We report a case of primary pulmonary cryptococcosis. A 20-year-old woman was admitted to the hospital complaining of coughing, fever, and dyspnea on exertion. She had no underling disease or immunological abnormality. Chest X-ray film revealed bilateral diffuse infiltrative shadows, which were first believed to have been caused by a community-acquired pneumonia. Pulmonary cryptococcosis was diagnosed from the results of a transbronchial lung biopsy. After 2.5 years of anti-mycotic chemotherapy with amphotericin B and flucytosine, pneumothorax occurred in the left lung. Thoracotomy and open lung biopsy were done. Histological findings of the open lung biopsy specimens showed numerous broken cryptococcal organisms within alveolar macrophages. Diffuse fibrosis accompanied by multiple bullae may have punctured bullae or blebs and thus led to pneumothorax.

An 81-year-old man being treated with weekly low dose methotrexate (MTX) for psoriasis was admitted with a 2-month history of cough, shortness of breath and 7% eosinophilia in the peripheral blood. Chest roentgenogram revealed bilateral alveolar and interstitial infiltrates. Although the clinical presentation suggested MTX pneumonitis, a transbronchial lung biopsy established a diagnosis of pulmonary cryptococcosis. Pulmonary cryptococcosis should be included in the list of infectious processes that can mimic MTX pneumonitis.

During the 7 years from 1990, thirty-two patients (20 in male and 12 in female, mean age; 53 years old) were diagnosed as having pulmonary cryptococcosis. To clarify the essential points for early diagnosis of pulmonary cryptococcosis, we reviewed the clinical records and chest images. Three patients had a past history of pulmonary tuberculosis and eleven patients had underlying disorders such as malignancy, chronic pulmonary diseases and so on, but no HIV infection, which would affect this disease. Eighteen patients did not have any past history nor complications. The symptoms such as cough, sputum, chest pain and fever were generally of low-grade, 14 patients had no symptom at diagnosis. Except of some patients with severe infections and severe underlying disorders, laboratory findings such as inflamatory and nutritious markers were almost within near the normal range. On plain chest X-ray films the distribution of lesions was almost in proprtion to the volume of the lobes. The multifocal nudular and/or infitrative shadows wer observed in about 2/3 cases and single lesion in about 1/3. The width of lesions were minimal except of one case with interstitial pneumonia and two cases with multifocal segmental pneumonia. The cavity lesions were observed in 7 cases and hilar lymphadenopathy in 3 cases. On CT images, the lesions were almost located in the outer zone, the lesions which were adjacent to the pleura were observed in 15 cases. Cavitary lesions were almost smooth in edge and ubiquitous, the walls were also thick. The peripheral air-bronchogram in the nodular/infitrative shadows were observed in three cases. Pulmonary cryptococcosis is air-borne and almost a chronic infection except in AIDS patients, so careful planning for examination is essential with considerations of the characteristics of clinical and imaging features of this infection.

Pulmonary cryptococcosis is a very rare form of pneumonia, which is seldom seen among immunocompetent patients. We report the case of a 36-year-old man who presented with indolent pneumonia that was subsequently diagnosed to be pulmonary cryptococcosis without other systemic involvement. Contrary to formal belief, there was evidence of residual lung fibrosis 12 months after initial presentation. The features of pulmonary cryptococcosis reported in the Asian Pacific region are also reviewed.

A 31-year-old male was admitted to Toranomon Hospital because of a cough and bilateral patchy infiltrates shown on the chest radiograph. He had been well prior to admission. Chest CT scan revealed patchy areas of air-space consolidation with air-bronchogram and adjacent ground-glass opacities, suggestive of bronchiolitis obliterans organizing pneumonia (BOOP). Transbronchial lung biopsy specimen confirmed the formation of epithelioid cell granulomas without necrosis and the coexistence of organizing pneumonia. The titer of serum cryptococcal antigen increased to 1:256. According to these findings, a diagnosis of primary pulmonary cryptococcosis was made, although cryptococci were neither recognized in the specimen nor cultured from the bronchial lavaged fluid. Chest radiograph showed spontaneous regression in a short period of time. However, itraconazole was administered for the prolonged cough, and the symptom disappeared. The titer of serum cryptococcal antigen decreased to 1:16 after the therapy. Pulmonary cryptococcosis should be considered as one of the differential diagnoses when chest CT scan shows combined air-space consolidation and ground-glass opacities.

Pulmonary cryptococcosis is the consequence of the inhalation of Cryptococcus neoformans, an encapsulated yeast, from various environmental sources. It is commonly accepted that the acquisition of the disease occurs early in life and that the disease is mostly related to a reactivation from a pulmonary site in immunocompromised hosts such as patients infected with human immunodeficiency virus. Clinical and radiological presentations of the disease are nonspecific and are more severe in immunocompromised hosts with acquired immunodeficiency syndrome (AIDS). However, fulminant forms have also been reported in apparently immunocompetent hosts. C. neoformans has rarely been responsible for colonization of the respiratory tract; this usually occurs in immunocompetent hosts with preexisting pulmonary disease. Diagnosis of pneumonia is obtained by either analysis of bronchoalveolar lavage in AIDS patients or by the histology/mycological analysis of a pulmonary nodule. In any case, a careful work-up for diagnosing dissemination should always be performed. Antifungal treatment has to be given in most of the immunocompetent hosts and always in those with any kind of immunodeficiency with isolated pulmonary cryptococcosis.

Pulmonary cryptococcosis is an unusual fungal infection that is most often found in AIDS or in organ transplant recipients. Although in immunocompromised patients, cryptococcal infection often causes pulmonary infections, the diagnosis of lung involvement is generally difficult. The presentation of pulmonary cryptoccosis in HIV-infected patients appears to be more acute and severe than in other immunocompromised patients, probably related with the severe immunosuppression. Diffuse infiltrates, mediastinal and hilar lymph nodes enlargement are the most common radiological findings in AIDS-associated pulmonary cryptococcosis. Cavitation is a rare form of and includes only 10% to 15% of all cases. Only a few case reports or studies with small number of patients of pulmonary cryptococcosis have been published over the past two decades. We report a case of an AIDS patient who developed cavitary pneumonia as the only clinical expression of cryptococcosis.

Pulmonary cryptococcosis is rare in immunocompetent subjects. Here, we present the case of a 16-year-old boy who was referred to our pediatric department for the management of multiple consolidations detected on chest radiography, which was routinely performed when the patient was being evaluated for an ankle fracture. Fine needle aspiration biopsy was performed, and the definitive diagnosis was established as cryptococcal pneumonia. After 8 weeks of antifungal treatment, the pulmonary nodules on the chest radiographs disappeared.
