High-resolution CT of temporal bone trauma.
Computed tomographic (CT) findings in 18 patients with temporal bone trauma were reviewed. Eight patients suffered longitudinal fractures of the petrous bone, which were associated with ossicular dislocation in two patients. Transverse fractures were detected in six patients, with a contralateral mastoid fracture in one patient. In four patients, the fractures were restricted to the mastoid reg...
متن کاملDual-time-point FDG-PET/CT Imaging of Temporal Bone Chondroblastoma: A Report of Two Cases
Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...
متن کاملPneumolabyrinth after temporal bone fracture: documentation by high-resolution CT.
The incidence and clinical features of temporal bone fractures have been well documented in the medical literature. Characteristically, longitudinal fractures account for 80% of the total [1, 2] and result from trauma to the parietal and temporal regions of the skull [3]. The fracture line starts at the tympanic annulus and runs parallel to the petrous pyramid, traversing the external auditory ...
متن کاملHigh-resolution CT of the temporal bone in dysplasia of the auricle and external auditory canal.
PURPOSE To determine CT findings in the external, middle, and inner ear of patients with microtia and external auditory canal dysplasia. METHODS We used high-resolution CT, with multiplanar or axial 1-mm continuous sections, coronal or sagittal reformations, or low-dose spiral acquisitions, to examine 184 temporal bones of children with microtia. RESULTS In cases of minor microtia, auditory...
متن کاملDiagnostic value of CT and MRI of Temporal Bone in Cochlear Implantation Candidates
Background Cochlear implantation is an approved treatment which can be used to treat severe to profound hearing loss. Imaging before cochlear implant surgery is very important in decision making and assessing the temporal bone anatomy for surgery. We aimed to assess the diagnostic value of high resolution CT scan (HRCT), and MRI of temporal bone in candidate pati...
