Clinical question to be answered:? Tumor. Signs and symptoms: Headaches. Prominence of cerebellar sulci and fourth ventricle is consistent with underlying cerebellar parenchymal volume loss. This finding was noted on prior MRI examination of brain. No hemorrhage is detected. Images two supratentorial space demonstrate normal density and morphology of brain parenchymal. Cortical sulci, ventricular system and all CSF cisterns remain within normal. No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus.Calvarium is intact. Mastoid air cells are well pneumatized and unremarkable. Very limited view of ethmoid and sphenoid sinuses demonstrate no abnormality.
1.No evidence of tumor or acute findings.2.Cerebellar volume loss.
