Myositis, while uncommon, develops more frequently in patients with human immunodeficiency virus infection. We report a case of acute lower leg ischemia caused by myositis in such a patient. Urgent four-compartment fasciotomy of the lower leg was performed, which decompressed the compartmental hypertension and reversed the arterial ischemia. This case underscores the importance of recognizing compartment syndrome as a cause of acute limb ischemia.

Four children are described who developed focal lower limb nerve palsies following critical illness. Two had clinical and/or neurophysiological evidence of simultaneous generalised critical illness polyneuropathy. The diagnosis was delayed in three patients due to the presence of central motor abnormalities and slow motor recovery. Follow-up from seven months to three years showed minimal or no recovery. In three, a vasculitic skin infarct, compartment syndrome and focal myositis could have caused nerve compression. We suggest that in critical illness peripheral nerves have an increased susceptibility to damage by local pressure.

Hamstring injuries can be classified with regard to the site of involvement. Traumatic disorders at the proximal bone-tendon origin are best defined as avulsion injuries, such as ischial tuberosity fractures and hamstring tendon tears. Musculotendinous lesions include muscle strains and muscle contusions. Most hamstring injuries occur after in-direct trauma from excessive stretching or forceful contraction, leading to avulsion injuries or muscle strains and tears. Insufficient warm-up, lack of flexibility, inadequate muscle strength and endurance, or abnormal contraction and running may predispose to such injuries. In the event of blunt direct trauma, a muscle contusion, intramuscular hematoma, myositis ossificans, or compartment syndrome may develop.

While most muscle injuries are recognized clinically, magnetic resonance imaging (MRI) is the ideal noninvasive test to assess their extent and severity, which impacts therapy and influences prognosis. Typical examples of these injuries include muscle contusions, lacerations, sprains, and delayed onset muscle soreness. For other less common traumatic muscle conditions (exertional compartment syndrome, muscle herniation, and traumatic denervation), the clinical findings are often subtle or ambiguous and MRI will indicate the correct diagnosis. In patients with known muscle trauma, MRI can detect complications such as hematoma or seroma development, scarring and fibrosis, and myositis ossificans. This article illustrates the spectrum of muscle injuries, emphasizing the value of MRI in their diagnosis.

Acute compartment syndrome of an extremity poses a threat to both life and limb. The usual cause in children is trauma, especially fractures and burns. Two recent cases of nontraumatic compartment syndrome of the extremities in children are presented, both owing to infection followed by myositis or fasciitis. Both cases required urgent decompression by fasciotomy, resulting in limb salvage and full recovery of neuromuscular function of the extremity. The value of prompt recognition and treatment of this condition is emphasized.

Compartment syndrome has rarely been reported associated with acute rhabdomyolysis. In the case described, the rhabdomyolysis was severe enough to cause compartment syndrome and acute renal failure after moderate exercise and alcohol intake and had the appearance of a myositis. The case emphasizes the importance of early recognition of compartment syndrome, as loss of pulses is a very late sign, and the examination of the urine to detect myoglobinuria in rhabdomyolysis. Measurement of creatine kinase is predictive of the extent of muscle damage and the development of renal failure.

Compartment syndrome as a result of simvastatin-induced myositis is extremely rare. This case discusses a patient with spontaneous onset compartment syndrome that necessitated four-compartment fasciotomy. A thorough investigation into its cause highlighted statin-induced myositis as the most likely aetiological agent. When investigating a patient with unexplained spontaneous compartment syndrome it is important to consider drug-induced myositis. This case reinforces the difficulty faced in diagnosing spontaneous compartment syndrome.

This case report discusses a 43-year-old man who presented with 4-limb compartment syndrome secondary to influenza A myositis. We describe the clinical features that were present and the course of this unusual complication. We review the clinical features central to early diagnosis and treatment of compartment syndrome in order to increase awareness of this potentially life-threatening complication.

Myositis ossificans is a benign disorder of heterotopic bone formation occurring in response to soft tissue trauma. It most commonly presents in young adults and children as a painful, enlarging mass of the arm or thigh. Since there is frequently no significant history of injury, the lesion may be mistaken for a malignant bone or soft tissue tumor or infection. This article presents a case of a child in whom myositis ossificans presented with local signs and symptoms suggestive of a rapidly progressive compartment syndrome following trauma.

A previously fit and healthy 8-year-old boy died following severe complications of influenza A. He developed lethargy and vomiting before presentation. On presentation to medical attention, on day 4 of his illness, he was in extremis and had extensive myositis, rhabdomyolysis, renal failure and compartment syndrome, which were resistant to supportive medical management.
