Leiomyosarcoma typically occurs within the uterus, gastrointestinal tract, and mesentery. Primary skeletal leiomyosarcoma is exceedingly rare. The radiographic appearance is similar to that of other aggressive sarcomas of the bone. Definitive diagnosis is achieved through biopsy or excision and pathologic review.

We present a case of hypersensitivity pneumonitis caused by intranasal abuse of the prescription narcotic hydrocodone. The patient's clinical course was complicated by acute respiratory failure. A chest radiograph showed diffuse bilateral opacities. The patient was treated with noninvasive ventilation, a high dose of intravenous steroids, and bronchodilators, resulting in improvement of symptom...

We describe a case in which 120 ml of contrast media was extravasated into the biceps brachii compartment with a power injector during the course of an attempted CT angiogram. The patient underwent surgical fasciotomy and drainage. The radiographic appearance and clinical implications of this event are discussed.

Gout is the most common form of microcrystalline arthropathy, and does not usually pose a diagnostic challenge when patients have a typical presentation, appropriate biochemical picture and classical radiographic appearance. However, magnetic resonance (MR) imaging is increasingly used as the first-line imaging modality in patients with first presentation of joint pain or mass, and tophaceous g...

Twelve patients (17 feet) with progressive neuromuscular planovalgus foot deformity underwent an extra-articular subtalar arthrodesis with the combined Batchelor-Grice procedure. All patients were ambulant and received conservative treatment with braces and special orthopaedic shoes before the operation. Postoperatively the feet were immobilized in short leg casts for 6 weeks. Evaluation was ba...

In the presence of joint space narrowing, it is important to differentiate inflammatory from degenerative conditions. The presence of osteophytes, bone sclerosis, and subchondral cysts and the absence of inflammatory features such as erosions suggest osteoarthritis. Typical osteoarthritis involves specific joints at a particular patient age. When osteoarthritis involves an atypical joint, occur...

Gout is the most common form of microcrystalline arthropathy which usually does not pose a diagnostic challenge when patients have typical presentation, appropriate biochemical picture and classical radiographic appearance. However, formation of gouty tophi in unusual locations and with atypical presentations may mislead clinicians and radiologists, thereby justifying gout nickname as the "grea...

The MR appearance of the corpus callosum was investigated in 80 normal volunteers. Normal variations in appearance were recorded with regard to age, gender, and handedness. The MR studies of 47 patients with a wide spectrum of callosal disease were also reviewed. Abnormalities included trauma, neoplasia, congenital abnormalities, vascular lesions, and demyelinating and inflammatory conditions. ...

Despite their names, simple bone cysts are no longer categorized as cysts since they lack an epithelial lining. However, their nature remains controversial. The internal structure is totally radiolucent, sometimes showing multilocular appearance, although the lesion does not contain true septa and the ridges of bone is produced by the scalloping effect. We presented two cases of histopathologic...

The rheumatoid pneumoconiosis syndrome was originally described as a characteristic chest radiographic appearance in coal-workers associated with clinical rheumatoid arthritis (Caplan, 1953). This association was later confirmed as real and not fortuitous by Miall, Caplan, Cochrane, Kilpatrick, and Oldham (1953) using an unselected population. The original communication defined the radiographic...
