common in the age group of 41 to 50 years. There was female preponderance (62%) amongst patients. Headache and hearing loss were the most common complaint. Conclusion: We can ascertain from this study that neoplasms in the temporal region show characteristic findings on CT imaging. These imaging characteristics coupled with other imaging and clinical findings help us to achieve an accurate diagnosis. Imaging techniques enables a reliable non-invasive assessment of these neoplasms.
