E looks good tome. Im thinking of a male equivalent of sheehan's syndrome. wats the answer anyways?
Dear Fox
For Shehaan syndrome threre are two pre-requisites
- Enlarged pituitary gland due to hyperplasia (which is present in pregnancy in female due to excessive demand of prolactin) that is not present in this case
- Hypotension which leads to coagulative necrosis of pituitary (adenohypophysis)
Since first condition is not fulfilled ,so my mind is not catching this option of Shehaan syndrome.
Anyway ,let us wait for actual answer.
Best of luck

Let me analyse the question
The question gives following options
A. Hydranencephaly
B. Linear parasaggital infarction
C. Lacunar infarcts of basal ganglia
D. Parietal lobe hemorrhagic infarct
E. Anterior pituitary necrosis
A= has nothing to do with rise or fall of BP
C= Are characteristics of Hypetension stroke not of Hypotension
D=Again hemorrhage is not a characterisitic of Hypotension
E:A possible candidate but more frequently occur in the postpartum state when pituitary is enlarged with relative decreased blood supply (because pituitary enlarges without proportionate increase in number of blood vessels)
B: It is the most probable answer.
Reason :
As a general principal Watershed areas areas are very voluneralble during global ischemia.This is watershed area between Anterior cerebral artery and Middle cererbral artery running at one finger breadth from superomedial border of each cerebral hemispheper on the superolateral surface.That is why it is called as "parasaggital " in the stem question.
Best of luck
