Cerebral cysts [G93.0], Reason for Study: ^Reason: hx of colloid cyst s/p endoscopic removal. eval for recurrence History: none- surveillance No evidence of acute ischemic or hemorrhagic lesion.Susceptibility lesions along the ventriculostomy track through the right frontal lobe as well as at the level of right foramen of Monro are again seen, unchanged since prior scan.On gadolinium enhanced scan, the right hemispheric dura shows diffuse thin enhancement which corresponds to postoperative status. There is no evidence of abnormal brain parenchymal enhancement.Previously seen craniotomy site soft tissue swelling has been completely resolved.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. Retention cyst is seen on the right maxillary sinus and in mucosal thickening was seen on the right frontal sinus, ethmoid sinus and sphenoid sinus.
1. Postoperative status of colloid cyst, postoperative no unusual finding.2. No evidence of acute ischemic or hemorrhagic lesion.
