Empyema necessitatis is a collection of fluid that has, by direct extension from the pleural cavity, penetrated the thoracic wall to form a mass in the extrapleural soft tissues of the chest wall. This is a rare condition and usually is associated with tuberculous effusion but may be associated with malignancy, blastomycosis, actinomycosis, and may even follow thoracentesis.
胸壁寒性脓肿是指胸腔内的液体通过直接蔓延穿透胸壁，在胸壁的胸膜外软组织中形成肿块。这是一种罕见的病症，通常与结核性胸腔积液有关，但也可能与恶性肿瘤、芽生菌病、放线菌病有关，甚至可能继发于胸腔穿刺术后。
