Positron emission tomographycomputed tomography scan demonstrating fluorodeoxyglucose-avid nodule in the left upper lobe.Figure 1. Computed tomography of your lung revealing the nodule of four mm (A) with fast development to 9 mm (B) within a 3-month period with no other nodules, infiltrates, or lymphadenopathy.A 74-year-old man with stage IV mantle cell THBS1, Human (HEK293, His) lymphoma was referred for any gradually enlarging solitary pulmonary nodule noted on imaging. Prior therapy for his lymphoma incorporated rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone, and bortezomib. Despite the fact that he had not received any of those therapies for 3.five years, he had been receiving ibrutinib therapy for the prior 5 months. He denied any respiratory or constitutional symptoms. He had a remote smoking history but no pets or current travel. His hobbies integrated walking inside the park and performing yardwork. Physical examination was unremarkable. Computed tomography (CT) of his chest revealed a 9-mm nodule (Figure 1) within the left upper lobe that had increased from four mm on imaging from three months prior, but no other infiltrates or lymphadenopathy had been noted. Constructive emission tomography T scan demonstrated uptake inside the nodule having a standardized uptake worth of 3.1 (Figure 2). Laboratory data revealed a white blood cell count of two.six K/ml, with 47 neutrophils, 33 lymphocytes, 18 monocytes, 1 eosinophils, and 1 basophils. CT-guided biopsy of your lesion revealed lung parenchyma with many organisms compatible with LIF, Human Cryptococcus (Figure 3), but culture of tissue remained unfavorable. Lumbar puncture and serum cryptococcal antigen and HIV antibody had been damaging. The patient was treated with fluconazole. Repeat imaging 4 months later revealed a slight reduce inside the nodule, and repeat positive emission tomography T scan five months later demonstrated a stable nodule with a lowered standardized uptake value of 2.four. Cryptococcal infections have been most normally reported in individuals with HIV, but, immediately after excluding those, malignancy was the underlying danger element in five to 27 of cryptococcal infections (1). The predominant malignancies reported with cryptococcal infections are hematologic, particularly lymphoma. Two large series have reported invasive fungal infection with Cryptococcus in 1.five to 2.eight of hematologic malignancies (1).
