Neck infections are fairly common in the emergency setting, affecting a broad spectrum of the patient population. Care should be taken not only to distinguish these conditions from other noninfectious origin such as malignancy but also to guide acute clinical management. A familiarity with neck anatomy, the imaging modalities used for investigation of such(More)
A 65-year-old man newly diagnosed with primary muscular non-Hodgkin's lymphoma underwent staging F-18 Fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT). This demonstrated striking FDG uptake involving multiple skeletal muscles. Although a variety of factors may result in diffuse skeletal muscle FDG uptake, the(More)
Computed tomography (CT)-guided lung biopsy is a common diagnostic procedure that is associated with various complications, including pneumothorax, hemoptysis and parenchymal hemorrhage. Systemic air embolism is a very rare (0.07%) but potentially life-threatening complication. We report a fatal case of air embolism to the cerebral and coronary arteries(More)
BACKGROUND AND PURPOSE Incidentally discovered adrenal masses are commonly seen with high resolution diagnostic imaging performed for indications other than adrenal disease. Although the majority of these masses are benign and non-secretory, their unexpected discovery prompts further biochemical and often repeated imaging evaluations, sufficient to identify(More)
Early diagnosis and management of neck infections and inflammatory processes is a common challenge for emergency and ear, neck and throat physicians, as well as radiologists. Emergency neck infections are diverse in their presentation, ranging from a transient enlargement of a lymph node to a rapidly spreading necrotizing fasciitis. Symptoms and signs, with(More)
Head and neck imaging has benefited from 1.5 T magnetic resonance (MR) imaging, providing faster sequences, better soft tissue evaluation, and 3-axis imaging, with less radiation and iodine-based contrast injection. The US Food and Drug Administration has approved human MR imaging at high-field strength up to 4 T in clinical practice. 3 T MR imaging has(More)
Cavitary otosclerosis is a rare presentation of otosclerosis, especially when it involves the anterior wall of the internal auditory canal. Recognizing the computed tomographic imaging features of this process is crucial since cavitary otosclerosis may be a cause of a "third window phenomenon", resulting in conductive hearing loss and can cause(More)
Cetuximab, a recombinant chimeric monoclonal antibody, has been successfully used in the treatment of the head and neck and colorectal cancers. We present a review of its mechanism of action, indications, side effects and economic issues, accompanied by a clinical example from our institution.
Primary calvarial or intra-osseous meningiomas are uncommon lesions often confused preoperatively with other primary or secondary bone tumors of the skull. We present details of a patient with a primary calvarial meningioma involving the frontal, zygomatic, sphenoid and temporal bones that was radiographically diagnosed as fibrous dysplasia and initially(More)
