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...

212 Figure 4b: T1W coronal post-gadolinium image just posterior to Meckel’s cave shows thickened right trigeminal nerve (black arrow) and enhancing extradural mass in middle cranial fossa (white arrow) Figure 4a: Contrast enhanced T1W coronal image shows enhancing intracranial extradural mass (black arrow) in the right middle cranial fossa with widened right foramen ovale (white arrow head) Fig...

A 20-year-old woman suffered gradual progression of right pulsatile exophthalmos and slight headache. Computed tomography (CT) demonstrated outward and downward displacement of the right globe and an arachnoid cyst in the right middle cranial fossa associated with thinned and anterior protrusion of a bony orbit. Microscopic cystocisternotomy was performed and the cerebrospinal fluid (CSF) insid...

Background Intracranial dermoid cysts are rare tumors of congenital origin. We report a case of a large dermoid tumor arising in the infratemporal fossa (ITF) with erosion into the middle cranial fossa. After reviewing the literature, we believe this represents the first reported dermoid tumor of the ITF with extension into the middle cranial fossa. Results A 21-year-old women presented with a ...

INTRODUCTION Temporal bone encephaloceles and cerebrospinal fluid (CSF) leaks are associated with an increased risk of life-threatening intracranial infection. Defects in the floor of the middle cranial fossa are attributed to prior infection, trauma, iatrogenic injury, and increased intracranial pressure. In the temporal bone, intracranial contents most commonly pass through dehiscences in the...

BACKGROUND Bony wall damages in the region of the middle and posterior cranial fossa are usually observed in cases of chronic otitis media. These defects can also be congenital, post-traumatic, iatrogenic or due to tumors. They can potentially lead to the development of intracranial complications. MATERIAL/METHODS We analyzed patients who were diagnosed as having bony wall damage in the regio...

BACKGROUND Endoscopic endonasal techniques have recently become the method of choice in dealing with cerebrospinal fluid leak involving the anterior cranial fossa. However, most surgeons prefer an intracranial approach when leaks involve the middle cranial fossa. This case report illustrates the possibilities of using endoscopic techniques for cerebrospinal fluid leaks involving the middle foss...

Extracerebral cavernous angioma is a rare entity; only 45 cases have been reported [1-32] . Thirty-seven of the angiomas, including the two cases reported here, were found in the parasellar region of the middle cranial fossa [1-26] . Differentiation from parasellar meningioma is known to be difficult, since the CT findings are similar. We report the MR findings in two cases of extracerebral cav...

Intrusion of the head of the condyle into the middle cranial fossa is a rare but highly significant result of trauma to the mandible. Various treatment modalities for this type of injury have been reported in the literature. This case report concerns the intrusion of the left mandibular condyle into the middle cranial fossa in an 11-year-old girl. Five days after the original injury, severe lim...
