We present two cases of pulmonary aspergillosis in which calcium oxalate crystals in the sputum proved to be a useful diagnostic clue. In case 1, Aspergillus hyphae was not identified; however, calcium oxalate crystals were present, and chronic necrotizing pulmonary aspergillosis was diagnosed. In case 2, calcium oxalate was detected and Aspergillus fumigatus was identified later. Thus, the presence of calcium oxalate in the sputum may be an important indicator for an A. fumigatus infection.
我们报告了两例肺曲霉病病例，其中痰液中的草酸钙晶体被证明是一个有用的诊断线索。在病例1中，未发现曲霉菌丝；然而，存在草酸钙晶体，并诊断为慢性坏死性肺曲霉病。在病例2中，检测到草酸钙，后来鉴定出烟曲霉。因此，痰液中草酸钙的存在可能是烟曲霉感染的一个重要指标。
