Abstract:
Primitive leptomeningeal melanoma is a rare and aggressive condition. The authors report on a case of primitive leptomeningeal melanoma imaged with 99mTc-Sestamibi (MIBI). There was an intense accumulation of the radiotracer in the frontal and parietal leptomeningeal regions and even after injections of gadolinium the MRI continued to reveal a cystic image of the brain. In view of the diagnosis, MRI demonstrated only limited usefulness. On the other hand, this case highlights the important role of MIBI for the imaging of malignant tumors.
