A 32-year-old immigrant woman presented with abdominal pains, nausea, and vomiting. She had not been able to expel gas or feces for 5 days. She had had constipation since birth and had experienced many episodes similar to the current bout. The patient had been hospitalized during infancy in her country, but the cause for her complaint had not been identified. She regularly took laxatives as required. On examination, her abdomen was bloated and tympanic with diffuse tenderness. The rest of the examination and laboratory tests were normal. An abdominal radiograph ([Fig. 1]) and computed tomography scan ([Fig. 2]) showed a dilated ascending and transverse colon, and oval lesions with a radiopaque peripheral ring in the upper left quadrant. Colonoscopy ([Fig. 3]) revealed stenosis of the splenic flexure, which was covered by normal mucosa. The patient underwent surgical resection. Histological studies revealed a normal colon with a 2-cm concentric stenosis of the wall and hypertrophy of the muscular layer. There were no inflammatory, ischemic, or neoplastic changes, or changes in the nerve plexuses, but calcified fecalomas were seen proximally. At 12 months of follow-up, the patient remains asymptomatic with daily bowel movements that do not require taking laxatives.

Congenital stenosis can affect any section of the colon, although it most often occurs in the ascending and transverse segments. Its clinical manifestations are usually chronic constipation and obstructive episodes [1] [2], and it generally is treated by surgical resection within 24 months of birth [3]. In our case, the onset of the symptoms in the neonatal period, the absence of a clinical or pathoanatomical history of inflammatory or ischemic abdominal processes, and the presence of calcified fecalomas suggested a diagnosis of congenital colonic stenosis that had not been identified during infancy. To our knowledge, it is the first report of congenital stenosis diagnosed in adulthood.
