Adult intussuception as a cause of abdominal symptoms: a case report and review of literature

Sigmoidorectal intussusception caused by colon carcinoma

Intussusception, the invagination of a bowel segment into an adjacent segment, occurs in 5% of adult patients with an obstruction of the bowel. It is often seen as a result of obstructive defecation syndrome or malignancy. However, a sigmoidal malignancy as lead point is rare. Symptoms in adults are less specific than in children, which makes preoperative diagnosis challenging. An 85-year-old female presented with bright red anal blood loss. A large palpable mass was found during rectal examination. A computed tomography was performed during workup, which showed a 'target-sign' on the location of the lesion. An intussusception of the sigmoid into the rectum was seen over the length of 15 cm. This particular type of intussusception is extremely rare. When a neoplasm is suspected to be the lead point, an oncological resection is recommended. We performed a total mesorectal excision, after which the patient had an uneventful recovery.

Intussusception in adults: what radiologists should know

Adult intussusception (AI) is a rare entity with an organic lesion within the intussusception in 70-90% of the cases. Intussusception is classified according to location, etiology, and to the presence or not of a lead point. We illustrate several causes of AI with a variety of radiological findings on plain film, ultrasonography, computed tomography, magnetic resonance, and endoscopy seen at our institution. Imaging plays a major role in their diagnosis and in determining the appropriate treatment.

Gastrogastric intussusception secondary to a gastric carcinoma: Report of a case

Intussusception is uncommon in the proximal gastrointestinal tract, although a few case reports have been published on gastroduodenal intussusception associated with an anatomical abnormality or intussusceptions at a site of gastrojejunostomy after gastric surgery. We herein present a case of gastrogastric intussusception secondary to a gastric cancer, which presented as vomiting and poor oral intake. A 73-year-old woman was diagnosed with gastric cancer during a cancer screening by esophagogastroduodenoscopy and biopsy. Twenty days later, she presented with acute vomiting, a high fever, an increased heart rate, and severe anemia. Esophagogastroduodenoscopy demonstrated that the mass had been intussuscepted into the gastric lumen and distorted the distal antrum of the stomach. Standard distal subtotal gastrectomy was performed without reduction. Her postoperative course was uneventful.

MDCT diagnosis of ileocolic intussusception secondary to an appendiceal mucocele: value of multiplanar reformation

We describe an extremely rare case of an ileocolic intussusception with an appendiceal mucocele as the lead-point and cause of acute right lower quadrant pain in an adult patient. There are only few reported cases of this entity in the radiologic literature. We describe the multislice (computed tomography) CT features and emphasize the value of multiplanar reformations. We also discuss how specific findings on CT should allow for a correct preoperative diagnosis.
