Intrasellar arachnoid cysts represent around 1% of all selar lesions. Generally, patients are asymptomatic and when they exhibit visual and/or hormonal disturbances, the indication for surgery is prompted. A 51-year-old woman with a known purely intrasellar cyst diagnosed 23 years prior to presentation, evolved gradual campimetric evaluation. Magnetic resonance imaging showed significant growth...

We report a case of a cerebral aneurysm arising from the bifurcation of the left middle cerebral artery that ruptured into a left middle cranial fossa arachnoid cyst, associated with acute subdural hematoma. We discuss the relationships of aneurysm, arachnoid cyst, and subdural hematoma.

When patients present with spontaneous cerebrospinal fluid (CSF) rhinorrhea the primary diagnostic goal is localizing the site of leakage so that an appropriate approach for surgical repair can be selected. Metrizamide computed tomography (CT) has become the preferred method for investigating CSF rhinorrhea for several reasons [1-4]. CT provides superb bone detail so that fractures or areas of ...

Transpalpebral or trans-eyelid approach is a modified trans-orbital access to lesions of anterior cranial fossa and sellar region. But whether this approach is also suitable for tumors extending laterally to the temporal lobe or middle cranial fossa is not clarified. We would like to share our experiences from the cadaveric anatomy study to clinical operations. We used 5 cadavers to study trans...

Superior semicircular canal (Sup SC) dehiscence syndrome (SSCDS) is a recently recognized syndrome. It consists of a variety of auditory symptoms including autophony, hyperacusis, tinnitus, as well as vestibular symptoms of soundinduced and pressure-induced vertigo. These symptoms arise as a result of the third mobile window effect from a dehiscence of the Sup SC. Since its first description in...

All 377 dry skulls were examined for the occurrence and morphometry of the foramen of Vesalius (FV) both in the middle cranial fossa and at the extracranial view of the skull base. There were 25.9% and 10.9% of FV found at the extracranial view of the skull base and in the middle cranial fossa, respectively. Total patent FV were 16.1% (11.9% unilaterally and 4.2% bilaterally). Most FV were foun...

We present a 43-year-old male patient who developed a giant cholesteatoma with lateral sinus obliteration and involvement of the posterior cranial fossa. The only complaints were left-sided aural discharges and total sensorineural hearing loss. Examination revealed a mass lesion consistent with cholesteatoma within the left middle ear. Computed tomography and magnetic resonance imaging showed a...

BACKGROUND Brain arachnoid cysts are fluid collections of developmental origin. They are commonly detected incidentally in patients imaged for unrelated symptoms. CASE DESCRIPTION A 15-year-old healthy boy with a recent history of head trauma experienced headache that gradually worsened over the course of 10 days. He underwent CT and MRI brain scans which revealed the presence of subdural hae...

Condyle dislocation is defined as displacement of the condyle out of the glenoid fossa while it still remains within the joint capsule [1]. The condyle can be dislocated in many directions, with antero-medial and anterior dislocation being the most common [2-4]. On the contrary, dislocation of an intact condyle into the middle cranial fossa is very rare [24,6]. In general the condyle has a larg...
