BACKGROUND Cranio-spinal axis teratomas are rare. This subset is interesting because symptoms can be varied, depending on the location. Histopathology is diagnostic; most of the lesions are benign. Rarely, malignancy develops in any of the somatic components. AIMS To study the demographic, clinico-morphological and follow-up data of central nervous system(More)
CONTEXT Extragastrointestinal stromal tumors arising in the pancreas are extremely rare. To date, only eight cases have been reported in the literature. CASE REPORT A 42-year-old female patient presented with gradually increasing abdominal pain of 6-month duration. Computerized tomography scan of the abdomen demonstrated a solid cystic mass in the body(More)
OBJECTIVE To assess outcome of epilepsy surgery in children with medically refractory partial epilepsy evaluated with non-invasive protocol and to determine the predictors of outcome. PATIENTS AND METHODS Retrospective analysis of presurgical, surgical, and postsurgical data was performed in 87 children who had at least 1 year post surgery follow-up.(More)
Glioblastomas (GBMs) are the most common and lethal primary tumors of the central nervous system with high level of recurrence despite aggressive therapy. Tumor-associated proteins/peptides may appear in the plasma of these patients as a result of disruption of the blood-brain barrier in them, raising the scope for development of plasma-based tests for(More)
CONTEXT With the continuing rise in the number of immunocompromised patients, the incidence of invasive mycoses has increased. Various studies have reported the trends of fungal infections in autopsies. Because of limitations in antemortem clinical diagnosis owing to lack of sensitive diagnostic tools, information regarding frequency and pathogenesis of(More)
Aspergillus is a common saprophytic fungus that causes invasive or non-invasive disease in humans. It commonly colonizes pre-existing lung cavities. It has been earlier reported to coexist in previously operated or ruptured hydatid cysts. However there have been only few case reports of its occurrence in previously unoperated cysts in immunocompetent hosts.(More)
PURPOSE To investigate the clinical and mitochondrial DNA (mtDNA) haplogroup background of Indian Leber hereditary optic neuropathy (LHON) patients carrying the m.14484T>C mutation. METHODS Detailed clinical investigation and complete mtDNA sequencing analysis was carried out for eight Indian LHON families with the m.14484T>C mutation. Haplogroup was(More)
Astroblastoma is a rare tumor belonging to the family of primary glial neoplasms. They are classified as neuroepithelial tumors; however, the World Health Organization grading is still not established. We report the case of a 4-year-old child who presented with an intra-axial space occupying lesion which turned out to be an astroblastoma. A complete(More)
BACKGROUND Mycetoma is a chronic suppurative and/or granulomatous inflammatory lesion of skin, subcutaneous tissue, fascia, and tendons caused by the traumatic inoculation of either fungal (eumycotic) or bacterial (actinomycotic) organisms present in the soil. The disease is characterized by triad of tumefaction, discharging sinuses, and grains. MATERIAL(More)
Hemangiopericytomas (HPC) of the central nervous system (CNS) are uncommon dural-based tumors that mimic meningiomas clinically and radiologically. Because there are few reports about these tumors from India, we aimed to study the clinico-pathological and immunohistochemical features of CNS HPC. During 2000 to 2008 all 23 patients diagnosed with HPC of CNS(More)
