Abstract
BACKGROUND: Magnetic resonance imaging (MRI)-guided biopsy is an emerging diagnostic technique that holds great promise for otherwise difficult to access neuroanatomy. CASE DESCRIPTION: Here we describe MRI-guided biopsy of a suprasellar lesion located posterior and superior to the pituitary stalk. The approach was implemented successfully in a 38-year-old woman who had developed progressive visual deterioration. CONCLUSION: Intraoperative MRI revealed the need for trajectory adjustment due to an unintended, minor deviation in the burr hole entry point, demonstrating the benefit of an MRI-guided approach. Langerhans cell histiocytosis was diagnosed after biopsy, and the lesion regressed after cladribine treatment. Technical nuances of the case are reviewed in the context of the available literature.
