Middle Cranial Fossa Transtemporal Approach to the Intrapetrous Internal Carotid Artery

Multiple intrapetrous aneurysms of the internal carotid artery.

Aneurysms of the petro us portion of the the internal carotid artery are quite rare, there having been only 20 such examples previously reported [1 -7]. Although some aneurysms have been bilateral, there has been no report of more than one aneurysm ipsilaterally. Historically many of the reported cases were originally diagnosed as glomus jugulare tumors until angiography and / or operation led ...

Calcified Middle Cranial Fossa Mass

A 21-year-old male presented for evaluation of transient loss of consciousness and was found to have a hyperdense mass in the left middle fossa. He underwent craniotomy for tumor resection. Intra- and extradural invasion was noted. Gross total resection was achieved. Pathology demonstrated a densely cellular neoplasm with predominately spindle cell morphology in a collagen-containing stroma, ar...

Internal carotid artery occlusion due to idiopathic cranial pachymeningitis.

A 35-year-old black woman had a 6-month history of headaches and a 1-month history of abducens nerve palsy. MR showed a mass in the sella and cavernous sinuses with encasement of the carotid artery. The mass enhanced intensely and homogeneously with Gd-DTPA. Arteriography revealed complete occlusion of the left internal carotid artery and severe stenosis of the C5 and C6 segments of the right i...

Feasibility Assessment of Optical Coherence Tomography-Guided Laser Labeling in Middle Cranial Fossa Approach

Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory ...
