Multifocal Haemangioblastoma: Usefulness of MR Examination with a High Dose of Contrast-Medium and Late Acquisition

Abstract

A rare cerebral tumour is described with a particular enhancement pattern in post-contrast medium administration magnetic resonance images.

The tumour was a supratentorial, multifocal haemangioblastoma, whose solid components did not enhance in pulse sequences acquired after contrast medium administration (double dose), but only in later acquisitions (after about 1 hour).

This particular behaviour suggests using contrast medium at high doses with late acquisitions when a cerebral haemangioblastoma is suspected.
