A recent study conducted by Zunyi Medical University in Guizhou, China, has provided new information about gastrointestinal stromal tumors (GISTs). The study focused on a rare case of splenosis, which is the implantation of a segment of the spleen into other anatomical sites. In this case, a 16-year-old female with a history of splenectomy presented with recurrent abdominal pain. Initial imaging examinations suggested a gastrointestinal stromal tumor, but further investigation revealed that the lesion was actually splenosis within the gastric myometrium. The study emphasizes the importance of obtaining a comprehensive medical history and utilizing non-invasive diagnostic modalities to accurately diagnose splenosis and avoid unnecessary surgical interventions.

A recent study from Zunyi Medical University in Guizhou, China, discusses the diagnosis of pancreatic focal nesidioblastosis, a rare cause of hyperinsulinemic hypoglycemia in adults. The study presents the case of a 48-year-old man with recurrent hypoglycemic symptoms who underwent positron emission tomography/computed tomography (PET/CT) imaging using dual nuclear tracers to differentiate between nesidioblastosis and insulinoma. The imaging showed increased uptake of fluorine-18-fluorodeoxyglucose (F-18-FDG) but no uptake of gallium-68-labeled 1,4,7,10-tetraazacyclododecane-1,4,7,10-teraacetic acid-d-Phel-Tyr3-Thr8-OC (Ga-68-DOTATATE) in the pancreatic lesion. The study concludes that dual-nuclide tracer PET/CT imaging should be considered when conventional imaging techniques fail to identify the cause of hypoglycemia. [Extracted from the article]
