Pituitary stalk abnormal enhancement (differential)

A rare case

of pituicytoma-related hypercortisolism in a patient with Cushing syndrome—case report. MRI T1-weighted coronal view same non-enhancing 0.46 × 0.33 cm pituitary lesion

Isolated

Langerhans cell histiocytosis in the hypothalamic-pituitary region: a case report. a Coronal and b sagittal magnetic resonance imaging (MRI) (T1-weighted with gadolinium enhancement) demonstrating an enlarged pituitary stalk and the neurohypophysis hypersignal deficiency. c Coronal and d sagittal T1WI showing the pituitary stalk is a nodular thickening with both size and shape have been changed after the patient discontinued the treatment for 1 month. e Coronal and f sagittal T1WI showing the nodular-thickening pituitary stalk is continuous enlarging after the patient continued the oral drugs for 2 months

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Lymphocytic hypophysitis in a 16-year-old boy who presented with frequent urination, which started when he was 9. Coronal T1WI (a) shows thickening of the pituitary stalk which has intermdiate signal. Post-contrast axial (b) and sagittal (c) T1WI shows thickening of the pituitary stalk with homogeneous enhancement
