The present study describes the presence of os inca, incomplete metopic suture with asymmetrical frontal sinuses and multiple sutural deformities in a skull bone. Os inca has been reported to be associated with other cranial deformities. However, the present study, besides reporting os inca and associated sutural abnormalities, also highlights the presence of an unusual pterion in such cases. T...

When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage pr...

A 53-year-old woman with superficial siderosis underwent spinal MR imaging, which demonstrated a large cervicothoracic epidural fluid collection compatible with a CSF leak. Conventional and dynamic CT myelography failed to localize the dural tear because of rapid equilibration of myelographic contrast between the thecal sac and the extradural collection. The superior temporal resolution of digi...

Dural sinus malformation is an extremely rare congenital cerebrovascular malformation. We report serial antenatal sonographic findings in two patients with dural sinus malformation. Sonography can reveal dural sinus malformation at 24 weeks' gestation. Correct and early diagnosis may help determine the appropriate place, timing, and mode of delivery, which may result in a better therapeutic cou...

The radiographic appearance of the paranasal sinuses is less accurate in infants and children than in adults, as in infants the cavities are smaller and the margins of the healthy sinuses are often indistinct Moreover, the details of the infantile cranial bones themselves are not sharp owing to the lesser contrast in density between relatively thin bones and soft tissues of the infantile skull ...

Background: Cholesterol granuloma (CG) commonly occurs in the petrous apex; their occurrence anterior cranial fossa CGs is rare. Subfrontal approaches are conventional surgical for resection of midline lesions and frontal sinuses. In this article, we describe a successful minimally invasive approach small CG. Methods: We report rare case air sinus CG extending intradurally through foramen caecu...

BACKGROUND The high pressures documented in the intracranial venous sinuses in idiopathic intracranial hypertension (IIH) could be the result of focal stenotic lesions in the lateral sinuses obstructing cranial venous outflow. OBJECTIVE To explore the relation between venous sinus disease and IIH. METHODS 12 patients with refractory IIH had dilatation and stenting of the venous sinuses afte...
