Adult intussusception, though rare, often signals an underlying issue. This case details ileal perineurioma, an unusual tumor causing small-bowel obstruction, emphasizing its diagnosis through histopathology.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Adult intussusception is infrequent and typically necessitates identifying a pathological lead point.
- Ileal perineurioma, a rare benign peripheral nerve sheath tumor, has scarce reports in the gastrointestinal tract.
Purpose of the Study:
- To report a case of adult ileal intussusception caused by a rare perineurioma.
- To highlight the diagnostic challenges and definitive evaluation methods for this condition.
Main Methods:
- A 59-year-old woman presented with symptoms of small-bowel obstruction.
- Diagnosis involved contrast-enhanced computed tomography and subsequent emergency laparotomy with segmental resection.
- Histopathological and immunohistochemical analyses were crucial for definitive diagnosis.
Main Results:
- Computed tomography revealed ileal intussusception and small-bowel obstruction.
- Surgical resection confirmed ileal intussusception.
- Histopathology identified a spindle-cell neoplasm consistent with perineurioma, confirmed by positive epithelial membrane antigen (EMA) and Glucose Transporter-1 (GLUT-1) staining.
- The patient experienced an uneventful postoperative recovery with no recurrence.
Conclusions:
- Ileal perineurioma is a rare but significant differential diagnosis for adult small-bowel intussusception.
- Definitive diagnosis relies on thorough histopathological and immunohistochemical examination.
- Surgical management and follow-up are essential for favorable outcomes.

Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
