Ultrastructural modifications of muscle in three types of compartment syndrome.
The histological and ultrastructural aspects of three cases representing different types of compartment syndromes are analyzed. In the acute syndrome edema is the prominent feature. The two chronic cases are characterized by an accumulation of intermyofibrillar lipid globules. All three have in common mitochondrial enlargement, disorganization of the cristae and paracrystalline inclusions. These pathological findings are discussed in the light of lesions seen in striated muscle ischaemia or in certain metabolic myopathies.
