Introduction:

Pulmonary paragonimiasis is an uncommon tropical trematode infection caused by Paragonimus spp. Acquired through the intake of freshwater crabs, this condition is characterized by respiratory symptoms such as chronic coughing and rusty expectoration. Pleural effusion is a rare complication accompanied by dyspnea and difficulty breathing.

Objective:

Describe a case of bilateral pleural effusion due to Paragonimus spp. infection.

Clinical case:

A female 51-year-old indigenous Kichwa woman was admitted for difficulty breathing and progressive dyspnea, coughing and hemoptoic expectoration. Chest radiography and computed axial tomography showed bilateral pleural effusion, whereas Paragonimus spp. eggs were visible in sputum samples under the microscope. Praziquantel 1 800 mg/day was administered for three days. The patient was discharged on the fifth day and at 45 days the respiratory picture and the pleural effusion were found to have resolved.

Conclusions:

Consideration should be given to the search for eggs of the parasite in sputum and/or pleural fluid of patients with respiratory symptoms and pleural effusion, even if they are migrants from endemic countries, with a view to an early diagnosis and timely treatment.
