Preoperative depiction of cavernous sinus invasion by pituitary macroadenoma using three-dimensional anisotropy contrast periodically rotated overlapping parallel lines with enhanced reconstruction imaging on a 3-tesla system

Abstract

Preoperative evaluation of pituitary macroadenomas using 3DAC PROPELLER MR imaging on a 3-tesla system is likely to be a powerful noninvasive method of detecting cavernous sinus invasion, which can potentially dominate the therapeutic strategy for these lesions.

Pituitary Adenomas and Invasiveness from Anatomo-Surgical, Radiological, and Histological Perspectives: A Systematic Literature Review

“…Recently, radiomics is playing an increasingly important role: its preoperative prediction of CS invasion based on contrast-enhanced T1 and T2-weighted magnetic resonance (MR) imaging might support clinical decision-making and predict outcomes [127]. Three-dimensional anisotropy contrast (3DAC) MR imaging [128], CE-MRA 3T (contrast-enhanced MR angiography) [129] or CE 3D FIESTA (contrast-enhanced 3D fast-imaging employing steady-state acquisition) [130] might be used to evaluate CS invasion and study the involvement of its cranial nerves.…”

Assessment of Normal Perisellar Anatomy in 1.5 T T2-weighted MRI and Comparison with the Anatomic Criteria defining Cavernous Sinus Invasion of Pituitary Adenomas

“…In all these cases, Nn. III and V1 were encapsulated up to at least 50 % by the tumors (100 % sensitivity and 100 % specifi city [28] ). However, the MW of CS was not detectable with this technique.…”

Insidious Extension of Pituitary Prolactinoma: Two Can't‐Miss Findings Depicted on a 3.0‐T MR System

“…In our cases, however, 3DAC‐MR imaging demonstrated CSI of pituitary adenoma: decreased water‐diffusivity due to tumor invasion into the cavernous sinus (CS). This indicates another clinical application of 3DAC‐MR imaging in contradistinction to our previous report which depicted cranial nerves in the cavernous sinus 7 . Some prolactinomas slip through the examination when using a 1.5‐T MR system, 2 and it is important to remind neurosurgeons of this when treating pituitary adenomas.…”

Their features included no shift of pituitary stalk, indistinct intrasellar mass, intrasellar creeping extension, and the extrasellar main body of adenoma in our series.…”
