A 53-year-old female had complained of pain and knee restriction after surgical treatment of a knee tumor at the age of 31. The details of surgical treatment were unclear. Axial T1-weighted MRI revealed low signal with fat component and sagittal fat-saturated T2-weighted MRI revealed high signal intensity (Fig. e, f). Under the clinical diagnosis of atypical lipomatous tumor or high grade liposarcoma, needle biopsy was performed, and the diagnosis of angiomatosis was made. Then, surgical resection was performed. After the resection, knee restriction disappeared.
A 29-year-old female patient had complained of discomfort and mild pain in the left shoulder since she was 18-year-old. After childbirth, she had severe ongoing pain and contracture of the shoulder. She had no significant prior medical or surgical history. Axial fat-saturated T2-weighted MRI revealed high signal intensity and sagittal T1-weighted MRI revealed low signal intensity within the muscle of the shoulder. (Fig. c, d). Under clinical diagnosis of VM, the lesion was resected.
