Benign metastasizing leiomyomatosis (BML) is a rare cause of pulmonary lesions found in reproductive age women who have undergone a hysterectomy for uterine leiomyoma. Given the relative rarity of the disease, the management of these lesions varies from surgical (oopherectomy) or medical antiestrogen hormonal therapy to clinical observation and survelliance. The disease generally presents asymp...

In 136 normal growing children between the ages of 1 and 18 yr, bone mineral content (BMC) at the level of the lumbar spine (L2-L4) was determined with a commercial dual-photon absorptiometer. BMC was calculated as BML (BMC per unit length) and BMD (BMC per unit surface). The mean lumbar spine BML of the studied children (2.53 +/- 0.86 gHA/cm) was significantly lower than the spinal mineral con...

Although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. We report a case of Hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalize...

Modic et al. in 1988 first described characteristic MRI changes in the vertebral body bone marrow and endplates, adjacent to degenerating intervertebral (iv) discs. Depending on the changes in T1 and T2 MRI signals, three types of lesions were identified: Type I lesions (low T1 and high T2 signal) are thought to be clinically active, due to increased blood flow within the bone. Type II lesions ...

OBJECTIVE To determine the relationship of bone marrow lesions (BMLs) with phenomena such as clinical symptoms, histological subchondral bone damage, and development of osteoarthritis, a reliable and reproducible method to localize and quantify BMLs accurately is indispensable. Therefore, the goal of the current study was to develop and validate a novel semiautomated segmentation method based o...

BACKGROUND To describe the scoring methodology and MRI assessments used to evaluate the cross-sectional features observed in cases and controls, to define change over time for different MRI features, and to report the extent of changes over a 24-month period in the Foundation for National Institutes of Health Osteoarthritis Biomarkers Consortium study nested within the larger Osteoarthritis Ini...
