BACKGROUND AND PURPOSE The sphenoid sinus is rarely implicated as a site of spontaneous CSF fistula. We undertook this study to evaluate the potential etiopathogenesis of spontaneous CSF fistula involving the sphenoid sinus and to review the imaging findings. METHODS We retrospectively reviewed the imaging findings of 145 cases of CSF fistula from our… (More)
PURPOSE We undertook this study to determine the accuracy of MR cisternography and plain high-resolution CT as a noninvasive alternative to CT cisternography in the diagnosis of CSF fistula in patients with clinically suspected CSF rhinorrhea. METHODS Forty-five consecutive patients with clinically suspected CSF rhinorrhea were examined prospectively for… (More)
Gamma knife was installed at the PD Hinduja National Hospital and Medical Research Centre, Mumbai, India, in January 1997. In the first year of gamma-knife radiosurgery to January 1998, we treated 110 patients, of whom six had medically refractory trigeminal neuralgia. Seven treatments were administered to this group of six patients (one had bilateral… (More)
PURPOSE To correlate imaging abnormalities, clinical features, and postmortem findings in patients with proved cerebral malaria. MATERIALS AND METHODS Twenty-one patients aged 17-50 years with cerebral malaria consented to undergo transverse nonenhanced (10-mm sections) and contrast material-enhanced (8-mm sections in posterior fossa and 10-mm sections in… (More)
A rare complication of transbronchoscopic lung biopsy, namely a cerebral air embolism, is presented. The course of events following the embolic episode in the form of a fall in blood pressure, bradycardia and convulsions is documented, as is the presence of an air emboli on the CT scan of the brain with subsequent resorption of the emboli on the follow-up… (More)
Opportunistic infections are common in patients with AIDS. There is an increasing incidence of tuberculosis, especially extrapulmonary tuberculosis. Splenic abscesses is one such, though rare, extrapulmonary manifestation. We report such a case discuss the diagnosis and treatment in these cases.
We describe three patients with bilateral cerebrospinal fluid (CSF) otorhinorrhea with unilateral progressive hearing loss in whom CT showed the defect to be located in the lamina cribrosa of the internal auditory canal. CT cisternography showed the CSF fistula in two of the three patients who had Mondini malformation, whereas the CSF fistula was obvious on… (More)
A 14-year-old boy presented with a large symptomatic transudative pleural effusion 4 months after spinal surgery for kyphoscoliosis. Computed tomography myelography confirmed a subarachnoid-pleural fistula (SPF) with a pseudo-meningocele communicating with the left pleural space. A review of the literature indicates this to be a rare finding. The… (More)
Hyperimmunoglobulinaemia E (hyper-IgE) syndrome (Job's syndrome) is a rare disease that presents with recurrent cutaneous and sinopulmonary infections, and which begins in infancy and is associated with extreme hyper-IgE. The pulmonary imaging features typically consist of recurrent alveolar lung infections, pneumatocoeles and, occasionally, pneumothorax.… (More)
Computed tomography (CT) is the imaging modality of choice for the demonstration of intercostal lung herniation. The use of forced expiration and Valsalva's manouevre during CT scanning has been recommended in selected cases. We report a case of intercostal lung herniation, demonstrated only on coughing on spiral CT.
