BACKGROUND Timely diagnosis of meningeal carcinomatosis is often difficult even with the assistant of magnetic resonance imaging examination, cerebrospinal fluid analysis, or both. To the best of our knowledge, gadobutrol-enhanced MRI has not been reported in the diagnosis of meningeal carcinomatosis. Here we present two cases where meningeal carcinomatosis was identified on gadobutrol-enhanced...

Despite increasing resistance in the pneumococcus over the past 30 years, there are few cases of treatment failure of non-meningeal infections with high-dosage parenteral penicillin G, which still remains highly effective for many pneumococcal diseases. This is reflected by the new 2008 CLSI breakpoints for parenteral penicillin G of susceptible, </=2 microg/ml, intermediate, 4 microg/ml, and r...

The accessory meningeal artery is misnamed in view of the territory the artery supplies. The name implies that the vessel is an important addition to the middle meningeal artery in supplying the meninges. This is incorrect, because no more than approximately 10% of the blood flow of the accessory meningeal artery reaches the intracranial territory; 90% of the blood is carried to the extracrania...

Non-traumatic multiple saccular aneurysms of the middle meningeal artery are extremely rare lesions. In our case the patient was a 51-year-old woman admitted with complaints of progressive headache. Magnetic resonance imaging showed a dilatation of the vein of galen malformation. Cerebral angiography revealed multiple saccular aneurysms of the middle meningeal artery and fistulous type of galen...

We present the CT, MR angiographic, and histologic findings of a rare primary meningeal melanocytoma of the cavernous sinus. The primary differential diagnosis is between a melanin-containing tumor and an extraaxial cavernous angioma. Radiologic imaging cannot distinguish between the less aggressive primary meningeal melanocytoma and the more aggressive meningeal melanoma.
