Rupture of a giant jejunal mesenteric cystic lymphangioma misdiagnosed as ovarian torsion: A case report

Abstract

BACKGROUND Cystic lymphangioma is a rare benign tumor that affects the lymphatic system. Mesenteric lymphangiomas in the small bowel are extremely uncommon. CASE SUMMARY We present a 21-year-old female patient who complained of abdominal pain. The diagnosis of ovarian torsion was suspected after abdominopelvic unenhanced computed tomography and ultrasound revealed a large cyst in contact with the bladder, ovary, and uterus. The patient underwent emergency laparotomy performed by gynecologists, but it was discovered that the cystic tumor originated from the jejunum. Gastrointestinal surgeons were then called in to perform a cystectomy. Pathological examination confirmed the diagnosis of cystic lymphangioma of the mesentery. The patient had an uneventful postoperative recovery. CONCLUSION Mesenteric lymphangiomas can cause abdominal pain, and imaging techniques can help determine their characteristics, location, and size. Complete surgical excision and pathological examination are considered the standard treatment and diagnostic method.
