Sister Mary Joseph's nodule is referred to as metastasis of visceral malignancy to the umbilicus. Most common primaries are in the gastrointestinal or genital tract, while other locations are rare. We recently encountered a 76-year-old male who was referred to the surgery clinic with an erythematous nodule in the umbilicus measuring 6 cm in diameter with(More)
Central neurocytomas (CN) are uncommon tumors of the central nervous system, most descriptions of which available in the literature are in the form of isolated case reports and small series. Owing to this rare incidence, diagnosis and management of this neoplasm remain controversial. Usually, these tumors affect lateral ventricles of young adults and(More)
Over the last two decades, an increase in the incidence of PCNSL cases has been reported in the West, both among immunosuppressed and immunocompetent patients. The present study was undertaken to assess the trend of incidence of PCNSL cases in India. To the best of our knowledge, only a single such report is available from India. All biopsy proven PCNSL(More)
INTRODUCTION Meningioangiomatosis (MA) is a rare lesion, probably of malformative origin, consisting of meningovascular proliferation and leptomeningeal calcification. Patients with MA usually present with seizures or persistent headaches. Neurofibromatosis may be associated in a variable proportion of patients, while in others it may be sporadic. Surgical(More)
Stroke is a serious neurological disease, and constitutes a major cause of death and disability throughout the world. The pathophysiology of stroke is complex, and involves excitotoxicity mechanisms, inflammatory pathways, oxidative damage, ionic imbalances, apoptosis, angiogenesis and neuroprotection. The ultimate result of ischemic cascade initiated by(More)
INTRODUCTION Embryonal tumours of the central nervous system (CNS) are the commonest malignant paediatric brain tumours. This group includes medulloblastomas, supratentorial primitive neuroectodermal tumours, atypical teratoid/rhabdoid tumours, ependymoblastomas, and medulloepitheliomas. Earlier, all these tumours were grouped under a broad category of(More)
PURPOSE The spinal accessory nerve (SAN) is conventionally transferred to the suprascapular nerve (SSN) through an incision in the supraclavicular region (the anterior approach) to improve shoulder function in brachial plexus injuries. This approach carries a risk of partial denervation of upper trapezius muscle. Here we describe how dorsal nerve transfer(More)
Glioblastoma multiforme (GBM) Patients generally have a dismal prognosis, with median survival of 10-12 months. GBM with long-term survival (LTS) of (3) > or = 5 years is rare, and no definite markers indicating better prognosis have been identified till date. The present study was undertaken to evaluate GBMs with LTS in order to identify additional(More)
BACKGROUND Rasmussen encephalitis (RE) is a chronic epileptic disorder of unknown etiology, and is clinically characterized by progressive neurological deterioration, focal seizures often progressing to intractable epilepsy, cognitive decline and hemispheric atrophy. AIMS We report the spectrum of neuropathological changes seen in RE, and discuss the(More)
Introduction. The ability to reliably differentiate neoplastic from nonneoplastic specimen and ascertain the tumour grade of diffusely infiltrating gliomas (DIGs) is often challenging. Aims and Objective. To evaluate utility of image morphometry in identifying DIG areas and to predict tumour grade. Materials and Methods. Image morphometry was used to(More)
