Back in March, my mother was diagnosed with pulmonary sarcoidosis.

早在三月份，我的母亲就被诊断出患有肺结节。

Sarcoidosis is another cause that involves the formation of granulomas in the heart tissue, which are these collections of immune cells.

结节是，组织中肉芽肿形成导致限，这些肉芽肿是免疫细胞的聚集。

Intra-hepatic causes include cirrhosis, schistosomiasis, which is when flatworms invade the liver; and sarcoidosis, which is when inflammatory cells form lumps called Granulomas inside the liver.

肝内型包括肝硬化、血吸虫（当种血吸虫侵犯肝时），还有结节，种炎性细胞在肝内形成肉芽肿的疾。
