Summary

Cerebral sparganosis, a rare parasitic brain infection, presents unique CT scan findings. These include unilateral white matter lesions, enhancement, and calcification, indicating inflammation and degeneration.

Area of Science:

  • Neurology
  • Parasitology
  • Radiology

Background:

  • Cerebral sparganosis is an extremely rare parasitic zoonosis.
  • It is caused by migrating plerocercoid larvae of the genus Spirometra.

Purpose of the Study:

  • To retrospectively analyze computed tomography (CT) scan characteristics of cerebral sparganosis.
  • To correlate imaging findings with clinical and pathological data.

Main Methods:

  • Retrospective analysis of 19 CT scans from 12 patients with cerebral sparganosis.
  • Correlation of CT findings with available clinical and pathological information.

Main Results:

  • CT findings included unilateral involvement, extensive white matter low-density areas, ipsilateral ventricular dilatation, and cortical atrophy.

  • Nodular or irregular enhancement with spotty calcification was observed.
  • Sequential scans showed changes in the location of enhancing nodules.

    • Conclusions:

    • The observed CT features are pathognomonic for cerebral sparganosis.
    • These findings reflect a chronic inflammatory process with granulomatous lesions and widespread white matter degeneration.
    • Larval migration along white matter tracts likely causes the observed degeneration.
