title: Roundworm-associated median nerve compression: a case report.
abstract: Human dirofilariasis is a rare zoonotic infection caused by the bite of a blood-feeding mosquito infected with a filarial nematode (roundworm). these infections can manifest as stationary or migratory subcutaneous or conjunctival nodules. We report an unusual case of Dirofilaria tenuis (D.tenuis) infection that developed into a space- occupying lesion in the wrist leading to median nerve compression pathology in an otherwise healthy young woman. We also comment on the natural history of the disease and report the outcome after surgical excision. To our knowledge, we are the first to report a case of median nerve compression caused by a growing subcutaneous nodule from a D.tenuis infection.
