Phaeohyphomycosis caused by Trematosphaeria grisea in an immunocompromised English springer spaniel
A 10‐year‐old, male, farm‐based springer spaniel that presented with subacute progressive left‐sided central vestibular signs was diagnosed with meningoencephalitis of unknown origin. The patient received prednisolone (2 mg/kg/day orally), ciclosporin (5 mg/kg orally twice a day) and a single infusion of cytarabine (200 mg/m2). Six weeks later, neurological signs had resolved, but multiple cutaneous nodules developed on the limbs, trunk and face. Lesions discharged a dark purulent material without tissue grains. A ‘filamentous fungus’ was isolated, but discarded without identification. Aspirates from nodules showed pigmented, septate fungal hyphae, and culture of aspirates yielded Trematosphaeria grisea. Itraconazole (5 mg/kg once a day) and gradual tapering of immunosuppressive drugs led to resolution of nodular lesions over 4 months without neurological relapse. A fungal granuloma developed transiently 8 months after starting itraconazole. Immunosuppressive drugs were stopped 15 months after introduction without neurological relapse. Itraconazole was withdrawn 8 weeks later, 5 months after last relapse of skin disease.
期刊介绍:
Vet Record Case Reports is an online resource that publishes articles in all fields of veterinary medicine and surgery so that veterinary professionals, researchers and others can easily find important information on both common and rare conditions. Articles may be about a single animal, herd, flock or other group of animals managed together. Common cases that present a diagnostic, ethical or management challenge, or that highlight aspects of mechanisms of injury, pharmacology or histopathology are deemed of particular educational value. All articles are peer reviewed and copy edited before publication.
