Purpose: The incidence and clinical and imaging criteria of different pathological forms of lacrimal fossa lesions in the Delta region of Egypt were studied.
Methods: A retrospective study of patients with lacrimal fossa lesions for the past 10 years was conducted. A total of 146 cases were identified. Their medical records were reviewed for clinical and imaging data (computed tomography scan, magnetic resonance imaging scan, or both). A definitive diagnosis based on pathological examination of biopsies was also reviewed.
Results: Among the patients reviewed, 43.15% had inflammatory lacrimal gland lesions, 26.71% had lymphoproliferative lesions, and 21.92% had epithelial lesions; 8.22% had rare lesions (5.48% were dacryops and 2.74% had hemangioma). The study included 71.92% benign lesions and 28.08% malignant lesions, which were distributed between 19.18% malignant lymphoma and 8.9% malignant epithelial tumors. According to the pathological origin of the lesions, they may be classified into 78.08% nonepithelial lesions and 21.92% epithelial lesions (16.44% epithelial tumors, and 5.48% dermoid cysts).
Conclusion: Lacrimal fossa lesions show a wide pathological range. Inflammatory lesions are most frequent, followed by lymphoproliferative and epithelial lesions. Analysis of clinical and radiological criteria is helpful in the differential diagnosis of lacrimal gland lesions.
