[Post-traumatic inflammatory pseudotumor of the lung. Description of a case]

Inflammatory pseudotumor (P.I.) of the lung is a rare benign lesion histologically characterized by a variety of inflammatory and mesenchymal cells (plasma cells, lymphocytes and histiocytes). The etiology remains obscure. We report a case of P.I. occurred immediately after a thoracic trauma. The infectious etiology is suggested by the growth of an anaerobic microorganism (Bacteroides) in tissue culture.
