Clinical question: Cerebellar lesion. Signs and symptoms: same. Nonenhanced head CT:A high density mass or a hematoma is noted in the right cerebellum measuring 17 x 27 mm in its trans-axial dimensions.There is subtle surrounding vasogenic edema and mass effect on the fourth ventricle. The fourth ventricle however remains widely patent. There is no evidence of crowding at the level of foramina magnum or mass effect at the level of quadrigeminal plate cistern. Recommend follow-up with dedicated pre-and post enhanced MRI to further assess the lesion. This examination is otherwise unremarkable. The cortical sulci, ventricular system, CSF cisterns and gray -- white matter differentiation remains within normal.Calvarium is intact. Positive cells, paranasal sinuses are unremarkable.
