• Pleural cryptococcosis
• thoracoscopic surgery

Pulmonary cryptococcosis is most likely to occur in immunocompromised patients. The radiological manifestations generally include pulmonary parenchymal lesions, namely, pulmonary nodules, cavitary lesions, and consolidation; thus, multiple pleural nodules are unusual presentation. Here, we report a woman who presented with multiple pleural cryptococcosis without pleural effusion. The patient had previously undergone surgery for stage II rectal cancer. In addition, she received 6 cycles of chemotherapy for follicular lymphoma. Computed tomography (CT) revealed multiple small nodules involving the pleura without pleural effusion, which suggested possible recurrence of rectal cancer or malignant lymphoma as pleural dissemination. Thoracoscopic examination was performed, and pleural cryptococcosis was diagnosed. Although pleural cryptococcosis without pleural effusion is extremely rare presentation, clinicians should consider it when an immunocompromised patient presents with multiple pleural nodules. Thoracoscopic exploration should be the best procedure for the definitive diagnosis of multiple pleural nodules.
