Multifocal Post-Traumatic Myositis Ossificans Circumscripta in a Young Male Following a Motor Vehicle Accident: A Review of Imaging and Clinical Presentation.

Traumatic myositis ossificans (MO) circumscripta is an uncommon nonhereditary pathophysiological result of muscular trauma that is detected by radiographic imaging three to four weeks following initial trauma. It is responsible for great global morbidity, with symptoms of prolonged pain, diminished flexibility, and stiffness. There is frequently a delay in diagnosis due to the generalized symptoms and varying radiographic presentation. The goal of therapy is to rule out serious complications (such as soft tissue sarcoma) and to restore strength and range of motion (ROM) as soon as possible. Here we detail the case of a 32-year-old male with a delayed diagnosis of MO who presented to the hospital with left lower extremity pain and swelling following a motor vehicle accident (MVA) that occurred one month prior.

Disseminated Mycobacterium avium Intracellulare Infection With Concurrent Small Bowel Obstruction: Case, Pathophysiology, and Clinical Considerations.

Mycobacterium avium intracellulare (MAI) is an opportunistic infection that typically manifests itself as pulmonary infection. In immunocompromised patients, however, MAI can uncommonly cause disseminated disease and diffuse gastrointestinal involvement. Small bowel obstruction with concurrent MAI infection is rarely documented in literature. Here, a 60-year-old female with a past medical history significant for a gastrointestinal stromal tumor, two small bowel obstructions, and a bowel perforation repair presented to the emergency department with sharp abdominal pain due to a small bowel obstruction. Cultures obtained from the laparoscopic release of small bowel obstruction confirmed the presence of MAI. An antibiotic course of ethambutol, azithromycin, and rifampin was initiated and continued upon transfer to a long-term acute care facility. We describe this case to highlight the possibility of MAI infection in patients with postoperative abdominal pain resulting from small bowel obstruction, review the underlying pathophysiology, and discuss its epidemiology.
