We describe the CT findings in four patients and the MR imaging in one patient with juvenile ossifying fibroma. Three lesions involved the maxillary sinus and extended to the surrounding structures; one lesion was confined to the maxillary bone. CT scan revealed well-defined, expansile lesions with variable amount of calcifications. On MRI one lesion had(More)
PURPOSE To evaluate magnetic resonance (MR) findings of surgically proved peroneal tendon tears. MATERIALS AND METHODS MR images, medical records, and surgical findings were retrospectively reviewed in the cases of 12 patients who underwent surgery because of suspected peroneal tendon tear (14 tendons). Sagittal and oblique axial T1-weighted spin-echo and(More)
OBJECTIVE The purpose of this study was to describe the MR findings of posterior tibial tendon dysfunction. MATERIALS AND METHODS MR images and medical records were reviewed for 11 patients with surgically proven posterior tibial tendon abnormalities (i.e., tears or tenosynovitis) and for six patients with clinical evidence of posterior tibial tendon(More)
Three patients with localized hypertrophic neuropathy ( LHN ) had a painless, slowly progressive mononeuropathy over many years, resulting in severe focal neurologic deficit. Grossly, the affected nerves showed a fusiform enlargement. Histologically, there was loss of nerve fibers, disorganization of the fascicular pattern, and proliferation of elongated(More)
 Diabetic muscle infarction (DMI) is a rare complication of diabetes mellitus occurring in patients with poorly controlled insulin-dependent diabetes. In previous reports, the diagnosis of this condition was based on the pathologic studies, although MRI examinations were performed in a few patients as part of the diagnostic work-up. In this report, we(More)
OBJECTIVE The purpose of our study was to evaluate the usefulness of diagnostic joint injections in patients with foot and ankle pain when the radiologist attempts to identify the source of pain. This study also correlated the results of injection with outcome after arthrodesis. MATERIAL AND METHODS We retrospectively reviewed the records of 22 patients(More)
There are eight reported cases in the literature of osteosarcomas secreting β-hCG. Our primary aim was to investigate the rate of β-hCG expression in osteosarcoma and attempt to understand the characteristics of osteosarcomas that secrete β-hCG. We reviewed 37 histopathology slides (14 biopsies and 23 surgical specimens) from 32 patients with osteosarcoma.(More)
Intraabdominal panniculitis is a rare, benign idiopathic disorder of the mesentery. Patients usually present with abdominal pain and a palpable mass. The cross-sectional imaging findings are characteristic and consist of a fibrofatty central mesenteric mass lesion encapsulating the mesenteric vessels with displacement of the bowel loops, that can suggest(More)
The aim of this work was to determine the role of MRI in interpreting abnormal signals within bones and soft tissues adjacent to tumor bulk of osteosarcoma and Ewing’s sarcoma in a pediatric population by correlating MR findings with histopathology. Thirty patients met the inclusion criteria, which included (1) osteosarcoma or Ewing’s sarcoma, (2) MR(More)
