The diagnostic accuracy of MRI in determining the relations between paraclinoid aneurysms and the cavernous sinus.

Purpose: The location of paraclinoid aneurysms is determinant for evaluation of its intradural compartment and risk of SAH after rupture. Advanced MRI techniques have provided clear visualization of the distal dural ring (DDR) to determine whether an aneurysm is intracavernous, transitional or intradural for decision-making. We analyzed the diagnostic accuracy of MRI in predicting whether a paraclinoid aneurysm is intracavernous, transitional or intradural.

Calvarial ectopic meningothelial meningioma.

Background: Meningiomas are the most common benign neoplasm of the brain whereas ectopic presentation, although reported, is rare. Among these ectopic tumors, there are a group of purely intraosseous meningiomas, which usually are diagnosed differentially from common primary osseous tumor such as fibrous dysplasia and osteoid osteoma.

Case Description: We report a 62-year-old female with a history of headaches and 6 months of progressive right parietal bulging, with no neurological signs.

Audiologic evaluation in patients with acquired hypothyroidism.

Unlabelled: Hearing loss in hypothyroidism has been reported by many authors but its pathophysiology is unclear.

Aims: to study the audiological evaluation of patients with acquired hypothyroidism.

Materials And Methods: two groups were included: a hypothyroidism group (HG, n-30), and a control group (CG, n-30).
