aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

several lesions (inflammatory, neoplastic and congenital) can involve in the skull base. the role of imaging is to detect the location and extension of lesion, determine mass and mass like lesions, differentiate benign from malignant tumors, detect invasion to adjacent structures and make decision in surgical planning. skull base divides to anterior, middle and posterior cranial fossa and some ...

Reports of intracranial retained foreign bodies are relatively rare in the literature. Such objects can cause numerous complications requiring removal, such as infection, persistent cerebrospinal fluid (CSF) leak, or new-onset seizures. The transnasal endoscopic approach provides an excellent alternative to craniotomy for repairing middle cranial fossa (MCF) defects. We describe a case of a 57-...

Anatomically, modern humans differ from archaic forms in possessing a globular neurocranium and a retracted face and in cognitive functions, many of which are associated with the temporal lobes. The middle cranial fossa (MCF) interacts during growth and development with the temporal lobes, the midface, and the mandible. It has been proposed that evolutionary transformations of the MCF (perhaps ...

BACKGROUND AND PURPOSE The possible relationship of orbit deformities in neurofibromatosis type 1 (NF1) to plexiform neurofibromas (PNFs) have not been fully elucidated. Our purpose was to review orbital changes in patients with craniofacial NF1. METHODS We retrospectively reviewed CT and MR imaging abnormalities of the orbit in 31 patients (18 male, 13 female; mean age, 14 years; age range 1...

Patients who have had middle-ear or mastoid surgery are at an increased risk of developing cerebrospinal fluid (CSF) otorrhoea. The CSF leak is usually from defects in the tegmen or posterior cranial fossa. We present a patient with CSF otorrhoea following a modified radical mastoidectomy seven years ago. There was an unusual communication between the internal auditory meatus (IAM) and the midd...

Trigeminal neurinomas are relatively rare tumors and represent 0.2% of all intracranial tumors. (1–12) Trigeminal neurinomas usually arise from the Schwann cells of the sensory root and can originate in any section of the fifth cranial nerve; correspondingly, a variety of symptoms and signs may develop. Improved surgical outcome and long-term growth control have been uniformly reported after th...
