A case of spontaneous, partial, unilateral thrombosis of the corpus cavernosum is described. A 35-year-old white male presented with a painful mass in the perineum without priapism. Diagnostic evaluation with sonography and magnetic resonance imaging revealed a thrombosis in the left posterior corporal body. Treatment consisted of intravenous heparin followed by prophylactic acetylsalicylic acid. The thrombosis resolved spontaneously over several months without sequelae. Conservative management of this rare disease appears to be possible and safe.
A new technique is presented to obtain MR-guided core biopsies of intraosseous lesions of the humeral head. Furthermore, clinical indications of this technique are described.
MR image guided pediatric interventions combine the advantage of an imaging system without ionizing radiation and the high soft-tissue contrast. The low number of these kinds of procedures can be explained by the relatively high costs for the intervention, the increased duration for each procedure and the limited availability of open MRI systems. The integrated localization-system helps during planning of the access path when facing complex anatomical structures and provides safe navigation in sensitive regions like the epiphyseal cartilage. Recent and expected developments of the required MR-compatible biopsy instruments could provide higher efficiency for appropriate sample size and quality. Summarizing, MRI-guided pediatric interventions have shown to be a promising method at the beginning of its development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
