Lacrimal Gland Abscess: A Case Report
Abstract
Introduction: The aim of the study was to report a rare case of lacrimal gland abscess. Case Presentation: A 47-year-old woman noticed upper eyelid swelling on the right side 1.5 months before referral to our service. Oral antibiotics were administered, based on the diagnosis of acute dacryoadenitis at another clinic. The symptom had once subsided 20 days later but recurred. On the first examination, the right upper eyelid was swollen with tenderness. The right lacrimal gland was palpable. Blood tests revealed positive proteinase 3-anti-neutrophil cytoplasmic antibody. T2-weighted magnetic resonance and diffusion-weighted images showed a high signal intensity lesion in an enlarged right lacrimal gland, while apparent diffusion coefficient map demonstrated the lesion with a low signal intensity. We started administration of intravenous antibiotics. Abscess drainage and lacrimal gland biopsy were performed 4 days after the first examination. Culture test of the abscess showed only 1 colony growth of Cutibacterium acnes. The specimen harvested from the lacrimal gland showed proliferation of fibrous connective tissue and infiltration of inflammatory cells without vasculitis. After the drainage, the swelling gradually subsided. Administration of antibiotics discontinued at 22 days of follow-up. At 4-month follow-up, the patient did not have any symptom related to the lacrimal gland abscess. Conclusion: The diffusion-weighted images and apparent diffusion coefficient map are helpful for the diagnosis of lacrimal gland abscess when the culture tests provide poor results.
