Isolated splenic lymphangioma presenting as a huge mass causing anemia and abdominal distension in an adult patient: a case report

Abstract

Abstract Background Lymphangiomas are uncommon benign lesions of lymphatic vessels very rarely affecting the spleen. Isolated involvement of the spleen in adult patients is rarely reported. Case presentation We report a case of a 40-year-old Arabic woman who presented with a 25-cm abdominal mass, fatigue, and anemia evolving for 6 months. Her physical examination revealed anemic syndrome and an enormous splenomegaly extending beyond the umbilical area. An abdominal computed tomographic scan showed a 25-cm splenic mass with multiple hypodense nodules without enhancement after contrast injection. A surgical total splenectomy was performed. Histopathological analysis led to the diagnosis of cystic splenic lymphangioma. The patient’s postoperative course was uneventful, and she was discharged from the hospital. Conclusions Isolated splenic lymphangioma in adult patients is very rare. The preoperative diagnosis is challenging because imaging techniques are not specific. Pathological analysis of the resected specimen is the only effective way to render the definitive diagnosis. Splenic lymphangiomas have a benign course after complete surgical resection.
