We present a case of a 78-year-old female who developed persistent neurological complications following a concurrent dengue and chikungunya viral infection. The patient experienced progressive weakness and ambulatory difficulties, culminating in left foot drop. This case highlights the potential long-term neurological sequelae of these tropical viral infections and emphasizes the importance of considering a post-viral vasculitis-like presentation in patients with delayed neurological symptoms.
