Abstract Cerebral toxoplasmosis remains one of the most common focal brain lesions in patients with acquired immune deficiency syndrome (AIDS). Diagnosis is a challenge because on cranial imaging it closely mimics central nervous system lymphoma, primary and metastatic (CNS) tumors, or other intracranial infections like tuberculoma abscesses. A magnetic resonance (MRI) feature postcontrast T1‐weighted sequences considered pathognomonic “eccentric target sign.” The pathological correlate this...
Purpose: Epilepsy following solitary cerebral cysticercosis (SCC) is possibly caused by perilesional gliosis, best visualized on magnetization transfer imaging (MTI).This study aims to describe development of gliosis around SCC prospective serial MTI and correlate this with long-term seizure outcome. Methods: We randomized 123 patients new-onset seizures treatment albendazole plus antiepileptics (treatment), or only (control), performed magnetic resonance (MRI) scans at 0, 3, 6, 12, 24...
We report a case of cerebral phaeohyphomycosis caused by Scytalidium dimidiatum (synanamorph Nattrassia mangiferae) in young, apparently immunocompetent Indian male. Etiological diagnosis was made recovery the fungus culture and histopathological examination. The infection proved fatal despite aggressive antifungal therapy.
Background : Post-concussion syndrome (PCS) associated with mild traumatic brain injury (MTBI) can cause long-lasting disabilities. Magnetic resonance imaging (MRI) evaluation in these patients may demonstrate structural lesions that correlate functional deficits on neuropsychological testing. However, little is known about the significance of relationship between structureal MRI, and outcome MTBI. Aims: To assess MRI PCS following MTBI, to find correlation findings PCS. Settings Design...
To study intracranial cestodal cysts using in vivo proton magnetic resonance spectroscopy ((1)H MRS) an effort to identify metabolite(s) that may help recognizing the parasitic etiology and, perhaps, viability of such tapeworm cysts. Cestodal infestations human central nervous system (CNS)-cysticercosis and hydatidosis-are not rare. Identification a scolex is considered diagnostic cysticercosis on imaging. In its absence, however, features are non-specific.Three patients with hydatid 13...
Subacute sclerosing panencephalitis (SSPE), a post‐measles progressive neurological disorder is still common in India because of indifferent vaccination compliance. However, the acute fulminant form SSPE extremely rare. An unusual case an 18‐year‐old man from south with ultra‐short course 19 days presenting hemiparesis absence myoclonus and cognitive decline, reported. MRI showed frontal parieto‐occipital demyelination extending to nuclear areas. Antimeasles antibodies were demonstrable CSF...
Staphylococcus aureus is the most common bacterial pathogen implicated in pyomyositis. There are increasing reports of community-acquired methicillin-resistant (CA-MRSA) infections. The present case report brings out diverse clinical manifestations MRSA infection form paraspinal pyomyositis, myelitis, spinal osteomyelitis, and pneumonia. Molecular typing organism confirmed diagnosis. Patient was successfully treated with vancomycin surgical drainage. Consideration possibility...
Agenesis and hypoplasia of the internal carotid artery (ICA) are rare congenital anomalies, occurring in less than 0.01% population. We report a case bilateral ICA patient with post-traumatic subarachnoid hemorrhage. describe embryological development cerebral vasculature present review literature.
Purpose: To determine the utility of 3D steady-state MR cisternography in demonstration and localisation cerebrospinal fluid (CSF) leak patients with clinically suspected CSF rhinorrhoea. Material Methods: Six consecutive rhinorrhoea were examined routine evaluation (MRC). All examinations included fast spin-echo (SE) T1WI axial sagittal planes, SE T2WI coronal planes attenuated inversion recovery (FLAIR) images plane. was done using CISS technique 0.7-mm thickness planes. The site extent...

P2 segment aneurysms are located on the posterior cerebral artery (PCA) between junction of communicating with PCA and quadrigeminal cisternal part PCA. We reviewed our experience endovascular coiling in such aneurysms. Clinical pre-procedural data from four patients, referred for treatment aneurysms, were retrospectively studied factors influencing post-interventional neurological deficits caused by ischemia distal territory. Balloon occlusion was done three patients patient tolerance...
