CT myelography is an important imaging modality that combines the advantages of myelography and the high resolution of CT. It provides a detailed delineation of pathologic spine conditions, especially those involving the thecal sac and its contents. However, the role of CT myelography has dramatically and appropriately decreased with the advent of...

Background Ileocolic intussusception is a common cause of intestinal obstruction in young children. Radiographs may be of limited value in the diagnosis of intussusception and are sometimes utilized primarily to exclude pneumoperitoneum before therapeutic enema reduction.Objective The goal of this study was to determine if radiographic findings in...

Graft-versus-host disease (GVHD) is a major complication of bone marrow transplantation. Polymyositis with myonecrosis is a rare manifestation of GVHD. Here, we report the case of a 32-year-old man with acute myeloid leukemia who developed GVHD after transplant. He subsequently developed polymyositis, which was diagnosed on PET/CT and confirmed on...

Purpose To systematically evaluate the sella morphology and pituitary gland height on brain MRI of Chiari II malformation (C2M) patients to understand the observed high incidence of apparent enlargement of the pituitary gland. Methods Brain MRIs of C2M patients at a single tertiary care adult institution were retrospectively reviewed. We also eval...

Emergency radiology is a relatively new subspecialty. It is a blend of organ systems and modalities, with dedication to the immediate evaluation of patients with acute conditions. Emergency radiologists provide time-critical support to trauma surgeons and other acute-care providers, using the full gamut of imaging modalities to provide the best car...

Objective: Subglottic squamous cell carcinoma (SCCa) is a rare malignancy representing <5% of all laryngeal cancers. Patients often present with late-stage disease, and survival outcomes are reportedly worse than those for SCCa in other regions of the larynx. Study design: Analysis of a population-based tumor registry. Setting: Academic medica...

Interrupted aortic arch in adults is rare with a limited number of reported cases. We describe a case of a 53-year-old woman with interrupted aortic arch, bicuspid aortic valve, and post-interruption saccular aneurysm of the aorta. To our knowledge, this is only the second report of an adult patient with all 3 abnormalities. We also review the lite...

For patients with cerebral metastasis that are limited in number, surgical resection followed by whole brain radiation therapy (WBRT) is the standard of care. In addition, for high-grade gliomas, maximal surgical resection followed by local radiotherapy is considered the optimal treatment. Radiation is known to impair wound healing, including that...

Background Mucoepidermoid carcinoma (MEC) is the most common salivary gland (SG) malignancy. Primary sinonasal MEC (SN-MEC) is rare. This study analyzes the demographic, clinicopathologic, and survival characteristics of SN-MEC and establishes comparisons with primary major SG-MEC.Methods The Surveillance, Epidemiology, and End Results (SEER) datab...

Arterio-ureteral fistulae are abnormal connections between an artery and the ureter and carry a high mortality. We present two cases of arterio-ureteral fistulae that presented with life-threatening hematuria. Both patients were treated with endovascular covered stent placement.

Central neurocytomas are rare benign tumors of the central nervous system that are typically located in the lateral ventricles. Since they were first reported in the early 1980s, many advancements have been made in terms of their diagnosis and treatment. Despite the progress made, the origin of these rare tumors and effective newer treatment strate...
