There was no evidence of primary craniocerebral injury or skull fracture ( Figure 1A ). The repeat head CT indicated that the midline structure was in the middle ( Figure 1B ). The patient was re-examined immediately with head CT, which showed recurrence of the left subdural haematoma ( Figures 1C ). There was no recurrence of the chronic subdural haematoma in the follow-up ( Figure 1D ).
Pathological findings of the haematoma capsule. HE staining (A, B), ERG immunostaining (C), PSA (+) (D), PAP (+) (E), P504S (+) (F), AR (+) (G).

Haematoxylin and eosin (HE) staining showed a multifocal tumour cell nest on the haematoma envelope, the nuclei were obvious and large and deeply stained, the arrangement was sieve-like or solid, and necrosis was visible in the centre ( Figures 2A, B ). All tumour cells were located in the vascular lumen ( Figure 2C ). Staining for PSA, PAP, P504S, and AR was positive, proving that the tumour cells originated from prostate cancer ( Figures 2D-G ).
