Objectives: We evaluated results of treatment and follow-up of patients with petrous bone lesions.Patients and Methods: We retrospectively evaluat ed 13 patients 5 females, 8 males; mean age 33.8±17.4 years; range 4.5 to 65 years who were treated and followed-up for petrous bone lesions between 1990 and 2004. The diagnoses were cho- lesterol granuloma

Zonography of the petrous temporal bone
The British Journal of Radiology, 1971Abstract The examination of the petrous temporal bone by zonography is presented. The prerequisite theoretical criteria for successful zonography are restated and applied to the radiological examination of the petrous bone. The technique is advocated as a screening examination for abnormalities of the internal auditory canals; as an important addition ...

Mucocele of the petrous temporal bone
American Journal of Roentgenology, 1979Mucoceles result from the accumulation of secretions in an obstructed sinus. Mucoceles of the frontal and ethmoidal sinuses are not uncommon, but are rarely located in the maxillary or sphenoidal sinuses [1-3]. While sphenoid sinus mucocele eroding the petrous temporal bone has been described [4, 5], mucocele originating within the petrous apex itself ...

Haemangioma of the petrous bone: MRI
Neuroradiology, 1992Gd-DTPA-enhanced MRI provided accurate demonstration of the site and extension of a haemangioma of the petrous bone. Enhanced-MRI could allow early detection and differentiation from the other more common tumours of the geniculate ganglion area, thereby permitting the surgeon to remove the tumour, while preserving the facial nerve.

Current opinion in radiology, 1990
High-resolution computed tomography (HRCT) is central to the radiographic study of the petrous bone. The contrast resolution of HRCT more than compensates for its inferior spatial resolution when compared to pluridirectional tomography and the resulting images are clearer and easier to interpret.

Floating Petrous Bone Fracture
Otolaryngology–Head and Neck Surgery, 1989Floating petrous bone fracture appears to occur when the elastic pediatric skull is subjected to large compressive forces. Unlike a longitudinal fracture, a floating petrous bone fracture does not involve the ear canal and squamous cortex. Rather, the fracture line runs through the middle ear, separating the petrous apex from its lateral and inferior ...

Encephalocoele involving the petrous bone
Neuroradiology, 1990The rare occurrence of an encephalocoele through a defect in the tegmen of the petrous bone is reported. The case illustrates the association of this abnormality with recurrent meningitis and the importance of imaging in defining the nature and site of the lesion prior to surgery.

Osteoid osteoma of the petrous bone
Neuroradiology, 1997We present a case of osteoid osteoma of the petrous bone presenting with progressive sensorineural hearing loss. CT showed a dense homogeneous mass at the promontory surrounded by a thin bony border. On MRI this lesion gave intermediate signal intensity on T1- and T2-weighted spin-echo images and enhanced intensely with gadolinium. Surgical removal and

Otology & Neurotology, 2012
The temporal bone shields sensorineural, nervous, and vascular structures explaining the potential severity and complications of trauma related to road and sport accidents. So far, no clear data are available on the exact mechanisms involved for fracture processes. Modelization of structures helps to answer these concerns. Our objective was to design a

Haemangiosarcoma of the petrous temporal bone
The Journal of Laryngology & Otology, 1980An unusual case of haemangiosarcoma of the right petrous temporal bone in a nine-year-old male is presented. A conservative surgical approach and a radical course of mega-voltage radiotherapy were employed in the management of the case. At the time of writing, there is no evidence of any recurrence of the tumour.
