Abstract:
We report a 74-year-old woman with cervical cancer who developed pulmonary cryptococcosis which presented as a solitary focal ground-glass opacity (GGO) on high-resolution computed tomography (HRCT). Serial HRCT showed the progression from the GGO to a discrete solid nodule. We hypothesize that the initial GGO may correspond pathologically to partial filling of air spaces with cryptococcal organisms and inflammatory cells. To our knowledge, this is the first report of pulmonary cryptococcosis with a solitary focal GGO on HRCT in the literature.
