[Pediatric Multiple Endocrine Neoplasia Type 2B with Pheochromocytoma Diagnosed after Perforation of a Colonic Diverticulum : A Case Report].

A 12-year-old girl was found to have decending colon diverticulum perforation and retroperitoneal abscess on computed tomography (CT) carried out to determine the cause of fever and stomachache. CT-guided drainage tube placement was performed. She was suspected of having MEN2B from her specific facial appearance, Marfan-like body shape and lingual mucosa neuroma.
