Neoplasm of unspecified behavior of endocrine glands and other parts of nervous system [D49.7] / Encounter for other preprocedural examination [Z01.818], Reason for Study: ^Reason: Pineal tumor, presurgical MRI STEALTH image guidance for tumor resection. This imaging study was performed under stealth protocol, thus multiple fiducial markers attached on the scalp during the examination.Right occipital craniotomy was seen.Redemonstration of irregular shaped and enhancing pineal tumor which shows evidence of infiltration into bilateral thalami and periaqueductal gray matter, superior colliculi and cranial aspect of tectum unchanged since prior scan.Right frontal approach ventriculostomy tube was inserted and the tip is located at the right lateral ventricle frontal horn, unchanged since prior scan.Unchanged right occipital lobe encephalomalacia since prior scan.The ventricles, sulci and cisterns are unremarkable and stable in size. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Preoperative STEALTH protocol brain MRI imaging with multiple fiducial markers.2. Pineal tumor with local extension into bilateral thalami, periaqueductal gray, cranial aspect of tectum and superior colliculus, unchanged since prior scan.3. Stable ventricle size since prior scan with right frontal approach ventriculostomy catheter.4. Unchanged right occipital craniotomy with right occipital encephalomalacia.
