Bilateral adrenal abnormalities: imaging review of different entities.

Bilateral adrenal abnormalities are not infrequently encountered during routine daily radiology practice. The differential diagnoses of bilateral adrenal abnormalities include neoplastic and non-neoplastic entities. The bilateral adrenal tumors include metastasis, lymphoma, neuroblastoma, pheochromocytoma, adenoma, and myelolipoma.

Erdheim-Chester Disease with No Skeletal Bone Involvement and Massive Weight Loss.

Erdheim-Chester disease (ECD) is a rare type of non-Langerhans cell histiocytosis, with only 550 cases reported worldwide. ECD is characterized by diffuse histiocytic infiltration of multiorgans. The age of presentation of this disease is typically between 40 and 70 years.

99mTc-DMSA Uptake in a Sister Mary Joseph's Nodule From Ovarian Cancer.

A 50-year-old woman with ovarian cancer underwent Tc-DMSA scan to evaluate the functional status of the right hydronephrotic kidney. The images incidentally revealed a well-defined focus of mild radiotracer uptake at the midanterior abdominal wall, which correlated with a metastatic Sister Mary Joseph's nodule seen on CT performed a week earlier.

Clinical Presentation, Risk Factors, and Treatment Modalities of Hepatocellular Carcinoma: A Single Tertiary Care Center Experience.

Objective. To investigate the risk factors, clinical characteristics, treatment modalities, and outcomes in Saudi patients with HCC and propose points for early detection of the disease. Methods.

Neuroendocrine tumor of the appendix inside an incarcerated Amyand's hernia.

Amyand's hernia is a rare type of hernia where the vermiform appendix is within an inguinal hernia sac. Tumors of the appendix are quite uncommon. The coincidence of an Amyand's hernia with neuroendocrine tumor of the appendix, as in our case, is even more rarely reported.

Renal Squamous Cell Carcinoma Presented With Bone Metastasis and Coexistence With Xanthogranulomatous Pyelonephritis: A Case Report.

Squamous cell carcinoma (SCC) of the kidney is a rare entity. Coexistence of SCC with xanthogranulomatous pyelonephrits is exceedingly rare with only few reports in the literature. We report a case of a 45-year-old male patient with xanthogranulomatous pyelonephritis coexistence with renal SCC in one kidney, which proved radiologically and histopathologically.

Primary follicular lymphoma of the common bile duct mimicking cholangiocarcinoma.

Primary non-Hodgkin's lymphoma of the common bile duct is extremely rare. We present a case with history of inflammatory bowel disease and clinical manifestations of obstructive jaundice. Abdominal magnetic resonance imaging with magnetic resonance cholangiopancreatography (MRCP) was done and demonstrated tight stricture at the middle part of common bile duct, and radiological findings were supportive of extra-hepatic cholangiocarcinoma.
