Metastatic choriocarcinoma induced separate simultaneous intracerebral haemorrhages: a very rare occurrence and its novel association with Klinefelter syndrome.

Non-traumatic separate simultaneous intracerebral haemorrhages (SSIHs) are rare. Relevant aetiologies are diverse and their diagnosis challenging. We report a unique case of SSIH in an 18-year-old male with a background of previously undiagnosed testicular choriocarcinoma and Klinefelter syndrome. The patient was admitted to Auckland City Hospital with headaches, drowsiness and vomiting. A CT scan revealed SSIH in a background of tumorous lesions. His β human chorionic gonadotropin titre was elevated at 355 000 IU/L. The SSIH and the associated tumorous lesions were acutely surgically resected and the patient started on bleomycin, etoposide and cisplatin combination chemotherapy with excellent results. In this article, we underline choriocarcinoma as a rare aetiology of SSIH and present an example of the clinical presentation, investigation and management of this very rare pathological entity. 2015 BMJ Publishing Group Ltd.
