Intussusception is defined as telescoping of a segment of the gastrointestinal tract into the distal bowel. Idiopathic intussusception occurs in children mostly, and it is rare in adults. In this study, our purpose is to present a rare case with adult intussusception. A 54-year-old male patient presents to the emergency department with abdominal pain, nausea, and vomiting for last two days. Direct abdominal imaging showed air-fluid levels. Diagnosis of intussusception is confirmed by further imaging. Intussusception diagnoses verified by indicated “target sign” in computerized tomography. Subsequently, the patient underwent surgery. Ileocaecal intussusception was detected, and affected bowel segment was resected. An ileal submucosal mass with 2 cm in size was detected as the cause of intussusception. The mass described as lipoma in the pathological evaluation. Since its high sensitivity and spesificity, computerized tomography is most valuable diagnostic tool in intussusception. Target sign is a common finding in the tomography. Intussusception is rare in adults, however, intussusception must be held in the differential diagnosis in patients with intestinal obstruction.
