Abstract

1-year-old girl was admitted for fever of unknown origin. Funduscopy revealed juxtapapillary retinal inflammatory mass in one eye with a differential diagnosis of sarcoidosis, tuberculosis, retinoblastoma or metastatic disease. Retinal biopsy showed necrotizing granulomatous retinitis. Extensive workup and therapeutic trials failed to confirm the diagnosis of tuberculosis or sarcoidosis. Her 7-month brother and 4-year-old male cousin presented with nystagmus, poor vision, paravascular pigmentary changes and were initially diagnosed as recessive retinal dystrophy. The girl died at age 2 from tuberculous meningitis and the boys had recurrent tuberculous and Aspergillus infections. Awareness of the typical fundus findings in chronic granulomatous disease allows early diagnosis of the disorder.

Case presentation

This 1-year-old girl with high fever (40°C) of unknown origin had a juxtapapillary multinodular 4 disc diameter vascular inflammatory mass with exudative retinal detachment in the left eye (fig. 1). Diagnostic tests and therapeutic trials failed to confirm the diagnosis of tuberculosis or sarcoidosis, with retinal biopsy done to rule out retinoblastoma (fig. 2) showing necrotizing granulomatous disease of unknown etiology (negative stains for mycobacteria). Her 7-month brother and 4-year-old male cousin presented with nystagmus, poor vision, paravascular pigmentary changes (fig. 3) and were diagnosed as recessive retinal dystrophy as the parents were first-degree cousins. The girl died at age 2 from tuberculous meningitis and the boys had recurrent tuberculous and Aspergillus infections.

Discussion

Chronic granulomatous disease is a syndrome that presents as pneumonia, infectious dermatitis, and recurrent abscess formation beneath the skin and in multiple organs, including the eye [1]. Tissue examination typically shows microscopic granulomas [2]. There is a recent shift in the most common infecting organisms away from staphylococci and enteric bacteria to Aspergillus species [1]. At the cell level, neutrophils and macrophages phagocytose but do not kill all organisms effectively as the NADPH oxidase complex does not convert oxygen effectively to microbicidal oxidants.

Around 76% of patients had the X-linked recessive form of chronic granulomatous disease [1]. Chorioretinitis may be more common than previously appreciated (23.7% [3] vs. 35.3% [4]), and boys with the XLR disease should have routine full eye exams. Fig. 3 displays the typical "punched out" chorioretinal lesions with pigment clumping along major retinal vessels (that may interfere with vision) seen in up to one third of patients with chronic granulomatous disease [3, 4]. Occasionally the presentation is that of a retinal mass [5] as in the present case. Chronic granulomatous disease needs to be included in the differential of inflammatory retinal mass and the clue lies in family screening for paravascular pigmentary retinopathy.
