PurposeGliomas constitute the most frequent primary brain tumors. Glioblastoma, the most common and malignant glioma in adults, has dismal prognosis with any current therapy. On the other hand, low-grade gliomas, the second most common type of gliomas, are potentially curative with appropriate treat

Abstract Cerebral Aneurysms (CAs) are characterized by a pathological wall structure with internal elastic lamina and media disruption which leads to focal weakened pouches of the arterial wall. The prevalence of unruptured CAs is estimated to be 2-5% in the general population. During the past few decades, the pathophysiological mechanisms behind the formation, growth and rupture of CAs have been the focus of numerous research studies. In this review, the inflammatory pathways, genetics and risk...
BACKGROUND: Non-specific cardiac symptoms in female patients with rheumatoid arthritis (RA) could indicate early cardiovascular disease. MATERIALS AND METHODS: Myocardial perfusion imaging (MPI), with 99mTc tetrofosmin stress–rest single photon emission computer tomography (SPECT), in 13 RA female patients with atypical cardiac symptoms, was compared to 44 weight- and age-matched females with similar cardiac complaints (control group). Smoking, hypertension, diabetes mellitus, dyslipidemia, obes...
Radiotherapy may result in long term effects and composition alterations in bones. Bone scintigraphy after radiotherapy may demonstrate decreased skeletal uptake; however, this is a transient effect with bone scan normalized after a few years. We describe a case of a 31-year-old female patient treated for left breast cancer with chemotherapy and radiotherapy, exhibiting reduced and diffuse diphosphonate uptake in the heavily irradiated sections of left ribs, even twelve years post-treatment. Sim...
Glioblastoma (GBM) is the most common primary malignant type of brain neoplasm in adults and carries a dismal prognosis. The current standard of care for GBM is surgical excision followed by radiation therapy (RT) with concurrent and adjuvant temozolomide-based chemotherapy (TMZ) by six additional cycles. In addition, antiangiogenic therapy with an antivascular endothelial growth factor (VEGF) agent has been used for recurrent glioblastoma. Over the last years, new posttreatment entities such as...

Even though different imaging modalities are available in sole or in combination for the optimal detection of bone metastases, whole-body bone scintigraphy (BS) in a single session seems to be advantageous. We present an 80-year-old male with unilateral left hypoglossal nerve palsy (HNP) and no other focal deficits on neurological examination. Initial brain computed tomography (CT) scan revealed no pathological findings, while the subsequent cranial CT and magnetic resonance imaging (MRI) scans ...
