Lumbar plexus neuropathy resulting from retroperitoneal hemorrhage.

A case of lumbar plexus neuropathy occurring in the setting of heparin therapy is reported. Documentation of the site of a retroperitoneal hematoma by CT scan was made prior to the full clinical evolution of lumbar plexus neuropathy resulting from a psoas-muscle hematoma. Two patterns of retroperitoneal bleeding and their respective clinical manifestations are discussed. Early diagnosis of these syndromes may allow for intervention before neurologic compromise is established.

Recognition of unmyelinated fiber disease: morphologic criteria.

An attempt is made to evaluate available information regarding the integrity of unmyelinated fibers, particularly somatic unmyelinated fibers in man and in other primates, with relation to early recognition of nerve disorders. Discussion is limited to morphologic aspects of these fibers.

Probable hypothyroid myopathy: glycogen-deficient type 2b fibers.

Described herein is a case of hypothyroid myopathy with selective atrophy and glycogen depletion of type 2b fibers shown by light and electron microscopy. Although the pathogenesis of such findings is obscure, it is possible that hypothyroidism in conjunction with a superimposed process might explain paradoxically glycogen-deficient fibers.
