CTICasesSaprochaete capitata Pneumonia
Imaging findings
CT chest shows a solitary pulmonary nodule in the right lung that rapidly grew in size over a period of 7 days, associated with small bilateral pleural effusions. The patient has relapsed acute lymphocytic leukemia (ALL) and is severely neutropenic.
Key takeaways
Saprochaete capitata (formerly Geotrichum capitatum or Magnusiomyces capitatus) is a rare, opportunistic yeast that causes severe, invasive infections almost exclusively in profoundly neutropenic patients (such as those with hematologic malignancies like ALL). It carries a very high mortality rate and can present as rapidly growing pulmonary nodules.
