Lymphangioma of the ileum causing acute abdominal pain in an adult, a very rare finding during surgery; Case report with literature review.

introductionLymphangioma of the gastrointestinal tract is very rare, 75 % of the lesions affect the neck and 20 % affect the axillary region, the rest are seen in the mediastinum, the visceral organs, the retroperitoneum, the mesentery, or in the bones. Lymphangioma of the gastrointestinal tract comprises less than 1 %. The majority of cases are asymptomatic but some cases presented with emergency presentations. CASE PRESENTATION: A 31-year-old male presented to emergency department complaining of central abdominal pain for 2 days, with nausea, dyspnea but no vomiting. The abdominal examination revealed a mildly distended abdomen, with guarding and tenderness mainly in the right lower abdominal quadrant. There were no any palpable masses or organ enlargement. The white blood cells count was elevated (14,000 c/mm). Abdominal ultrasound showed an evidence of 10*7 cm multiloculated thick walled lesion in the right lower abdomen, suggesting the possibility of an appendicular abscess. The patient was admitted for 2 days with little clinical improvement. Therefore, a laparotomy was performed at which there were 2 yellowish cystic lesions 60 cm from the ileocecal valve that were arising from each side of the small bowel and related to its mesentery causing luminal narrowing. Resection was done with end-end anastomosis. The histopathology results revealed a diagnosis of ill lymphangioma of the ileum.

conclusionComplete surgical resection is the main form of therapy whenever possible, sometimes is impossible when there is local invasion. When complete resection is performed long term follow up is not recommended as the recurrence is very rare.
