Text The patient is a 79 years old male suffering from advanced metastatic prostate cancer. He presented progressively worsening cognitive-motor slowing and was therefore referred to the Emergency
SC
Room of our facility. A plain axial CT scan (A,B) revealed a vast hemispheric subdural fluid collection that seemed to be a subdural hematoma. At closer inspection, and more importantly, in
M AN U
hindsight, it would have been possible to also detect a tenuously iso-hyperdense signal irregularity at the frontal aspect of the fluid collection (*). Because of the poor general medical conditions of the patient and because of the paucity of the neurological impairment, a high-dose corticosteroidbased conservative strategy was implemented. The Total body CT scan for the routine oncological
TE D
follow-up concerning the prostate cancer took place 20 days after the first CT scan at the Emergency Room. (C) A second contrast enhanced axial CT scan showed the presence of two dural metastases, which the initial pathogenesis of the subdural fluid collection can presumably be
EP
ascribed to. The pathogenesis of this condition is generally thought to be linked to: 1. hemorrhagic effusion from the metastatic tissue, 2. dural vessel obstruction by tumor neoplastic invasion,
AC C
3. an angio-desmoplastic reaction of the dural sheets to neoplastic infiltration1.
Keywords: Subdural Metastases, CT, Subdural Hematoma, brain metastases, corticosteroids.
