To evaluate the technical success and immediate complication rates of temporary internal jugular vein (IJV) haemodialysis catheter placement in normal and high-risk patients. ⋯ Ultrasound-guided placement of internal jugular vein catheters is very safe with very high success rate and few complications. It can safely be performed in high-risk patients, like patients with disorders of haemostasis and patients with previous multiple catheter insertion in the same vein.

In patients with macroadenoma, posterior pituitary high signal (PPHS) on T1-weighted magnetic resonance (MR) imaging is sometimes observed in an ectopic location. The present study compared incidences of ectopic PPHS before and after macroadenoma surgery using MR imaging, including dynamic MR imaging to ascertain whether this ectopic change is irreversible. ⋯ Greater volume of adenoma is associated with a higher incidence of ectopic PPHS, and the ectopic change is irreversible.
