Parto Teb Azma

History (HX):
Right hemiparesis, inconsciousness, Ataxia

Female   29 yr

Findings:
A large ICH in left frontal lobe in early subacute phase (low signal on T2WI and high signal on T1WI) with extensive peripheral edema.
Important note a small AVM as seprigenous signal void structures at posterior aspect of ICH

Diagnostic (DX):
Large ICH and SAH at left frontal lobe and a small AVM as the underlying cause

History (HX):
Headache   Female   16 yr

Findings:
Cystic mass in right cerebellar hemisphere high signal  on T2WI and low signal on T1WI with thin peripheral enhancement and mild surrounding edema.
Mass effect upon the brainstem and the 4^th ventricle is noted resulting in obstructing hydrocephalus.

Diagnostic (DX):
Astrocytoma grade 2-3 (proved)

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

History (HX):
Known case of breast cancer

Female   48yr

Findings:
Numerous variable sized enhancing masses in cerebral and cerebellar hemispheres mainly at corticomedullary junction  as well as dural and leptomeningeal enhancement and mild to moderate communicating hydrocephalus

Diagnostic (DX):
Brain metastases and carcinomatose

History (HX):
Left hemiparesis for a few weeks

Male   51yr

Findings:
Large left paraspinal mass with cystic component and intraspinal extension through the neural foramina causing pressure effect upon the thecal sac and spinal cord, as well as similar lobulated masses involving the pleura and chest wall (ribs) posteriorly

History (HX):
High intermittent fever and headache for one weeks seizure last night  Male   22yr

Findings:
Mild to moderate communicating hydrocephalus, increased signal intensity in cortical sulci and sylvian fissure on FLAIR images consistent with a pathologic process in subarachnoid space (such as meningitis) and multiple acute ischemic lesions in basal ganglia and in cerebral hemispheres

Diagnostic (DX):
TB meningitis, vasculitis and acute ischemic lesions particularly in basal ganglia

History (HX):
Chronic seizure  for 17 years  Male   32yr

Findings:
Atrophic changes and increased T2 signal intensity of left hippocampus

Diagnostic (DX):
Hippocampal sclerosis

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):
Herpes zoster encephalitis with multifocal

History (HX):
Dementia and progressive memory loss under treatment

Female   65yr

Findings:
Brain MRI shows diffuse cortical atrophy more prominent   in the temporal lobes with temporal horn dilatation (more than 3 mm in diameter) and dilatation of choroidal-hippocampal fissure complex

Discussion:
AD is the most common dementing disorder. Increases in ventricular size, sulcal size, sylvian fissures size and total CSF volume are noted in patients with DAT compared with age-matched control subjects. Atrophy increases over time. The subiculum of the parahippocampal region appears to be most severely affected in DAT.

History (HX):

Female   61yr

Findings:
MIP images of contrast enhanced MRA of neck demonstrate complete obstruction of the left internal carotid artery just above its origin. Mild stenosis at proximal portion of the right ICA also noted.

Diagnostic (DX):

Thrombotic obstruction of the left ICA
