3 T MRI visualising flow voids in pituitary Macroadenoma. Hypophyseal artery(supplying pituitary gland/tumor) and McConnel Capsular artery (Osteo dural artery 1953).
These flow voids size changes with size of tumor until they get compressed by tumor large size of tumor. In smaller size of tumor, traction on these direct branches while
Tumor decompression might lead to tear in ICA. It might bleed immediately or can form pseudo aneurysm.
In this case, we were well aware of these flow voids. Four handed approach, Early identification, bipolar coagulation and sharp dissection without traction helped in achieved safe resection of pituitary adenoma.
Patient had uneventful post operation course.
