“…Our patient, however, was negative for ANA and dermatological findings (Gottron’s sign, mechanic hand sign, and shawl sign), effectively excluding this disease. Similarly, Mahgoub et al also reported a case of immunoglobulin G4 disease associated with EPE [18]. However, the clinical and laboratory findings in that case was not similar to ours.…”

A pleural effusion is defined to be eosinophilic when 10% or more of the white blood cells in pleural fluid are eosinophils. Despite the multitude of studies enumerating the causes of eosinophilic pleural effusion (EPE), 14%-25% of such cases remain idiopathic even after thorough work-up. We report a case report of a 28-year-old never smoker male from the Rukum district of Nepal who presented to the emergency department (ED) with a chief complaint of shortness of breath associated with a low grade fever, nonproductive cough, and pleuritic right-sided chest pain for two weeks. There was no past medical and surgical history of note. Clinical examination revealed findings suggestive of a right-sided pleural effusion and relevant laboratory and radiological investigations were performed. Symptomatic treatment for the fever was administered. Full blood count showed a leukocytosis of 34 × 10 9 /L with an absolute eosinophil count (AEC) of 7.5 × 10 9 /L (22%). Peripheral blood smear showed normocytic normochromic erythrocytes with eosinophilia (morphologically normal eosinophils). Autoimmune profile was normal, inflammatory markers including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were raised, and an ultrasound and a plain radiograph of the chest confirmed the right-sided pleural effusion. Empirical anti-helminthic coverage was instituted. Subsequent infectious disease work-up was negative. An ultrasound-guided thoracentesis was performed, and the straw-colored pleural fluid showed an exudative picture which was eosinophil-predominant (42%). No malignant cells were detected. Failure of response to anti-helminthic therapy for one week led the team to start oral prednisolone 1 mg/kg once daily with the dose tapered subsequently. The patient responded dramatically. This was continued for one week and a regression of pleural effusion was demonstrated on chest radiography with a normalization of inflammatory parameters (ESR and CRP) and peripheral blood counts. Outpatient follow-up after one month showed no remaining clinical and radiological signs of EPE, and the peripheral eosinophilia resolved. As far as we know, this is the first case report of idiopathic EPE in the context of Asia. There are many causes of EPE, and some of them are still being discovered.
