Proliferative myositis: case report and review of the literature

Proliferative Myositis in the Upper Extremity: Vaccination-Induced Pathology?

“…MRI is often done for further evaluation. Axial fluidsensitive sequences show a similar pattern as seen in ultrasound in which the hyperintense bands represent inflammatory infiltration [1,2].…”

“…Postcontrast T1WI showed a marked enhancement (Figures 2, 3, 4). The 'cracked dry mud' pattern seen on US is also demonstrated on axial fluid-sensitive sequences (Figures 3, 4) [1,2].…”

“…It is mostly seen in middle-aged people. The muscles of the trunk, upper extremities, head, and neck are most often affected [1,2].…”

“…It is a benign, selflimiting pathology; hence no specific therapy is needed. A wait-and-see approach with follow-up imaging is recommended, but a biopsy is often performed to rule out malignancy [1,3].…”

Occurrence of proliferative myositis after COVID-19 vaccination: A case report

The authors suggested that unknown mechanisms might have contributed to the inflammatory process in addition to minor muscle injury from injection [10] . However, in the other 2 reported cases, the myositis was systemic [11] .…”
