ABSTRACT
BACKGROUND: Angiolipomas are rare benign tumors, accounting for 0.14% to 1.2% of all tumors of the spinal axis with vascular and fatty histological features. Spinal angiolipoma (SAL) is most commonly found in the thoracic region and has high signal on contrast enhanced fat-saturated T1-weighted imaging. Although the international literature is extensive, there are few cases reported in United States. OBJECTIVE: To present a case of SAL located in the thoracolumbar region without high signal on contrast enhanced fat-saturated T1-weighted imaging and to review previously reported cases. STUDY DESIGN/METHODS: Case report and review the literature. RESULTS: Magnetic resonance imaging obtained in a 68-year-old man with a long history of lumbago showed a heterogeneous mass (T10-L1) hyperintense on T1-weighted imaging but not enhancing on suppression fat sequences, suggesting epidural hematoma. Surgical excision of the lesion was performed, and SAL was diagnosed and confirmed by pathology. The patient became asymptomatic. CONCLUSIONS: The predominance of either vascular or fatty components inside the tumor might alter the expected results on magnetic resonance imaging with suppression fat sequences.

One of the most serious potential complications of vertebroplasty or kyphoplasty is the embolization of methylmethacrylate cement into the pulmonary arteries. We present an overview of the subject and a pictorial review the spectrum of radiographic and computed tomographic appearances of methylmethacrylate cement pulmonary emboli.

Computed tomography (CT) is often the first modality ordered in patients with suspected bowel obstruction. Three-dimensional (3D) CT imaging is now seen as a valuable tool for illustrating pathologic findings to clinicians and surgeons. Three cases are reported in which 3D CT volume rendering was used to demonstrate transition points in proximal small bowel obstructions in patients who had received oral contrast.

Chondrolipoma is a rare form of benign mesenchymoma. We report the case of a chondrolipoma in the palm of a 9-year-old boy with corresponding sonographic, magnetic resonance (MR) and pathological findings.

We report a case of testicular torsion in the left inguinal canal of a 7 month old with a history of cryptorchism and no evidence of neuromuscular disease. We discuss the pathophysiological mechanisms, sonographic findings, and treatment of this rare entity.
