A high index of suspicion and a rapidly evolving multiple neuraxial involvement led to the diagnosis.

A spectrum of sonographic abnormalities was observed which included echogenic sulci, focal or diffuse increase in parenchymal echoes, ventriculitis, ventriculomegaly with or without aqueductal block, subdural collection, parenchymal infarcts, abscess and subdural empyema. There were two infants with normal sonogram while encephalomalacia was seen in another two patients. An excellent correlation was observed between clinical profile, cerebrospinal fluid biochemistry and sonographic findings.

Age of onset of seizures ranged from day one of birth to day twenty-one. Seizures appeared spontaneously in previously healthy newborns in three cases. All but one survived, and three have near normal development. Isolation of hemorrhage to the periventricular area suggests germinal matrix to be the source of hemorrhage in these cases. These cases also emphasize the need to consider diagnosis of IVH in term-newborns presenting with seizures.

A contrast CT scan of the brain showed a hemorrhagic infarct in the left basal ganglia region with surrounding edema. Echocardiography showed a hydatid cyst in the right atrial chamber extending into the left atrium. A single hepatic hydatid was also seen.

A significant improvement in the osteoarthritis severity index at 2 weeks (p < 0.01) and an improvement in physicians assessment of global arthritic condition at 4 weeks (p < 0.01) was seen with both the treatments. A significant decrease in articular index of joint tenderness (p < 0.05) at 8 weeks and in self assessment of handicap at 4 weeks (p < 0.05), in comparison to baseline, was observed only in patients receiving nimesulide. Rescue therapy was required by a greater percentage of patients being administered piroxicam. Functional capacity improved in 64% of the patients on nimesulide and 74.5% of the patients receiving piroxicam. Adverse effects were observed in 6 patients on nimesulide a...

Although the overall incidence and mortality rate for tuberculosis has decreased over the years, timely and accurate diagnosis of tuberculosis is essential for the health of the patient as well as the public. For the diagnosis of tuberculosis, a high degree of clinical suspicion is required, and this becomes much more important in high-risk populations. Tuberculosis may masquerade as any disease; therefore, tissue and microbiological assessment is sometimes important for establishing the diagnosis. However, in daily practice, the clinician and radiologist should be familiar with the imaging features of pulmonary and extrapulmonary tuberculosis, as well as manifestations of tuberculosis in immunocompromised patients. Imaging provides a very important role in the diagnosis and management of tuberculosis. Although c...

MR imaging provided accurate preoperative information in 91 out of 92 cases (98.9%). Some of the unusual and interesting findings in the series were: presence of intrinsic cord abnormality in 19 out of 21 cases (90.4%) with a normal plain radiograph, 4 cases of diastematomyelia with a dermoid in the dorsal and lumbar region associated with syringohydromyelia, intradural fibrous/glial bands, sgringo-hydromyelia/myelomalacia of the conus with tethered cord syndrome having a normally placed conus, and myelocystocele. It is concluded that MRI is an excellent primary diagnostic tool, together with a plain radiograph, for complete preoperative evaluation of mid-tine spinal anomalies.

The commonest lesion encountered was acoustic neuroma (n=11), followed by neuromas of IX– XI (n=5), meningiomas (n=5), epidermoid (n=3), brainstem tumour with exophytic component (n=9), glomus jugulare tumour (m=3), chordoma with an exophytic component (2) leukaemic infiltrate around nerve (1). T1 as well as T2W1 were obtained in all the patients in spin echo sequences. The study concluded MRI is an modality for the evaluation of suspected CP angle lesion because of no bony artifacts, multiplanar imaging and superior soft tissue contrast resolution.

PML has classically been described in individuals with profound cellular immunosuppression such as patients with AIDS, haematological malignancies, organ transplant recipients or those treated with immunosuppressive or immunomodulatory medications for autoimmune diseases.Methods and case reportsThe authors describe five HIV seronegative
