CT and MR findings in ruptured dermoid cyst in the right parasellar cistern: report of a case.
A case of ruptured dermoid cyst in the right parasellar cistern imaged by MRI and CT is reported. The disseminated lipid droplets were found scattered throughout the subarachnoid spaces including the prepontine cisterns, in front of the right petrous apex as well as bilaterally in the frontal horns. The density of the lipid droplets was comprised between -80 and -100 HU. The lesions were hyperintense on T1-weighted images and hypointense on T2-weighted images.
