Complete splenic vein tumour thrombus in primary gastric malignancy on F18-fluorodeoxyglucose positron emission tomography-computed tomography.

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.

Targeting the neighbour: Primary gastric lymphoma with concealed splenic perforation.

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.
