Pretreatment of choriocarcinoma syndrome: a rare complication of metastatic germ cell tumours.

A 27-year-old man newly diagnosed with metastatic testicular choriocarcinoma developed a large right perinephric haematoma secondary to a metastatic deposit in his right kidney. His presentation was also complicated by bilateral iliac venous thrombosis and pulmonary embolism identified prior to initiation of chemotherapy. He underwent multiple attempts at angioembolisation of the bleeding vessels and ultimately angioembolisation of the main renal artery had to be performed to control the bleeding. Following resolution and commencement of chemotherapy, the patient also developed spontaneous intracranial haemorrhage requiring craniotomy.
