XXXX as a complication of ultrasound diathermy: a report of eight cases.

@entity1 @entity79 @entity236 @entity2287 @entity130 @entity2530
PURPOSE: To review the magnetic resonance (MR) imaging findings in eight @entity1 who developed @entity236 after undergoing physiotherapy with use of ultrasound diathermy. MATERIALS AND METHODS: The authors retrospectively reviewed the medical charts and MR images of eight @entity1 (six @entity1 and two @entity1 aged 22-69 years) who received ultrasound diathermy treatment for a variety of soft tissue injuries involving primarily the knee, shoulder, and wrist. All @entity1 underwent MR imaging without the use of intravenous @entity2287 -based contrast material. The institutional review board approved the study, and the requirement to obtain informed consent was waived. RESULTS: MR imaging of all @entity1 revealed subcortical rim or arc lesions with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, without involvement of the deeper aspect of the bone marrow. The imaging features of the lesions were similar to those of focal @entity2530 . Follow-up MR imaging performed in three @entity1 approximately 2-3 months after cessation of ultrasound therapy revealed resolution of the @entity79 . Symptoms resolved in all @entity1 . CONCLUSION: This study demonstrated that ultrasound diathermy may produce an @entity130 . The abnormality itself was usually mild and transient, with apparent full recovery after termination of therapy.
