What is the differential diagnosis for the hyperdense temporal mass?
Differential diagnosis is broad, but includes: - Hematoma (e.g. from amyloid angiopathy, venous sinus thrombosis, vasculitis) - Tumour, either hemorrhagic or non-hemorrhagic but hypercellular (e.g. glioblastoma, metastases, lymphoma/leukemia) - Vascular malformation (e.g. cavernous or arteriovenous) - Cerebral contusion - Infectious (e.g. tuberculoma)
Small spontaneously hyperdense intra-axial lesion in the left temporal pole with surrounding edema.
