Spontaneous splenic rupture as a primary manifestation of angiosarcoma: a case report

Abstract

Angiosarcoma, a rare endothelial cell tumor, accounts for < 2% of all sarcomas, typically affecting elderly patients. We present the case of a 62-year-old male with a history of hypertension and ischemic heart disease, who initially presented with severe lower back pain. Subsequent imaging revealed a ruptured splenic lesion and multiple liver lesions, leading to a diagnosis of stage 4 angiosarcoma. Post-splenectomy, the patient exhibited pathological vertebral fractures and elevated liver function tests, consistent with metastatic disease. Despite aggressive surgical intervention and supportive care, the patient's condition remained critical. The treatment plan included palliative chemotherapy, spine radiotherapy, and ongoing pain management, with close monitoring of disease progression and response to therapy. This case describes the diagnostic challenges and poor prognosis associated with metastatic angiosarcoma.
