A Large Recurrent Retroperitoneal Lymphangioma in a Previously Healthy Adolescent Male: A Case Report
Abstract
Lymphangiomas are uncommon benign lymphatic vessel tumors that can affect any area of the body served with the lymphatic system. Intra-abdominal lymphangiomas are considered rare, accounting for less than 5 percent of all lymphangioma cases. In this case report, we present a recurrent large retroperitoneal lymphangioma in a previously healthy 15-year-old boy. The patient presented to the Emergency Department with abdominal pain lasting for one week. The pain, described as diffuse, crampy, and non-radiating, gradually increased with time and was aggravated by movement. A large retroperitoneal fluid collection was found on the Computed Tomography (CT) scan. Subsequently, the patient underwent CT-guided drainage, at which 700ml of bloody fluid was extracted. After three months, the patient was readmitted to the hospital for a similar presentation of abdominal fullness and pain. Complete blood count analysis indicated an unremarkable profile, except for a left shift of 82.2% neutrophils and a white blood cell count of 11,300/mcl. A CT scan of the abdomen reported a large, thin-walled cystic lesion in the right hemi-abdomen with minimal thin internal septations, resulting in moderate right hydronephrosis/hydroureter.
