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...

OBJECTIVE The objective of this study was to investigate changes in the posterior cranial fossa in patients with symptomatic Chiari malformation type I (CMI) compared to a control group. METHODS We retrospectively reviewed clinical and radiological data from 12 symptomatic patients with CMI and 24 healthy control subjects. The structures of the brain and skull base were investigated using mag...

Ewing's sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing's sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-...

Structures of arachnoid in posterior cranial fossa have been examined during prenatal period. 100 foetuses were examined within IV up to VII month with CRL from 130 mm to 220 mm. Cuts were performed with especially constructed device what enabled ideal cross-section without disturbing of structures of arachnoid of dura mater. Image acquisition was done with the help of digital camera. The very ...

The Anterior Clinoid Processe (ACP) and Middle Clinoid Process (MCP) are sometimes connected by an osseous bridge formed by ossification of Carotico-clinoid Ligament (CCL), converting the distal end of carotid sulcus into an ostium called the Carotico-clinoid Foramen (CCF). Through the CCF passes one of the segment of Internal Carotid Artery (ICA). The CCF is the result of ossification of eithe...

BACKGROUND Nonconvulsive status epilepticus (SE) is a frequent complication in critically ill patients in the intensive care unit. While seizures have been reported in association with subtentorial posterior fossa lesions, the frequency of occurrence of SE among these patients is not known. OBJECTIVES To examine prevalence, clinical features, potential risk factors, and outcome of SE among pa...

OBJECTIVE Posterior fossa hemorrhages may be underdiagnosed in surviving neonates, with cerebellar hemorrhage discovered in 10% to 25% of autopsy specimens from very low birth weight infants. Posterior fossa lesions have been difficult to visualize by the traditional ultrasonography approach through the anterior fontanelle. Late in 1994, routine posterior fossa imaging through the posterolatera...
