History (HX):
Epilepsy for 10 years
Male 33 yr
Findings:
Multiple small subependymal nodules lining the lateral wall of the lateral ventricles which show same signal intensity as cortex (GM)Diagnostic (DX):
Nodular subependymal heterotopia
Discussion:
Contrast enhanced MRI is recommended to R/O remote possibility of Tuberous Sclerosis
History (HX):
Palpable mass and pain during a few months
Male 39 yr
Findings:
Large well-marginated solid and cystic mass in lower abdomen and pelvis behind the urinary bladder and above the rectum suggestive of a retropritoneal mass.
The solid components of the mass shows marked enhancement on post-Gd images.
Diagnostic (DX):
Low grade spindle cell sarcoma in favour of schwannoma (proved)
History (HX):
Paresis of both upper limbs and right lower limb
Male 75yr
Findings:
Sagital and axial T2WI show symmetric, longitudinally ariented zones of high signal intensity involving the dorsal columns of the spinal cordDiagnostic (DX):
Subacute combined degeneration of the spinal cord (SDC of the spinal cord)
Discussion:
Intramedullary signal abnormalities can resolve after correction of the vitamin B12 deficiency
History (HX):
History of chicken pox 2 weeks ago presenting with seizure and altered mental status and disorientation (now in ICU) Male 8 yr
Findings:
Brain MRI shows gyral swelling and hyperintensity on FLAIR images in right temporo-occipital lobes and medial left temporal lobe . Diffusion restriction is present at these regions and also in thalami.
Diagnostic (DX):
