MRI brain revealed a questionable tiny pituitary microadenoma
however upon re consultation and discussion amongst the departmental meeting a conclusion was reached that the finding was inconclusive to call it as cushing disease.
was defined as a pituitary tumor of less than 1 cm in diameter and a macroadenoma was defined as a tumor above 1 cm in diameter.
In PDH, which accounts for about 80 percent of dogs, a tiny tumor called a microadenoma
develops in the pituitary gland.
These studies demonstrated that the forced reduction of global DNA methylation levels causes chromosomal instability, promoting the loss of Apc heterozygosity, which leads to increased microadenoma
formation, but also suppresses the transition of early microadenomas
into macroscopic tumors.
Out of these pituitary adenomas 53(84.1%) were macroadenomas and 10(15.9%) were microadenoma
. Post operatively marked improvement in the headache was in all 100% patients and vision improved in 54 (96.4%).
Echocardiograpy, thyroid and scrotal ultrasonography, abdomen CT, hypophysis magnetic resonance imaging (MRI) studies were completed and their results were all normal with the exception of a non-functional pituitary microadenoma
, which was eight mm in diameter.
The first magnetic resonance imaging (MRI) scan showed a right-sided pituitary microadenoma
(b) Steatotic microadenoma
in the mother liver (H&E, x40).
MRI showed a pituitary microadenoma
. In June 2008, she underwent transsphenoidal surgery and the histological examination confirmed a basophil adenoma.

Magnetic resonance imaging showed one patient with microadenoma
and seven with macroadenoma [Table 1].
