PURPOSE To depict the normal anatomy of cranial nerves in detail and define the exact relationships between cranial nerves and adjacent structures with three-dimensional reversed fast imaging with steady-state precession (FISP) (3D-PSIF) with diffusion-weighted MR sequence. MATERIALS AND METHODS 3D-PSIF with diffusion-weighted MR sequence was performed and axial images were obtained in 22 hea...

Background: Mucormycosis is a rare, aggressive, and fatal infection caused by fungi of the Mucorales order Zygomycete fungi. mainly found in patients with chronic conditions, clinical cases are observed only immunocompromised uncontrolled diabetes mellitus. Rhinocerebral type most prevalent mucormycosis which has characteristic method spread. Although involvement cranial nerves not common, it c...

AIM This study was designed to determine the anatomic position of the asterion and the relationship between the asterion and the transverse sigmoid sinus junction (TSSJ) in a Chinese cohort. MATERIAL AND METHODS Venous computed tomography (CT) angiography was performed in 32 patients to simultaneously obtain 3D-CT volume rendering images of the cranial bone and the dural sinus. The relationsh...

Dural sinus thrombosis following a head trauma is a rare condition, described in literature along with the lack of consensus regarding diagnosis and management. We present a case of a fifty-year-old man with a head injury and combined supratentorial-subtentorial epidural hematoma who was treated conservatively through the administration of low molecular weight heparin. The diagnosis and managem...

We report a case of an elderly man who presented with hemiparesis and plain CT scan findings highly suggestive of an extradural hematoma as the underlying cause. This patient was later found to have dural metastases secondary to bronchogenic carcinoma. Dural metastases are rare, usually presenting as dural mass, but may also present as chronic subdural or extradural hematoma on non contrast CT ...

Background The pattern of cranial venous drainage in syndromic craniosynostosis is unpredictable and not adequately understood. Collateral channels substitute for stenotic venous sinuses and pose potential risk for surgical intervention. The purpose of this study was to analyze the patterns of venous drainage in patients with syndromic craniosynostosis and their influence on operative planning ...

The observation of apparent dural sinus opacification in a polycythemic patient with cerebral infarction prompted a review of 300 computed tomographic scans for the significance of dense dural sinuses. Fifteen patients including 11 neonates, were identified; each of them had dense dural sinuses and elevated hematocrit or red blood cell indices or both. With only one exception, computed tomograp...

During regular dissection classes, we came across tripled falx cerebelli in a male cadaver. The main (middle) falx cerebelli was large and was attached to the internal occipital crest. It contained the occipital sinus. There were two smaller folds (right and left), one on either side of the falx cerebelli. There were two aberrant venous sinuses; each one connecting the ipsilateral sigmoid and t...

BACKGROUND Several cadaveric studies demonstrate reliable localization of the transverse sinus and the transverse sigmoid junction (TSJ). These studies use the line drawn from the inion to the posterior root of the zygoma (IZ) and the asterion, respectively. We investigated how the size difference between the right and left transverse sinuses (TS) and sigmoid sinuses (SS) affected the accuracy ...
