Role of magnetic resonance perfusion studies in moyamoya disease
Moyamoya disease, Japanese for 'puff of smoke', is a rare disease that presents most commonly with recurrent TIAs (transient ischemic attacks) / stroke in childhood. Ischemic symptoms in patients with moyamoya disease are usually due to hemodynamically-mediated perfusion failure. Identification of abnormal tissue perfusion is an important aspect of the evaluation of these patients. We present the radiological features including the Magnetic Resonance (MR) Perfusion findings illustrating the hemodynamic changes of cerebral ischemia in a case of moyamoya disease
Case Report - Neuro-cysticercosis with Japanese encephalitis: Magnetic Resonance imaging with diffusion and spectroscopy
Neuro-cysticercosis (NCC) and Japanese encephalitis (JE) are common in
tropical countries. Two cases of NCC with coexistent JE are presented,
which share same socio-demographic and ecologic factors and have the
same intermediate host (pig). Patients were on treatment for NCC and
presented in comatose state. Sudden clinical deterioration of a patient
with NCC should warrant a search for coexistent JE. We report findings
of magnetic resonance spectroscopy and diffusion-weighted imaging of
the JE
Clival and Paraclival Lesions: A Pictorial Review
The clivus is a midline anatomical structure in the central skull base. It is affected by a wide range of non-neoplastic, benign and malignant pathologies, some of which typically affect the clivus because of its strategic location and embryological origins. Clival lesions may often be asymptomatic with occasional complaints like headache or cranial neuropathy in few. Cross-sectional imaging techniques, namely, computed tomographic scan and magnetic resonance imaging, thus, play a key role in approximating to the final diagnosis and estimating the disease extent. In this article, we highlight the important imaging features of various clival and paraclival pathologies to facilitate effective diagnosis, therapeutic planning, and management
