Jumping the gun : traumatic splenosis mimicking 68-gallium-dotatate avid neuroendocrine tumour

A 54-year-old male presented to the emergency department following a motor vehicle accident. A computed tomography scan incidentally revealed a large lobulated soft tissue density mass in the small bowel mesentery containing central calcification suspicious for a neuroendocrine tumour (NET). The patient's background was significant for a gunshot injury 35 years prior which resulted in an injury to the left hemi-diaphragm as well as a splenectomy. A 68-gallium dotatate positron emission tomography (PET) scan was subsequently undertaken for further evaluation of the potential NET which confirmed a large intensely somatostatin receptor avid mesenteric mass consistent with well-differentiated NET (Figs 1,2).
