Lymphangiome kystique du mésocolon: à propos d’un cas.

Intraperitoneal Cystic Lymphangioma (CL) is a rare benign malformative disease of lymphatic origin, with a wide range of clinical symptoms. Diagnosis is based on imaging tests and confirmed by histology. We here report the case of a 54-year-old woman presenting with chronic abdominal pain, with no effect on general condition. Radiological assessment showed a benign mesenteric cystic formation consistent with a cystic lymphangioma. Complete surgical excision of the cystic mass after puncture-aspiration was performed via midline laparotomy, with an uncomplicated postoperative course. Histological examination of the lumpectomy confirmed the diagnosis of LK of the mesocolon. At 12 months, the patient was asymptomatic and no recurrence was observed.
