Presentation
Pain in left leg, previous DVT.
Patient Data
Age: 75 years
Gender: Male
From the case:
Chronic osteomyelitis - tibia (with sequestrum)
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/84018/annotated_viewer_json?lang=us"}
Well defined intramedullary altered signal intensity lesions measuring approx. 12 x 17 x 79 mm in proximal shaft of left tibia.
Similar lesion measuring approx. 6.7 x 7.3 x 50 mm is seen in distal shaft of left tibia
No evidence of soft tissue component seen. No obvious cortical breach or significant surrounding marrow edema is seen .
Visualized muscles of left leg shows significant reduced bulk with moderate fatty atrophy and hyperintensity.
From the case:
Chronic osteomyelitis - tibia (with sequestrum)
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/84090/annotated_viewer_json?lang=us"}
Corresponding CT cuts show a well defined lesion in proximal shaft of left tibia with a lucent rim and central dense calcification.
Case Discussion
- Well defined intramedullary altered signal intensity lesions in proximal and distal shafts of left tibia. Corresponding CT cuts show well defined lesions in proximal and distal shafts of femur with a lucent rim and central dense calcification consistent with chronic osteomyelitis with sequestrum.
- Reduced bulk with moderate fatty atrophy and hyperintensity of visualized muscles of left leg, possibly related to denervation changes/chronic compartment syndrome.
