Benign neoplasm of brain, unspecified [D33.2], Reason for Study: ^Reason: assess choroid plexus papilloma History: choroid plexus papilloma There is no evidence of acute ischemic or hemorrhagic lesion.There is about 19.6 mm x 12.3 mm sized the right lateral ventricle occipital horn. The size, configuration and MR signal characteristics do not show any interval change since prior scan.The ventricles, sulci and cisterns are symmetric and 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.Mucosal thickening of the right maxillary sinus with a small retention cyst in the left maxillary sinus.
1. Right lateral ventricle occipital horn intraventricular mass lesions is again seen. Unchanged in terms of size, configuration and MR signal characteristics since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.
