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”

Use of Susceptibility-Weighted MRI for detecting calcified Neurocysticercosis


Neurocysticercosis (NCC) is the the commonest cause of symptomatic epilepsy in India and many other countries. NCC infection is caused by Taenia solium (tapeworm). Active NCC infection is suggested by presence of scolex, contrast-enhancement, perilesional edema and cystic appearance on brain scan (CT or MRI, however, MRI is preferred). Active infection increases the risk ofContinue reading “Use of Susceptibility-Weighted MRI for detecting calcified Neurocysticercosis”

CALCIFIED ACTIVE NEUROCYSTICERCOSIS


Neurocysticercosis (NCC) is one of the commonest causes of symptomatic epilepsy in India and many other countries. It is caused by Taenia solium (tapeworm infection). On CT scan, signs of active (alive) worm include: 1. Perilesional edema (seen as hypodensity in plain and contrast images, 2. Enhancement of lesion (disc-like or ring like) on contrastContinue reading “CALCIFIED ACTIVE NEUROCYSTICERCOSIS”
