Diagnosis: Other specified endocrine disorders. Lack of coordinationClinical question: drive fiesta sequences recommendedSigns and Symptoms: ataxia. Extraaxial lesion Rt pinealComments: drive fiesta sequences recommended | The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 16 x 11 mm cystic appearing lesion present in the pineal region. It follows spinal fluid on most pulse sequences on the FLAIR MRI and is slightly hyperintense relative to CSF. It does not demonstrate any diffusion restriction. It displaces the vein of Galen and the right basal vein of Rosenthal.. It mildly impresses upon the posterior aspect of the right tectal plate and thalamus. It does not enhance following gadolinium administration. It appears to have multiple compartments.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate a mucous retention cyst in the right maxillary sinus.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
There is a multiloculated cystic lesion present within the pineal region. It is greater than 1 cm in size and mildly impresses on the right half of the tectal plate and thalamus. Although most of such lesions are generally benign, the possibility that this represents a cystic neoplasm cannot be excluded as a result follow up the exams are suggested.
