Introduction:
Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a rare benign vascular lesion. Because histopathological confirmation is required for a definitive diagnosis, splenectomy is typically necessary. We report a case of laparoscopic splenectomy (LS) for splenic SANT in a patient with a history of Whipple procedure for pancreatic serous cystadenoma.
Case Presentation:
A woman in her 40s presented with a splenic mass 6 months after undergoing a Whipple procedure for a serous cystadenoma of the pancreatic head. Contrast-enhanced CT (CE-CT) revealed a 10-mm low-density, space-occupying lesion in the spleen. Twelve months after the Whipple procedure, follow-up CE-CT demonstrated interval growth of the lesion to 14 mm. Fluorodeoxyglucose PET (FDG-PET) showed increased FDG uptake within the mass. LS was performed for complete resection and definitive diagnosis. Histopathological examination confirmed SANT. The postoperative course was uneventful, and there was no evidence of recurrence 12 months postoperatively.
Conclusions:
We report a rare case of splenic SANT detected after a Whipple procedure and successfully treated with LS to exclude malignancy. Further studies are warranted to establish reliable noninvasive diagnostic approaches for SANT.
