Rare cause of obliteration of the cardiophrenic angle

The differential diagnosis of mediastinal masses encompasses a vast spectrum ranging from benign tumors to notorious malignancies. Mediastinal lipoma is a very rarely encountered mediastinal mass. It is usually an incidentally unearthed finding. It has a classical radiographic countenance. Knowledge of its existence and presentation aids early diagnosis and can avert unnecessary invasive investigations for alternative diagnosis. The radiographic picture of cardiophrenic obliteration may be seen in a number of heterogeneous conditions such as loculated pleural effusion, pericardial effusion, diaphragmatic hernias, or in certain mediastinal masses. However, mediastinal masses are rarely kept as a differential of this radiological presentation due to a lack of awareness. This leads to performance of invasive tests like thoracocentesis. We herein report an interesting case of mediastinal lipoma incidentally picked up during a chest radiograph done as a part of preoperative evaluation for an unrelated diagnosis. The chest radiograph exhibited a lesion with an obliteration of the right cardiophrenic angle.

Avoiding invasive surgical procedures for a slow-growing asymptomatic huge anterior mediastinal lipoma under watchful waiting.

A mass shadow in the right lower lung field was detected by chest X‐ray in a 79‐year‐old woman, which was eventually diagnosed as anterior mediastinal lipoma. She remained under watchful waiting without surgery for 9 years without developing symptoms, even though the lipoma had grown to an extremely large size.

SURGICAL TACTICS TO GIANT LIPOMAS OF THE MEDIASTINUM(OBSERVED IN PRACTICE)

Lipoma of the mediastinum accounts for 1.6–2.3% of the primary formed mediastinal lumps.The size of this neoplasmless than 5 cm in 80% of cases and more than 10 cm in less than 1% of cases. Mediastinal lipomas are more common than subcutaneous lipomas.In a patient who applied to the Department of Thoracic and Vascular Surgery of the Bukhara Regional Multidisciplinary Medical Center, the chest was divided into thin soft tissue barriers with a clear border on the thoracic cavity in the Multislice CTexamination. fat tissue density -95 -118 HU, dimensions 29.8x25.6x14.9 cm, a giant neoplasmoccupying the lungs was identified

Resection of a huge mediastinal well-differentiated liposarcoma involving left thoracic cavity

BackgroundMediastinal lipoma/liposarcoma is a rare tumor of the mediastinum.Case presentationThis article reported one case of giant anterior superior mediastinum well-differentiated liposarcoma involving the left thoracic cavity with symptom of dysphagia. The mediastinum liposarcoma was completely resected through a left thoracotomy. Histologic examination and molecular pathological test clarified the diagnosis as well-differentiated mediastinal liposarcoma. There has been no evidence of recurrence during the 8 months follow-up.ConclusionMolecular pathological examination of the MDM2, CDK4 and p16 gene in tumors provides the diagnostic gold standard in distinguishing well-differentiated liposarcoma from lipoma. Complete surgical resection is the first-line treatment choice for mediastinal lipoma/ liposarcoma.

A Rare Tumor of Mediastinum in A Child; Giant Mediastinal Lipom

Lipomas are benign mesenchymal tumors originating from fat tissue. Mediastinal lipomas are very rare, constitute 1.6% - 2.3% of all primary mediastinal tumors and most commonly located at anterior mediastinum. It is often asymptomatic and is detected incidentally on radiographs taken. The symptoms that it creates caused by the pressure it has on the surrounding organs. If it is asymptomatic, follow-up is sufficient, but complete excision is needed for the symptomatic cases. This report presents the imaging findings of a giant lipoma of the anterior mediastinum that was detected incidentally and followed up on asymptomatically for 3 years.

Co-Existent Symptomatic Large Retrosternal Nontoxic Multinodular Goiter With Mediastinal Lipoma

ABSTRACT Objective: To present a rare case of a co-existing large retrosternal nontoxic multinodular goiter (MNG) and a large mediastinal lipoma in a woman with compressive symptoms. Methods: The clinical presentation and diagnostic utilization of computed tomography (CT) in the management of this case are presented. Results: A 66-year-old woman was evaluated for slowly progressive, intermittent dysphagia and neck pressure over a period of 4 years. The nodular thyroid gland had been biopsied in the past and noted to be benign. Examination of the thyroid showed a large nodular goiter with an estimated weight in excess of 100 g. Thyroid function tests were within normal limits. A chest radiograph showed a large soft tissue mass in the upper right anterior mediastinum and lower neck with displacement of the trachea to the left. A CT scan with intravenous contrast of the neck and chest showed that the mass was comprised of both a large MNG and a large adjacent fat density mass in the right anterior mediastinu...

Recurrent Mediastinal Lipoma: A Case Report

Mediastinal lipoma (ML) is a rare entity. Though the mediastinum is the most common site of intrathoracic lipoma, ML constitutes less than 1% of all mediastinal tumours. ML frequently presents on incidental radiographic finding, CT scan is considered the investigation of choice. CT features of lipoma are quite characteristic. They are clinically significant because: (1) Despite their benign nature, these tumours tend to reach an enormous size and can cause compression of lungs and mediastinal structures; (2) It may not always be possible to differentiate a ML from a liposarcoma by CT or MRI alone.

Growing Peripheral Pulmonary Lipoma: A Case Report

Intrathoracic lipomas can be divided into five categories, depending on their location: endobronchial lipomas, pulmonary parenchymal lipomas, pleural lipomas, mediastinal lipomas, and cardiac lipomas (1). Among them, endobronchial lipomas are relatively common, while pulmonary parenchymal lipomas are extremely rare (2). In a differential diagnosis of solitary pulmonary lesions, pulmonary parenchymal lipomas should be considered, despite their rarity.

Is this a mediastinal tumor? A case of Morgagni hernia complicated with intestinal incarceration mistaken for the mediastinal lipoma previously

INTRODUCTIONMorgagni's hernia is a congenital herniation of abdominal viscera into the thoracic cavity through a retrosternal diaphragmatic defect. PRESENTATION OF CASEWe present a case of incarcerated Morgagni hernia in a 69-year-old woman. Three years previously, she had undertaken a video-assisted thoracoscopic resection (VATS) of a mediastinal mass, which had been mistaken for a lipoma. Following the primary repair of the hernia at emergency laparotomy, the patient was discharged home uneventfully. DISCUSSIONIrrespective of the radiologically characteristic findings of our case, the possibility of Morgagni hernia had not been entertained at the first operation. Thorough exploration around the diaphragm at the first VATS operation could have revealed the Morgagni hernia, ultimately avoiding the hernia-related complication such as an incarceration. CONCLUSIONMorgagni hernia as a differential diagnosis in case of anterior mediastinal mass should not be missed.

A rare case of dysphagia and palpitation caused by the compression exerted by an enormous mediastinal lipoma

A 65-year-old woman presented with mild dysphagia, weight loss and intermittent palpitation. Chest radiograph revealed a large opacity in the right lower lung field. Subsequent CT scan showed a large posterior mediastinal lipoma extending from the level of the aortic arch to the thoracoabdominal junction. After thoracoscopic resection, the patient's dysphagia and palpitation were resolved. After a follow-up of 2 years, the patient has had no evidence of recurrence.

Hernia of Morgagni and Mediastinal Lipoma: A Case Report

A hernia of Morgagni (also called hernia of Morgagni-Larrey) is a congenital herniation of abdominal contents into the thoracic cavity through a retrosternal diaphragmatic defect. The Morgagni hernia can create uncertainty in its diagnosis and difficulty for subsequent treatment. If after clinical examination and x-ray we suspect the hernia, computed tomography imaging should be the desired imaging method to confirm the diagnosis. Surgery is the only definitive treatment. When a patient presents signs and symptoms of incarceration or strangulation, emergency surgery is required. We report the first life-threatening case of an association between a hernia of Morgagni and a mediastinal lipoma. We present an adult patient with mediastinal lipoma and a right incarcerated hernia of Morgagni with engagement of the stomach, the duodenum and the transverse colon, successfully treated without complications. To our knowledge, this is the first report of an association between those two rare entities in an acute setting. We discuss the differential diagnosis and physiopathology of the condition, referring to published reports.

Complete removal of heart-compressing large mediastinal lipoma : a case report

An 83-year-old man presented with worsening of respiratory discomfort and underwent close examination, which revealed a large mediastinal lipoma measuring 15 × 10 cm. The patient showed heart failure symptoms due to heart compression by tumor. The tumor was completely removed safely and reliably by cutting the ascending aorta, main pulmonary artery and superior vena cava. Although preoperative examination could not determine whether the tumor was lipoma or liposarcoma, we selected an invasive surgical therapy because neither radiation therapy nor chemotherapy was considered effective for either type of tumor. We report here a very rare case of heart-compressing mediastinal tumor.

A rare association of serous cystadenoma of the pancreas with mediastinal lipoma: a case report

Cystic lesions of pancreas include a myriad of different conditions ranging from the common pseudocyst to unusual cystic neoplasm. With the development of better imaging modalities, cystic neoplasms are diagnosed with greater frequency and accuracy leading on to better understanding of the natural course of these lesions. Serous cystadenoma is one of the rare neoplasms of the pancreas that is unique for its benign nature. Most of the time surgery is indicated for the symptom of pain when the lesion enlarges. Surgery may also be indicated due to the fact that, it may not always be possible to dogmatically differentiate it from the potentially malignant counterpart radiologically. One of the interesting aspects about serous cystadenoma is its association with other systemic disorders like von Hippel Lindau syndrome. Herein we report a rare association of serous cystadenoma with mediastinal lipoma, which has not been reported in the literature.

Cardiac herniation through mediastinotomy incision

A 43-year-old man was admitted to the emergency department after a cardiac arrest of unknown etiology. The patient's medical history was unremarkable except for surgery to remove a mediastinal lipoma two years earlier. In the intensive care unit, he was observed to have a mass bulging from the left chest wall. Echocardiography showed cardiac herniation through the chest wall, which was confirmed by thoracic computed tomographic scan.

Intrathoracic omental herniation through the esophageal hiatus in a young patient

We herein present a case of intrathoracic omental herniation through the esophageal hiatus in a young patient. A 21-year-old obese man was asymptomatic, and his chest X-ray demonstrated a large, sharply defined mass. A computed tomography scan of the thorax indicated a large retrocardial mediastinal mass in which the density indicated the presence of fatty tissue judging from the Hounsfield unit range. A thoracotomy was performed under a diagnosis of either mediastinal lipoma or liposarcoma with an encapsulated fatty mass, measuring 17 x 12 x 8 cm in size. The mass, however, proved to be an omental herniation through the esophageal hiatus. It is generally assumed that the major contributing factors leading an individual to develop an omental herniation through the esophageal hiatus include aging and obesity. This is the first report of omental herniation through the esophageal hiatus in a patient still in his twenties.

Mediastinal Lipoma: A Case Report

Mediastinal lipoma[ML] is a rare entity. Though the mediastinum is the most common site of intrathoracic lipoma1, ML constitute less than 1% of all mediastinal tumors2. ML frequently represent an incidental roentgenographic finding. CT Scan is considered the investigation of choice3. CT features of lipoma are quite characteristic. They are clinically significant because ;1] Despite their benign nature, these tumors tend to reach an enormous size and can cause compression on lungs and mediastinal structures and 2] It may not always be possible to differentiate a ML from a liposarcoma on CT or MRI alone4.

A CASE OF THYMOLIPOMA

A 58-year-old woman was admitted to the hospital because of an abnormal shadow on chest X-ray, film, which was pointed out at a medical checkup, though she had no complaint. CT scan revealed a tumor corresponding to fat CT value at the anterior mediastinal region, and an operation was performed under a diagnosis of mediastinal lipoma. The resected specimen weighed 340g without surrounding infiltration. Pathological examination showed that the tumor was thymic lipoma. Thirty-six cases of thymic lipoma have been reported in Japan so far. There were 13 males and 23 female, with an averaged age of 36.6 years. This disease was often asymptomatic and commonly detected at medical checkup. Five patients were complicated by Myasthenia gravis. In the diagnosis of this disease CT scan is useful. Recently this disease has been increasingly seen in the literature and been considered not so rare as before. A recent widespread use of CT may contribute to this tendency.
