Left: Preoperative, Right: Gross total tumor removal after endoscopic pituitary resection. Drs. Clark Chen and Bob Carter performed an endoscopic pituitary tumor resection of the lesion using a binostral technique.  Endoscopy allows for large field visualization of the tumor and sellar structures.

Imaging:  Diffuse subarachnoid hemmorrhage and hydrocephalusCerebral angiogram revealing aneurysm of supraclinoid carotid.

Treatment: Right external to internal carotid artery bypass with clip trapping of dissecting internal carotid artery segment.  Graft donor vessel: right radial artery. 

Radial artery to M2 graft.

Brain MRILeft temporal mass post gadolinium T1 sequence   shows a left temporal mass without enhancement.  Preoperative MEG reveals expressive speech area just superior to tumor. 

Procedure: Awake craniotomy with intraoperative speech mapping.

Findings: Intraoperative speech mapping revealed complete speech arrest just outside margin of tumor. 

Pathology: oligoastrocytoma

Outcome: Patient with preserved speech function via awake craniotomy technique.

Imaging:  CT scan (Figure 1).  Cerebral Angiography. (Figure 2. )

Figure 2. Cerebral angiogram

 

Treatment:  Two stages of embolization followed by posterior fossa craniotomy for resection of AVM.

Procedure Performed:  Right frontal awake craniotomy with motor mapping.

Pathology:  DNET tumor - DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR
