ABSTRACT
Primary cerebellar diffuse large B-cell lymphoma (DLBCL) is a rare entity, which manifests with neurological symptoms. It is aggressive in nature with high rate of recurrence and short survival period. It commonly presents with local invasion and rarely spreads outside the central nervous system. Chemotherapy with radiation is the preferred treatment; however, surgery can be done for solitary lesions. Likewise, adrenal lymphoma as primary site of disease is rare but can present as extra-nodal disease. We present an unusual case of cerebellar DLBCL with bilateral adrenal involvement detected incidentally on 18-Fluorodeoxyglucose positron emission tomography (18F FDG PET-CT) scan.

Tumour thrombus is an uncommon complication with ominous outcomes. F18 FDG PET-CT scan helps in differentiating tumour thrombus from venous thrombus owing to its metabolic uptake similar to the tumour. We discuss an interesting case of gastric malignancy with complete splenic vein tumour thrombosis on initial presentation.

Metastasis to umbilicus is often defined as Sister Mary Joseph's (SMJ) nodule. These nodules may be a manifestation of various underlying malignancies, about 50% arising from abdominopelvic cavity most frequently from the gastrointestinal tract. Pancreatic cancer is the predisposing cause in only about 6% of cases and the most common histopathology is adenocarcinomas. We present the case of a 64-year-old male who was found to have a SMJ nodule on staging F18 FDG PETCT scan.

Primary gastric lymphoma is a rare entity which manifests with vague abdominal symptoms and occasionally presents as complications including perforation and haemorrhage requiring urgent management. Chemotherapy has surpassed surgery with advancing medical era. We hereby present an unusual case of primary gastric lymphoma with splenic involvement complicated by localized perforation.
