Isolated splenic lymphangioma in adulthood.

Isolated splenic lymphangiomas are rare benign lesions mostly seen in children are exceptionally rare in adults, often discovered incidentally due to their typically asymptomatic nature. This case report elaborates on the surgical excision of a rare splenic cystic lymphangioma in a 33-year-old woman, underscoring the diagnostic and therapeutic challenges these tumors pose. The patient's symptoms, abdominal pain and a palpable mass led to imaging through ultrasound and CT, which revealed a cystic splenic lesion. Total splenectomy was performed, revealing a large cystic mass, with pathological examination confirming a cystic lymphangioma. This case emphasizes the necessity of considering splenic lymphangiomas in adult patients presenting with splenic lesions. It also highlights the critical role of surgical interventions for definitive diagnosis and to prevent complications such as rupture and hemorrhage, thereby emphasizing on the complexity of managing rare splenic tumors.
