Multimodal imaging of an acute presentation of ocular histoplasmosis syndrome in an immunocompetent patient
© 2023 Published by Elsevier Inc..
Purpose: Presumed ocular histoplasmosis syndrome (POHS) is a posterior segment disorder that is usually subclinical unless choroidal neovascular membrane (CNVM) develops. It is thought to be the sequela of a prior systemic infection with Histoplasma capsulatum, and evidence supporting this association is based on epidemiologic, animal, and few enucleation studies. Acute presentation of chorioretinal involvement during an initial histoplasmosis systemic infection in immunocompetent patients is rarely reported, presumably due to the usual lack of or minimal symptoms of both the systemic and ocular disease. We report on an immunocompetent male with choroidal lesions detected during disseminated histoplasmosis infection and characterize the lesions using multimodal imaging.
Observations: A 17-year-old male presented when routine optometry screening detected two deep, yellowish-white lesions in the left fundus. Optical coherence tomography (OCT) imaging confirmed a choroidal mass with extension through Bruch's membrane into the subretinal space and a small amount of subretinal fluid. Fluorescein angiography was suggestive of CNVM. There were no clinical findings of intraocular inflammation, and the patient was initially lost to follow-up. Eight weeks after last follow-up, the patient presented to the emergency department with fatigue, mild respiratory symptoms, and abdominal pain for the last month. Imaging revealed a mediastinal mass with hilar extension and innumerable nodules throughout the lung and spleen. Serum Histoplasma IgM/IgG were positive, and biopsy of the mediastinal mass revealed Histoplasma organisms. The patient was treated with antifungals and discharged. The patient underwent an extensive immunologic evaluation while admitted, which did not reveal an underlying immunodeficiency. On last follow-up, the choroidal lesions were smaller and more consolidated, and the subretinal fluid had resolved.
Conclusions and Importance: We present a patient with choroidal lesions in the setting of disseminated systemic histoplasmosis infection and characterize a lesion using multimodal imaging. The presentation of acute chorioretinal lesions in the setting of biopsy proven systemic Histoplasma infection supports H. capsulatum as the etiology of POHS.
