anatomy: middle cranial fossa mainly floored by sphenoidal bone and located post. to innominate bone or lesser wing and ant. to temporal bone. main foramens are located in deep part, bilateral to sellae are orbital fissures, optic canals, foramen rotundom, ovale and spinosum, foramen lacerum also meckle cave or trigeminal impression and carotid canal. this fossa is like a butterfly in shape. le...

We describe a patient who sustained a blowout fracture of the superior orbital roof without an orbital rim fracture. The initial CT study (obtained with 10-mm-thick sections) did not show herniation of the intraorbital fat into the anterior cranial fossa; however, thin (3-mm-thick) direct orbital sections showed a fracture of the midportion of the superomedial orbital roof with displacement of ...

INTRODUCTION Temporal bone encephaloceles and cerebrospinal fluid (CSF) leaks are associated with an increased risk of life-threatening intracranial infection. Defects in the floor of the middle cranial fossa are attributed to prior infection, trauma, iatrogenic injury, and increased intracranial pressure. In the temporal bone, intracranial contents most commonly pass through dehiscences in the...

© 2014 Asian Journal of Neurosurgery | Published by Wolters Kluwer ‐ Medknow small and crowded space and any lesion reducing the volume can elevate the intra-cavitary pressure leading to fourth ventricular compression and hydrocephalus, a mechanism may be responsible for brain stem dysfunction in cases of closed depressed fracture of the posterior fossa. As seen in the present case, early surgi...

Extracerebral cavernous angioma is a rare entity; only 45 cases have been reported [1-32] . Thirty-seven of the angiomas, including the two cases reported here, were found in the parasellar region of the middle cranial fossa [1-26] . Differentiation from parasellar meningioma is known to be difficult, since the CT findings are similar. We report the MR findings in two cases of extracerebral cav...

This study focuses on CT and MR studies of adult patient with giant lesion of the posterior cranial fossa associated with micro- and macroaccumulations with density and signal like "fat" at the level of the cortical and cisternal cerebral spaces. This condition is compatible with previous asymptomatic ruptured dermoid cyst. Histological findings confirm the hypothesis formulated using the imagi...

Routine cranial ultrasonography, using the anterior fontanelle as acoustic window enables visualization of the supratentorial brain structures in neonates and young infants. The mastoid fontanelle enables a better view of the infratentorial structures, especially cerebellar hemorrhage in preterm infants. Reports on the usefulness and reliability of cranial ultrasonography using the mastoid font...

treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...

A rare case of synovial chondromatosis with extension to the middle cranial fossa is reported. Synovial chondromatosis, a benign disorder characterized by multiple cartilaginous, free-floating nodules that originate from the synovial membrane is not exclusive to the temporomandibular joint (TMJ). This condition is commonly seen in the axial skeleton and can involve multiple joints. In this case...

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...
