granulomatöse Hypophysitis

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. A coronal T1-weighted image (left) revealed a iso/hypo-intense sellar lesion with a su-prasellar extension. A gadolinium enhanced image (right) demonstrated an enhancing lesion with a hypointense center

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. T1-weighted coronal (left) and sagittal (right) MRI with contrast demonstrated an intra-sellar and suprasellar mass lesion and thickening of the pituitary stalk with ring-like enhancement

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. Coronal T1-weighted with contrast MRI showed ‘bright spot’ in tuber cinereum of the hypothalamus

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. T1-weighted coronal (left) and sagittal (right) MRI with contrast demonstrated the sel-lar/suprasellar mass lesion was disappeared 3 months after surgery

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. Sagittal T1-weighted (left) and contrast (right): A tumor-like lesion involving the pitui-tary distinct enhancement up to the suprasellar region. Extension of mass along a thickened pitui-tary stalk into the hypothalamus

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. Coronal T1-weighted (left) and contrast (right): Sellar/suprasellar mass, isointense T1 and hyper/hypo-intense in T2 to white matter, with mass effect on the undersurface of the optic chiasm. Mass demonstrates heterogenous enhancement

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. The image of histologic examination and relative MR (upleft). A: Rathke’s cleft cyst; B: show granulomatous hypophysitis of epitheloid macrophages and multinucleated giant cells. C: Eosinophilic granuloma of the skull. HE stain showing granuloma with epitheloid macrophages and multinucleated giant cells

Granulomatous

hypophysitis: experience with eight surgical cases of a single center. T1-weighted sagittal (left) and with contrast (right) MRI demonstrated the sel-lar/suprasellar mass lesion was disappeared 3 months after surgery
