Primary Pleural Inflammatory Pseudotumor in a Child

Abstract

Inflammatory pseudo tumor, a rare non-neoplastic lesion, commonly presents as slow growing solid lesion in the lung, but many extra-pulmonary locations have been described. A 4-year-old girl who presented with respiratory distress due to massive pleural effusion. Computed tomography revealed large hypodense non-enhancing lesion in the left hemi thorax. Surgical exploration revealed large semisolid pleural collection filled with gelatinous material with normal underlying lung. Histopathology revealed spindle shaped cells with abundant myxoid stroma. Child recovered after surgery and was asymptomatic at 5 years follow-up. Primary pleural inflammatory pseudotumor may be a rare cause of pleural effusion in a child.
