title: MRI findings of intraspinal extradural paragonimiasis granuloma in a child.
abstract: Spinal paragonimiasis is a rare entity. We present a unique case of paragonimiasis involving the extradural space. MR imaging of the thoracic spine showed a bean-shaped extradural mass that extended through the left intervertebral foramen to paravertebral thickened pleura. This finding offers imaging evidence to support the theory that larvae of Paragonimus migrate through perivascular or perineural tissues into the extradural space. Another MRI finding was the hemorrhagic foci in the mass, which occurs frequently in the intracranial paragonimiasis and could also be a feature of the intraspinal paragonimiasis granuloma.
