1/4. Traumatic prepontine tension pneumocephalus--case report.OBJECTIVE: A case of prepontine tension pneumocephalus after temporal bone fracture is presented. CASE REPORT: An 8-year-old girl suffered a head injury due to a fall off her bicycle. She lost her consciousness, and when she was admitted to the local hospital the Glasgow coma Score (GCS) was 8/15 (eye opening: 2; verbal answer: 2; motor response: 4) and there was bleeding from the right ear. The patient's condition deteriorated rapidly and she needed intubation and ventilation. CT of the brain revealed large amount of air in the prepontine region, displacing the brainstem posteriorly. Patient was kept ventilated, meanwhile cerebrospinal fluid (CSF), as otorrhea appeared on the right side. CT was repeated 36 hours later, showing significantly less air in the prepontine area. The patient was weaned off the respirator, extubated and the level of consciousness improved. Later the patient developed meningitis, which was treated by systemic antibiotics with lumbar CSF drainage applied for five days. A high resolution CT scan of the petrous bone revealed a fracture crossing the middle part of the pyramid. Patient showed a full recovery except a right-sided mixed hearing loss. CONCLUSION: Rapid neurological deterioration following head injury can be a consequence of tension pneumocephalus. Prepontine pneumocephalus can be caused by minor fracture of petrous bone. High resolution CT is necessary to visualize minor fracture of the petrous bone. Conservative treatment may be satisfactory to treat tension hydrocephalus.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
2/4. CT findings of head and neck anomalies in lacrimo-auriculo-dento-digital (LADD) syndrome.We present computed tomography (CT) findings of a boy with lacrimo-auriculo-dento-digital (LADD) syndrome. Bilateral lacrimal glands were not detected and CT imaging of this abnormality in LADD syndrome has not been reported before. Despite suggestions from previous reports of multiple temporal bone abnormalities resulting in hearing losses in these patients, only minor temporal bone abnormalities were seen in our deaf-mute patient. Dysplasia of salivary glands was noted. CT findings of head and neck abnormalities in LADD syndrome are discussed.- - - - - - - - - - ranking = 0.5keywords = bone (Clic here for more details about this article) |
3/4. Primary tuberculous petrositis.Tuberculous osteomyelitis of the temporal bone is a rare and dangerous entity that should be included in the differential diagnosis of infectious processes of the base of the skull. We present the case of an 11-year-old child who presented with diplopia, ear discharge and hearing loss. The radiological and histopathological findings revealed tuberculous otitis with osteomyelitis and an abscess in the petrous apex. The child responded to anti-tuberculous chemotherapy. The diagnosis and management of tuberculous osteomyelitis are discussed and a brief review of the literature is presented.- - - - - - - - - - ranking = 0.25keywords = bone (Clic here for more details about this article) |
4/4. Vertically oriented internal auditory canal in an 8-year-old with hearing loss.To report a unique orientation of the internal auditory canal and possible association with congenital hearing loss. Retrospective chart review of an 8-year-old Hispanic male with a mixed hearing loss. Uniquely abnormal orientation of the internal auditory canal in a patient with apparently normal cochleovestibular structures and a mixed hearing loss. A vertically oriented IAC is a rarely described anatomical anomaly of the temporal bone that may have associations with congenital hearing loss.- - - - - - - - - - ranking = 0.25keywords = bone (Clic here for more details about this article) |
