 There is a 14 x 14 x 20 mm mass involving the left lateral ventricle including the foramen of Monro with extra ventricular extension to abut the left caudate nucleus. There is mild associated enhancement. There is evidence of prior biopsy of this mass via a left transfrontal approach.Remainder of the brain demonstrates no other intracranial mass. No evidence of infarct or recent hemorrhage. There is a punctate focus of susceptibility effect involving the right cerebellar hemisphere consistent with a chronic microhemorrhage. No extra-axial collections. No hydrocephalus. Major flow-voids are preserved. No abnormal parenchymal or meningeal enhancement is appreciated within the remainder of the brain. Minimal scattered opacification is seen of the paranasal sinuses. Mastoid air cells are clear. Calvarium and extracranial soft tissues are unremarkable.Evaluation of the orbits is slightly motion degraded but demonstrates no abnormal mass or abnormal enhancement. The optic nerves are normal in size and signal intensity, and are symmetric bilaterally. Globes appear unremarkable within the limits of MRI. No retrobulbar mass, chiasmatic mass, or parasellar abnormality is seen. Extraocular muscles are also unremarkable.
1. 14 x 14 x 20 mm mass involving the left lateral ventricle which extends laterally into the basal ganglia is consistent with known tumor. This mass has been previously biopsied. No significant intracranial mass effect associated with this lesion. If prior MRI is available to assess for growth, addendum can be made to this report.2. No orbital mass or findings to suggest inflammatory orbital pseudotumor is appreciated.
