Aspergillus Endogenous Endophthalmitis as a Clue to Identifying a Delayed Lumbosacral Osteomyelitis

PurposeTo present a case of aspergillus-induced endogenous endophthalmitis evolving into delayed lumbosacral osteomyelitis, initially misdiagnosed as ankylosing spondylitis (AS) in an immunocompetent patient.MethodCase Report.ResultsA 38-year-old woman, initially treated for pneumonia, experienced sudden loss of vision in her left eye, prompting a thorough examination that revealed a distinct chorioretinal infiltrate. Microbiological analysis of the patient's vitreous samples detected Aspergillus fumigatus, leading to the diagnosis of endogenous endophthalmitis. Treatment involved vitrectomy, intravitreal injections, and intravenous amphotericin B. Two months later, she was referred for lower back pain, misdiagnosed as AS. Lumbosacral biopsy confirmed Aspergillus involvement once more, necessitating antifungal therapy.ConclusionThis case highlights the atypical progression of Aspergillus-induced endogenous endophthalmitis to delayed lumbosacral osteomyelitis in an immunocompetent individual. It highlights the crucial role of a meticulous medical history examination and interdisciplinary collaboration in diagnosing and managing diseases, especially in cases with atypical presentations.
