No calcification or ascites were observed.

MRI scans of the brain showing regression of pituitary mass

ROCO_01393

Magnetic resonance imaging (T1-weighted with gadolinium) showing cystic changes (arrow) in the multifidus muscle at 4 weeks after the operation.

ROCO_01402

Magnetic resonance imaging of the sella showed a suspicious 5-mm linear shape delayed enhancing lesion at the midline to the left side of the pituitary gland (arrow).

ROCO_01413

MRI T2-weighted imaging: central low-signal-intensity due to the extinguished cystic membrane and a more hypointensive rim of the cyst due to wall calcification.

ROCO_01422

T2-weighted MRI demonstrates disc protrusion at C3-C4, C4-C5, and C5-C6 and corresponding spinal canal stenosis (preoperative MRI). Arrow shows the lesion at the C4-5 level before the operation.

ROCO_01469

Cranial T2 magnetic resonance image for BZ—this shows an enlarged 4th ventricle with cerebellar vermis hypoplasia and horizontally orientated superior peduncles. There is also a posterior fossa arachnoid cyst.
