MRI BRAIN Abnormalities in a Case of Spinocerebellar Ataxia (SCA)


Spinocerebellar ataxia (SCA) comprises of a group of neurodegenerative disorders characterized by progressive cerebellar ataxia (either alone or in combination with other neurological system involvement). They are currently classified into various subtypes based on the underlying genetic defect. Currently, there are about 40 subtypes of SCA, referred to as SCA 1, SCA2, ….SCA 40.

Excellent Response to Medical Treatment in a Case of Brain Tuberculoma


Tuberculous infection of the brain is quite common. TB can affect brain and spine in a number of ways- tuberculous meningitis, tuberculoma, brain abscess, Pott’s spine, etc. Brain tuberculoma are commonly seen in India. The patients with tuberculoma of brain present with seizures and focal neurological deficits. Here, I am presenting a 35-year old manContinue reading “Excellent Response to Medical Treatment in a Case of Brain Tuberculoma”

SWI (GRE) Sequences are the BEST to Detect Bleed on MRI Brain


It is extremely vital that we differentiate brain hemorrhage (bleeding) from brain infarcts, when patients present with clinical features of stroke. This is because patients with infarcts are eligible to receive thrombolytic treatment, to lyse the blood clots. On the other hand, thrombolytic treatment is contraindicated in patients with brain hemorrhage (bleed). Drugs used forContinue reading “SWI (GRE) Sequences are the BEST to Detect Bleed on MRI Brain”

Extensive Calcifications on Brain MRI in a case of Hypoparathyroidism


16-year old presented with seizures of five years duration. Seizures were of generalized tonic-clonic type. He was earlier diagnosed to have hypoparathyroidism on the basis of low serum calcium and low PTH levels in blood. MRI brain showed bilateral symmetrical calcifications involving caudate nucleus, globus pallidus, thalamus and dentate nucleus of cerebellum. Calcifications were hyperintenseContinue reading “Extensive Calcifications on Brain MRI in a case of Hypoparathyroidism”

Extensive Calcification in Brain in Fahr’s Disease


36-year old man presented with neuropsychiatric disturbances and developmental delay since childhood. There was no positive family history. Investigations for calcium and phosphorus metabolic disorders were normal. He had no evidence of hypoparathyroidism or pseudohypoparathyroidism. CT brain showed extensive symmetrical calcifications involving bilateral basal ganglia, corona radiata and subcortical regions. A diagnosis of idiopathic nonfamilialContinue reading “Extensive Calcification in Brain in Fahr’s Disease”

MRI Lesions Mimicking Dawson’s Fingers in a Case of Small Vessel ischemia


Dawson’s fingers are periventricular lesions in patients with multiple sclerosis (MS). These are flame-shaped lesions or finger like projections, perpendicular to ventricles and represent perivenular inflammation surrounding medullary veins. Dawson’s fingers are typically seen in patients with multiple sclerosis. However, here, I present a case of small vessel ischemia, whose MRI showed lesions mimicking Dawson’sContinue reading “MRI Lesions Mimicking Dawson’s Fingers in a Case of Small Vessel ischemia”
