Metastatic bilateral adrenal sarcomatoid carcinoma: Evaluation by F-FDG PET/CT.

Sarcomatoid carcinoma of the adrenal gland is an uncommon presentation of malignant adrenal tumors and bilateral presentation is extremely rare. It is an extremely rare occurrence, unusual symptoms, and both epithelioid and sarcomatoid components in histology are a challenge to diagnose sarcomatoid carcinoma of adrenal origin. The majority of patients are diagnosed at a later stage while having metastatic disease and succumb due to disease within a few months of diagnosis due to the aggressive nature of the disease.

Fluorodeoxyglucose PET/Computed Tomography in Evaluation of Prosthetic Joints and Diabetic Foot: A Comparative Perspective with Other Functional Imaging Modalities.

Infection imaging has been an important part of nuclear medicine practice. Infections in prosthetic joints and diabetic foot are associated with devastating complications, posing substantial challenge for both diagnosis and overall management. For many years, conventional nuclear medicine techniques have been used to frame a painful joint arthroplasty or diabetic foot infection.

F-FDG PET/CT in the Evaluation of Solitary Extramedullary Plasmacytoma: A Case Series.

The role of fluorine-18-fluorodeoxyglucose positron emission tomography/ computed tomography (F-FDG PET/CT) in patients with multiple myeloma (MM) and other plasma cell disorders is well-known. Solitary plasmacytoma (SP), an extremely rare form within this entity accounting for approximately 4% of plasma cell malignancies, can be classified as solitary bone plasmacytoma (SBP) or solitary extramedullary plasmacytoma (SEMP). Extramedullary plasmacytoma (EMP) is a rare neoplasm characterized by the monoclonal proliferation of plasma cells outside the bone marrow.

Late Manifestation of Struma Peritonei and Widespread Functioning Lesions in the Setting of Struma Ovarii Simulating Highly Differentiated Follicular Carcinoma.

Malignant transformation of struma ovarii is a rare event observed in about 5% of cases. We present here an unusual case that closely simulated highly differentiated follicular carcinoma, an entity with a relatively similar appearance to malignant struma ovarii. In our case, peritoneal and systemic dissemination occurred 18 y after excision of struma ovarii, which had been reported as histopathologically benign.

[¹³¹I]Metaiodobenzylguanidine therapy in neural crest tumors: varying outcome in different histopathologies.

Aim: To evaluate the response of [¹³¹I] metaiodobenzylguanidine ([¹³¹I]MIBG) therapy in patients with neuroectodermal tumors and to assess their quality of life using the functional assessment of cancer therapy - general quality-of-life questionnaire for patients who are on follow-up after MIBG therapy.

Materials And Methods: Thirty-two patients diagnosed with various subtypes of neuroectodermal tumors and treated with [¹³¹I]MIBG were included in this retrospective analysis. Response to therapy was evaluated objectively by comparing pretherapy and posttherapy biochemical markers, radiological investigations, and follow-up MIBG scans.
