A unique case of malignant neoplasm--choriocarcinoma in a 24-year-old man--difficulties in differential diagnostics of intracranial injuries in the aspect of medicolegal opinion

Differential diagnostics of pathologic and traumatic lesions based on image techniques may in some cases cause serious difficulties or even be the cause of a medical error resulting in incorrect medicolegal opinion. The authors present a unique case of primary malignant neoplasm of the testicle (choriocarcinoma) in a 24-year-old man. Several days after the event, he was admitted to Department of Neurology with CT-confirmed traumatic intracerebral hematoma communicating with the ventricular system. Discharged in a good general condition, the patient died several days later. A postmortem examination combined with histopathology demonstrated numerous metastases of the primary carcinoma, which also involved the brain, arousing suspicions of head injury in consequence of a crime.
