Ossified skeletal muscle hemangioma: radiologic and pathologic features.

Skeletal muscle hemangiomas are relatively uncommon tumors in children and young adults. Although the operative management of these lesions may be affected by their vascularity, the correct preoperative diagnosis is often not made. Ossification of these lesions is rare. Two patients are described whose skeletal muscle hemangiomas contained abundant osseous tissue. This was radiologically reflected by the 'swiss cheese' appearance of the tumors. Such an appearance in an ossified soft tissue mass may allow the correct preoperative diagnosis of this condition.

Fibrous histiocytoma (fibroxanthoma) of a cervical vertebra. A report with a review of the literature.

A patient with a benign appearing intraosseous fibrous lesion of the cervical vertebra is presented. The lesion had the histologic features of non-ossifying fibroma (metaphyseal fibrous defect). Because of its atypical location and unusual radiologic appearance, the lesion was diagnosed as a fibrous histiocytoma, a tumor whose histology is similar to non-ossifying fibroma. The literature was reviewed for similar cases located outside the metaphysis of the long bones. Support is given for designating such lesions as fibrous histiocytomas rather than non-ossifying fibromas.

Computed tomography in planning percutaneous bone biopsy.

Computed tomography (CT) was performed prior to anticipated percutaneous bone biopsy in 19 patients. The CT results were categorized on the basis of how useful they were in prebiopsy planning. In four cases CT was not useful, in four cases it was confirmatory, and in 11 cases it was definitive. CT influenced the choice of biopsy site, needle type, or position in seven of the 11 cases, and it indicated that no biopsy should be performed in four cases. It is concluded that CT is useful in prebiopsy planning and management.

Wear particles: their value in knee arthrography.

The presence of particles in synovial fluid indicates an intra-articular abnormality and can lend support to a positive arthrographic diagnosis. These particles can be readily identified by gross examination at arthrography.

Venous angiography of subcutaneous hemodialysis fistulas.

Venous angiography was performed on 256 subcutaneous arteriovenous dialysis fistulas. The technique involves temporary arterial inflow occlusion, needle injection of contrast material into the venous segment, and rapid sequence roentgenograms as arterial flow is restored. It requires no fluoroscopy or catheterization, avoids trauma to either the brachial or axillary arteries, and can be performed on an outpatient basis. Indications for fistulography included technical complications during dialysis, high-output cardiac failure, aneurysms, sepsis, and other reasons. Studies demonstrated significant stenosis or occlusion, insignificant stenosis, malpositioned needles, excessive fistula flow, aneurysms, thrombus formation, maturation failure, and other and normal findings. Only one study caused fistula thrombosis. Ninety-one percent of the studies provided information useful in the overall clinical management of the patients.

A cause of painful clicking wrist: a case report.

In a patient with symptomatic unilateral clicking of the wrist, a partial tear of the scapholunate ligament with subsequent scarring of the proximal third of the dorsal portion of the ligament had occurred. At operation the dorsomedial edge of the proximal pole of the scaphoid had snapped over the dorsal edge of the lunate as the palmar-flexed wrist was being returned to a neutral position. Release of the scarred portion of the scapholunate ligament was associated with widening of the scapholunate joint space to normal dimensions and cessation of the clicking phenomenon. Fourteen months after operation there was complete relief of symptoms, a full range of wrist motion and no radiographic evidence of widening of the scapholunate space, ligamentous instability, or rotatory subluxation of the scaphoid.

Computed tomography of long-bone osteosarcoma.

Six cases of osteosarcoma, including medullary, parosteal, periosteal, and intracortical types, were studied by computed tomography (CT). In selected cases, CT provided additional preoperative information as to osseous size and soft-tissue extent. CT helped determine intramedullary involvement and specific sites of cortical destruction and thereby helped to plan the surgical approach to biopsy and the definitive excision.

Computed tomography of the osseous pelvis.

Computed tomography (CT) was used for study of the osseous pelvis in 43 patients with definitive pathological or clinical follow-up. CT accurately characterized and determined extent of bone and soft-tissue involvement; neoplasms and other disease processes, such as sacroiliac joint disease, were well localized. In cases of trauma, CT was able to identify, localize, and characterize fracture fragments and bone or joint displacement. CT was judged "useful" or "definitive" in 80% of all lesions and 96% of neoplasms studied.

Brodie abscess: reappraisal.

Upon review, 25 cases of Brodie abscess demonstrated a radiological spectrum not previously appreciated. One third of the lesions were diaphyseal in location, and 50% had associated cortical thickening, while 40% showed a stimulated periosteal reaction, and 20% contained sequestra. The variable radiological appearance was underscored by the fact that the preoperative diagnosis was other than osteomyelitis in half the cases. A diverse nomenclature has proliferated to describe and catalogue bone abscess formation. Although the radiological spectrum is broad, the unanimity of clinical presentation, pathological findings, and response to surgical excision supports the concept of a single entity with variable expression.

Magnification radiography of the temporomandibular joint: technical considerations.

The design, application, and advantages of a temporomandibular joint (TMJ) positioning unit adapted to the RSI microfocus manigification system are described. The reasons for improved TMJ images with this system are discussed and the rationale for film-screen choice presented. The issue of patient radiation exposure is also considered. This system provided superior TMJ images at acceptable levels of exposure.

Carpal injuries: analytic approach and case exercises.

Radiographic wrist relationships are reviewed emphasizing the posteroanterior view, and analyzing the three normal arcs, principles of parallelism, and overlapping articular surfaces. Use of these concepts, which are not stressed in the literature, enables the radiographic interpreter to easily arrive at a definitive diagnosis and to detect and interpret subtle and complex abnormalities. Case material is included to emphasize major different diagnostic points.

Venous angiography and the surgical management of subcutaneous hemodialysis fistulas.

Venous angiography of subcutaneous arteriovenous (A-V)) hemodialysis fistulas involves venous injection of radiographic contrast material which spreads throughout the venous system and into the arteries via the A-V anastomosis when blood flow to the extremity is temporarily occluded. Direct arterial cannulation is avoided. Subsequent restoration of blood flow with rapid sequential roentgenograms differentiates arteries from veins and identifies direction of fistula blood flow. A 44 month experience with 125 consecutive studies in 82 patients was performed with a 0.8% complication rate. Indications for fistulography included insufficient blood flow during dialysis (67%), cardiac failure (10%), aneurysms (6%), sepsis of undertermined site (6%) and other (77%). Roentgenographic findings identified vascular stenoses or occlusions (45%), malpositioned dialysis needles (11%), aneurysms (9%), unsuitable veins for dialysis (6%), absence of septic origin (5%), abnormal flow rates or patterns (5%), technically unsuitable studies (2%) and normal or baseline studies (17%). Information useful in planning clinical management of the patient was obtained in 88% of studies and fistular operations were performed in 65 patients (52%). Venous fistulography can be an effective and safe method of evaluating and planning correction of A-V dialysis fistula complications.

Post-traumatic ligamentous instabilities of the wrist.

Dorsiflexion, palmar flexion, ulnar translocation, and dorsal carpal subluxation are four, not uncommon, post-traumatic carpal ligamentous instabilities. Palmar carpal subluxation is a theoretical possibility. Dorsiflexion and palmar flexion instabilities are named for the way the distal lunate articular surface dorsally and palmarly, respectively. Ulnar translocation, and dorsal and ventral carpal subluxations are named according to movement of the entire carpus at the radiocarpal joint. Early detection of traumatic carpal instabilities is necessary to encourage optimal treatment of these significant carpal malalignments. These and other patients with disabling wrist problems may be evaluated by a "ligamentous instability series."

Shoulder arthrography as a treatment modality.

Some patients undergoing shoulder arthrography with a stiff and painful joint have a small volume capsule or a frozen shoulder. In certain cases when the rotator cuff is intact, the arthrographic procedure has been therapeutic and joint distention has effected a return to normal function. Four such cases are presented.
