"Radiology may no longer be the fairest of all the possible specialty choices for U.S. medical school seniors, according to results of the 2009 National Residency Matching Program. Still, it remains within the top 10 most popular medical specialties.Radiology was the fifth most popular specialty back in 2007 among U.S. senior med students who participated in the NRMP program. By 2009, the specialty had fallen three positions. "

Neuroradiology case approach-Haemangioblastoma

Young male with headache
Differentials include

Vein of galen aneurysm-

  • normally presents early
  • straight sinus will be full and dilated
  • multiple flow voids with thrombosis likely
  • Sup sag sinus will also be full
  • DW could show penumbra of restriction
Pilocytic astrocytoma----------possible
  • unusual location
  • Flow voids unusual as it is low grade tumour
  • perilesional oedema possible
  • No restriction on diffusion
  • normally does not enhance
Pineal gland tumour-------possible
  • usually midline
  • heterogenous enhancement
  • goes to flooor of third ventricle
What we suggested is haemangioblastoma
  • unusual location
  • nodule is typical
  • Bleed not present
  • no oedema usually

Acute Cerebillitis-MRI

Acute cerebellitis is an uncommon clinical entity . It is usually manifested in children. It produces imaging features of cerebllar hemispheric or vermian or both oedema with apparently normal supratentorial compartment. Obstructive hydrocephalus due to aqueductal nannrowing due to oedema is possible The usual agents are viral and amongst them herpes as well as epstein barr virus predominate. In our country it should not be mistaken for Tuberculosis as findings could mimic with leptomeningeal and tentorial enhancement. On admnistration of acyclovir pt may deteriorate if steroid is withheld. Post contrast imaging shows intravascular enhancement (i.e. seeing vessels better in the ROI) which is typical for acute stroke and vasculitis. The etiology of the MRI signal changes and enhancement in cerebellitis remains speculative. The cerebellar swelling and parenchymal signal changes most likely reflect encephalitis with edema and inflammation. The hyperintensities on T2-WI involved the cerebellum diffusely and symmetrically, including the vermis and cerebellar hemispheres; the grey matter appeared more abnormal than the white matter.
