On brain perfusion SPECT, a primary brain lesion presents as a localized defect that
corresponds to the mass lesion. 99mTc-HMPAO images generally show a focal defect in the …

DISCUSSION Two separate radionuclide cerebral angiograms showed in creased
radioactivity in the cerebrum with recurrent meningio mas during the arterial phase. When …

Menlngiomas comprise 15% of adult intracranial tumors. They are often found in
middle-aged adults and are more likely to occur in women. They are frequently located in …

N-NH3 and F-18 FDG PET for imaging intracranial meningiomas. 1 The authors studied 11
patients with neuroradiologic diagnosis of meningiomas, 10 of which were histologically …

OBJECTIVES: Although meningiomas usually have a benign clinical course, atypical and
malignant types of this brain tumor are associated with high recurrence rates and poor …

A 72-year-old female with nausea and vomiting had high plasma levels of total and ionized

We read with great interest the article by Ko et al. concerning the clinical course of
meningiomas in relation to their histological grade. The authors studied 49 cases of non …

The aim of this study was to look for regional cerebral blood flow (rCBF) abnormalities in
patients with a recent diagnosis of pseudotumour cerebri (PTC) and to compare 99 Tc m …
