AIMS To describe the pathology of central nervous system (CNS) fungal infections with particular reference to India. METHODS AND RESULTS This was a retrospective study from 1988 to 2004 constituting 130 cases. The diagnosis was based on morphology of biopsy/autopsy material. These included aspergillosis (n=73), zygomycosis (n=40), cryptococcosis (n=2),(More)
Fifty-six patients with cerebral zygomycosis (mucormycosis) were seen during the period 1971-2001 in two tertiary care hospitals located in south India with tropical climate and catering to neurological diseases. Forty-four patients had rhinocerebral and twelve patients had isolated central nervous system (CNS) zygomycosis. Of these, ten were culture proven(More)
Multiple intracranial aneurysms located bilaterally in the anterior circulation are usually clipped sequentially by separate craniotomies or a bilateral craniotomy. However, in selected patients, bilateral aneurysms can be clipped on both sides in a single sitting through a unilateral approach and unilateral craniotomy without causing morbidity. We present(More)
OBJECTIVE To report three patients with isolated Rosai Dorfman disease of the central nervous system. CASE REPORTS We report two patients with dural-based lesions diagnosed imageologically as meningiomas, and one patient with multiple intraparenchymal lesions diagnosed imageologically as lymphoma. Two patients were males and one was female. All were above(More)
BACKGROUND Lymphomatoid granulomatosis [LYG] is an angiocentric, angiodestructive disease at the higher grade end of the spectrum of angiocentric immunoproliferative lesions. It primarily involves the lungs, but it may also involve several extrapulmonary sites including the central nervous system (CNS), skin, and kidneys. CASE DESCRIPTION Clinical(More)
Of the 21 patients with aspergillosis of central nervous system seen during the years 1990-1997, 16 (76%) had aspergillosis of sino-cranial origin. The occupation in patients with sino-cranial aspergillosis was either agricultural or manual work and predisposing risk factors were present in only two (12.5%) patients. Skull-base syndromes were the presenting(More)
AIM To study the pattern of central nervous system aspergillosis in a tropical country. MATERIAL AND METHODS Case records of patients with CNS aspergillosis seen by the authors in a university hospital in south India were reviewed. RESULTS Of the 21 patients seen during the study period, 16 (76%) patients had intracranial invasion by contiguous spread(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)
