primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

OBJECTIVE The aim of this study was to analyze the type and frequency of cranial computed tomography and magnetic resonance imaging anomalies in patients with idiopathic growth hormone deficiency, and also to investigate the possible relationship between neuroradiological images and the presence of isolated growth hormone or multiple pituitary hormone deficiency. METHODS Magnetic resonance an...

Oesophageal haemangiomas are rare, benign, vascular tumours that have characteristic features on computed tomography and magnetic resonance imaging. This enables radiologists to suggest the correct diagnosis without the need for invasive biopsy. Diagnostic characteristics include phleboliths seen on computed tomography, and intense homogeneous enhancement of the lesion on magnetic resonance ima...

The year of 2012 has seen many significant publications in cardiac imaging, particularly in the modalities of cardiovascular magnetic resonance and cardiac computed tomography. This article will review in brief some of the most important studies with a particular emphasis on the new evidence base for perfusion imaging both by cardiovascular magnetic resonance and computed tomography.

Introduction: According to the literature, optical coherence tomography (OCT) can be used measure radiation absorbed dose. This study was carried out to design a computed tomography system for the calculation of absorbed dose and optimization of dose delivery in radiotherapy using gel dosimeters. Material and Methods: An advanced charge-coupled device based OCT system was developed in laborator...

the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...

Introduction: Orbital metastasis of prostate cancer (PC) is very rare and even more unique in castration-resistant PC (CRPC). In this scenario, choline positron emission tomography/computed tomography (choline PET/CT) is the gold-standard restaging method of choice available in our setting, and new anti-androgens treatments show improvement in overall survival. Case presentation: We report the...

lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. the affected nerve becomes thicker, and it simulates a mass lesion. lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. magnetic resonance imaging (mri) is the key to diagnosis, and it is usually pathognomoni...
