Follow-Up MR Imaging for Cerebral Sparganosis.

The recent article on follow-up MR imaging for cerebral sparganosis is interesting. Li et al noted, “Migration is a notable feature of cerebral sparganosis.” This finding is quite interesting. Due to its basic nature, sparganosis is usually a chronic localized disease. According to a large series from Thailand, no observation of cerebral migration was noted. The “tunnel” sign is a new finding that was recently reported, but there has been no confirmation on pathology. The question is whether the cases are actual sparganosis with confirmed pathology or whether there is any additional co-occurrence of another migrating cerebral parasitic disease such as gnathostomiasis.
