Malignant neoplasm of brain, unspecified [C71.9], Reason for Study: ^Reason: h/o GBM, intracranial tumor recurrence History: h/o GBM, intracranial tumor recurrence Significant interval increase in size of the left parietal mass with increased extent of surrounding edema [now measures 62.7mm (AP) x 42.4mm (RL) x 61.2mm (CC)].The anterior inferior aspect of the mass shows extension of tumor mass toward left lateral ventricle occipital horn with ependymal enhancement indicating possible ependymal invasion.Previously seen left temporal extra axial mass lesion is not seen on today's scan.There is about 8mm left to right midline shift measured on coronal scan due to mass effect.Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear. Right mastoid air cells show opacification.
1. Significant interval increase of the left parietal mass with extensive surrounding edema and midline shift toward right side.2. Non visualization of the left temporal lobe extra axial mass on today's scan.
