Repair of distal biceps tendon ruptures using a suture anchor and an anterior approach.

In a prospective study, eight consecutive patients with nine ruptures of the distal biceps tendon underwent repair through a single incision. All patients were satisfied with their clinical results and had full ranges of elbow and forearm motion. There were no radial nerve injuries and no radio-ulnar synostoses. Isokinetic testing, after correction for dominance, demonstrated a 6% strength deficit, but 7% higher endurance in the repaired extremity for the flexion-concentric test, and no strength deficit and 13% higher endurance for supination. The improved endurance is probably explained by initial reduced effort due to apprehension which minimized subsequent fatigue.

Neurovascular compression by a subpectoral lipoma. A case report of a rare cause of thoracic outlet syndrome.

BACKGROUND: Lipomas are benign soft tissue tumours, progressively expanding in volume. Beside frequent aesthetic consequences, lipomas can also exert pressure on surrounding tissues and structures. MATERIALS AND METHODS: A case of a subpectoral infraclavicular lipoma compressing the axillo-subclavicular neurovascular bundle, produced unilateral brachialgia, thereby simulating a Thoracic Outlet Syndrome. The expansive, but non-infiltrative, nature of the lipoma allowed local excision in the vicinity of the brachial plexus and infraclavicular vascular structures. RESULTS: Surgical removal of the lipoma resulted in complete remission of symptoms in the left arm and hand. CONCLUSIONS: In the presence of unilateral brachialgia, a subpectoral tumour causing a Thoracic Outlet Syndrome should always be excluded in the absence of other relevant pathology.

Hemangiopericytoma of the parotid gland: CT and MR features.

Hemangiopericytomas are uncommon vascular neoplasms with rare occurrence in the head and neck region. They originate from the pericytes, which are small, oval cells encircling capillaries. Hemangiopericytomas traditionally appear in the retroperitoneum and in the capillaries of the extremities. A case of hemangiopericytoma of the parotid gland is presented. The clinical, surgical, histologic, and radiologic features are described and discussed.

Intralobar pulmonary sequestration supplied by the right coronary artery.

Bronchopulmonary sequestrations are malformations that are often congenital; they consist of isolated nonfunctioning lung segments having no communication with functional tracheobronchial elements of the surrounding lung. They are supplied by single or multiple branches from the distal thoracic or proximal abdominal aorta, or from the celiac, splenic, intercostal, subclavian, or pulmonary artery. Due to the absence of ventilation, the lung tissue can become chronically infected. We describe an intralobar pulmonary sequestration with arterial supply from the right coronary artery.

Hypertrophy and pseudohypertrophy of the lower leg following chronic radiculopathy and neuropathy: imaging findings in two patients.

Enlargement of the ipsilateral muscle compartment is an exceptional finding in patients with chronic radiculopathy, peripheral nerve injury, anterior horn cell diseases, or acquired peripheral neuropathy. We report radiographic, ultrasonographic, CT and MRI findings in a patient with chronic S1 radiculopathy and another with chronic neuropathy of the common fibular nerve (L4-S2), both presenting with painless enlargement of the calf muscles.

Non-invasive diagnostic assessment of extensive vertebral artery tortuosity with enlargement of the intervertebral foramen.

Two cases with an incidental finding of a widened intervertebral foramen due to extensive tortuosity of the vertebral artery are presented. Computed tomography angiography and magnetic resonance imaging/magnetic resonance angiography (MRA) both proved to be useful as non-invasive techniques to provide the diagnosis. In-plane saturation is a disadvantage seen with the two-dimensional time-of-flight MRA technique.

Mycotic pseudo-aneurysm of the extracranial carotid artery.

A rare case of mycotic pseudo-aneurysm of the common carotid artery as a complication in an immunosuppressed paediatric patient is presented. Treatment of pseudo-aneurysms of the common carotid artery is generally considered to be an emergency, necessitating quick and accurate diagnosis. In patients with septicemia, angiography has to be avoided. We were able to provide the surgeon with the exact diagnosis and accurate topographical information with helical CT with 3D reformation.

Basilar and distal vertebral artery occlusive disease: correlation of MR imaging and MR angiography.

The purpose of this study is to evaluate the correlation of brain lesions seen on magnetic resonance imaging with vascular occlusive disease of the basilar and distal vertebral arteries as documented on MR angiography. The clinical findings are also correlated with the findings on MR imaging and MR angiography. The clinical records of twenty-one patients with proven occlusive disease of the distal vertebral and/or basilar arteries were retrospectively reviewed. All the patients were imaged utilizing either the Siemens Magnetom 1.5 T SP 4000 and the Siemens 1.0 T Impact systems. Dual MR angiographic techniques were employed including two-dimensional (2D) and three-dimensional time-of-flight. The 2D sequences utilized fast low angle shot gradient echo sequences. The 3D sequences utilized fast image steady-state precession gradient echo sequences. Gadolinium contrast was utilized for increased angiographic detail in one patient. Magnetization transfer contrast was used in three patients. The individual partitions as well as the maximum intensity pixel projection images were evaluated in each case. The most extensive brain lesions were seen in the group of patients with severe basilar and/or combined vertebrobasilar disease. One-half of these patients showed non-specific scattered foci of T2 lengthening similar to the findings found in a group of patients with noncritical stenosis. MR imaging invariably demonstrated more lesions than were clinically suspected. Even though the brain lesions tended to be more extensive in patients with severe vascular disease, the amount of brain tissue damage was not an adequate parameter to document the degree of vascular narrowing. The degree of vascular narrowing was useful in therapy planning. Such data was obtained by the MR angiograms, but not by MR imaging. MR angiography is a useful complementary examination when lesions in the basilar and distal vertebral vascular territories are diagnosed on MR imaging. MR angiography can differentiate critical from noncritical stenosis and can thus play a key role in the therapeutic decision making process.

Case report 813: Hibernoma of the left thigh.

The MRI features of a hibernoma have been described, as no previous report of MRI findings was found in the literature. The hibernoma presents as a well-delineated soft tissue mass with tissue attenuation intermediate between that of skeletal muscle and subcutaneous fat. Marked contrast enhancement is noted.

Occipital condyle fracture must be considered in the pediatric population: case report.

To our knowledge, no case of occipital condyle fracture after minor head trauma in the pediatric population has been published. We report the case of a 12-year-old girl with a Jefferson's fracture detected on x-ray films. Axial high resolution computed tomography and coronal reconstruction images demonstrated the additional occipital condyle fracture.

Aortocaval fistula: CT appearance with pathological correlation.

Atherosclerotic aneurysm of the abdominal aorta is a frequent finding in a general hospital patient population. Most complications such as rupture, thrombosis and superinfection are well known. We report on a patient with aortocaval fistulization. This rare complication was diagnosed on contrast enhanced computed tomography. Pathological correlation was obtained as attempted surgery was unsuccessful.

Small bowel metastases from malignant melanoma.

Metastases of malignant melanoma to the small bowel are only rarely seen by the radiologist. In the majority of cases small bowel invasion causes only aspecific symptoms. Gastro-intestinal bleeding is frequently the first specific complaint. Enteroclysis is the most appropriate technique for demonstrating mucosal abnormalities. CT however is not only more sensitive but it also better delineates local and mesenteric involvement.
