Pulmonary cavitation is a well recognized feature of adult pulmonary tuberculosis, but the presence of fluid levels in the cavities has been considered unusual. However, in 550 cases of proven pulmonary tuberculosis in a rural Nigerian population, 257 cases had cavitation, and fluid levels occurred in 56 of the cavities (21%). Positive Ziehl-Nelson sputum stain was more frequent in patients with cavitation and fluid levels: Sputum tests were positive in 69% of those with cavitation and fluid levels, 48% of those with cavitation but no fluid levels, and in 30% without cavitation.
肺空洞形成是成人肺结核的一个公认特征，但空洞内出现液平一直被认为不常见。然而，在尼日利亚农村地区确诊的550例肺结核病例中，257例有空洞形成，其中56个空洞（21%）出现了液平。有空洞并伴有液平的患者痰涂片抗酸染色阳性更为常见：痰检在有空洞并伴有液平的患者中69%呈阳性，在有空洞但无液平的患者中48%呈阳性，在无空洞的患者中30%呈阳性。
