Cavitary pulmonary coccidioidomycosis is rare diagnosis with an incidence of 13% to 15% of pulmonary coccidioidomycosis cases. High clinical suspicion is necessary in the setting of geographical location endemicity. We present a 49-year-old male who has lived in the Coachella Valley of California for several years, with a medical history of uncontrolled type 2 diabetes who noted 1 week of right-sided chest pain with shortness of breath, fever, chills, night sweats, and weight loss. A chest X-ray revealed a 4- to 5-cm mass in the right lung. Initial workup revealed negative sputum cultures (aerobic/anaerobic, acid-fast bacilli). However, dedicated fungal cultures (samples from sputum, lymph nodes, lung right lower lobe bronchial swabs), bronchial washings, and surgical tissue biopsy of the right lower lobe revealed mold. The patient underwent right thoracotomy with right lower lobectomy and right mediastinal lymph node dissection for both diagnostic (lung specimen) and therapeutic (removing necrotic lung tissue, source control) purposes. Finally, serum Coccidioides antigens were positive and antibody titers were positive at 1:8; surgical biopsy of the right lower lobe grew mold that came back positive for Coccidioides posadasii . Targeted pharmacotherapy was commenced using intravenous fluconazole and then oral fluconazole for 3 months was prescribed upon discharge. The patient had gradual improvement of his shortness of breath and was instructed to follow-up at an infectious disease clinic.
