Pulmonary, liver and cerebral paragonimiasis: An unusual clinical case in Colombia
TRAVEL MEDICINE AND INFECTIOUS DISEASE(2022)
摘要
Background: Mainly affecting poorer populations in remote (sub)tropical areas, paragonimiasis is considered one of the world's most neglected tropical diseases by the World Health Organization. It is usually acquired by consuming undercooked freshwater crustaceans and primarily affects the lungs, but may ectopically migrate to other organs to produce a multisystemic clinical presentation. This study details what appears to be the first documented case in South America and particularly in Colombia of cerebral paragonimiasis and infection by the crab Moreirocarcinus emarginatus. Case presentation: After consuming this crab, a 32-year-old Colombian male developed dyspnea and headache. A chest X-ray revealed tension pneumothorax (TPT) and a thoracoscopic lung biopsy bronchiolitis, eosinophilia, and granulomatous reaction due to Paragonimus parasites. Results: Brain tomography and MRI also showed a configuration typical of Paragonimus parasites, namely a predominantly cystic area near the left cuneus with diffusion restriction, a hemosiderin halo, and linear enhancement characteristic of the tunnel sign, indicating an adult worm moving in the brain. Conclusions: Cerebral paragonimiasis can occur in the Colombian population and Moreirocarcinus emarginatus can be its cause. In rural areas, education about raw crab consumption would be beneficial, and physicians addressing lung-related complaints should bear paragonimiasis in mind and ask about raw crab consumption.
