Unusual manifestation of pulmonary Verruconis gallopava infection with synchronous reactive pericardial effusion in a non-transplanted patient.

Verruconis gallopava is an emerging causative agent in solid organ transplant patients, increasing in prevalence both in non-transplanted patients and also in immunocompetent ones, albeit rarely. In this case report, we describe an unusual V. gallopava infection in a patient with steroid-dependent autoimmune haemolytic anaemia. The chest CT scan revealed a mass-like consolidation in the superior segment of the right lower lobe, and bronchoscopic examination confirmed V. gallopava from bronchoalveolar lavage. The histopathology showed non-necrotising granulomatous inflammation concurrent with septate-pigmented hyphae, which is compatible with dematiaceous fungi. After 3 weeks of posaconazole treatment, the patient developed a new pericardial effusion. Further investigations, including culture, cytology and histopathology, yielded negative results, leading to suspicion of reactive pericardial effusion associated with V. gallopava pulmonary infection. The patient received antifungal therapy for 9 months, after which a follow-up chest CT scan showed complete resolution of consolidation and pericardial effusion.
