History of dizzy spells with vertigo on and off since December 2009.. CT of brain without infusion:No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus is detected.There is a slight prominence of the superior cerebellar cistern with a questionable mass effect on the superior aspect of vermis. Although this may be entirely within normal range however I cannot entirely exclude possibly of a cyst in this location. Images through the rest of posterior fossa are entirely within normal limits.Cortical sulci, ventricular system and all other CSF cisterns remain within normal limits. Considering the extent of patient's symptoms further follow-up with an MRI is recommended in particular to exclude possibly to a cyst in the superior cerebellar cistern.
1.Questionable cyst in the superior cerebellar cistern as detailed.2.Unremarkable CT examination of brain otherwise.3.Considering patient's clinical symptoms follow-up with an MRI is recommended.
