Abstract
BackgroundGastric duplication cysts are uncommon congenital anomalies found primarily in children and rarely seen in the adult population. Accurate diagnosis of cysts before resection is difficult even using the most advanced imaging techniques.Case presentationIn this report, we describe a 28-year-old Moroccan patient with a history of autoimmune hemolytic anemia who presented with an asymptomatic abdominal cystic mass detected during abdominal computed tomography performed before splenectomy. Magnetic resonance imaging performed for accurate characterization showed a high-signal-intensity cystic mass on T2-weighted images, located between the patient’s stomach and spleen. The patient underwent a complete cyst resection during exploratory laparotomy. The histological examination showed a cyst lined by three different epithelia with bundles of smooth muscle, which suggested a gastric duplication cyst.ConclusionsWe report a case of gastric cyst duplication in an adult with autoimmune hemolytic anemia, and we discuss this rare association, radiological findings, and the unique histological findings of this case.
Highlights
Gastric duplication cysts are uncommon congenital anomalies found primarily in children and rarely seen in the adult population
We report a rare case of a patient with Gastric duplication cyst (GDC) with the aim of shedding more light on this uncommon developmental anomaly and on the fact that it should be considered in the differential diagnosis of abdominal cystic masses in adulthood, the clinical and radiological findings are somewhat nonspecific
After 10 months, there were no signs of local complication, and the patient was successfully weaned from steroids and had complete resolution of hemolytic anemia with negative direct antiglobulin tests
Summary
A gastrointestinal duplication is defined as a spherical cystic structure lined by a mucous membrane with smooth muscle in its wall [1]. Case presentation We present a case of a 28-year-old white man with an 8-month history of clinical symptoms of anemia, such as fatigue and breathlessness, without any abdominal complaint He had autoimmune hemolytic anemia treated by corticosteroids for more than 6 months but with a relapse of disease after steroid remission. Magnetic resonance imaging performed for more characterization showed a cystic mass between the stomach and spleen with a high signal intensity on T2-weighted fat-saturated magnetic resonance images (Fig. 1) and peripheral enhancement after gadolinium injection (Fig. 2). At this stage, the differential diagnoses included hydatid cyst, mesenteric cyst, and pancreatic pseudocyst. After 10 months, there were no signs of local complication, and the patient was successfully weaned from steroids and had complete resolution of hemolytic anemia with negative direct antiglobulin tests
