Abstract:
The lacrimal fossa can be invovled by a wide specturm of orbital pathology. The correct diagnosis is importantto avoid unnecessary procedure and to do appropriate management. 14 patients with mass lesions in the lacrimalfossa were evaluated with CT and clinical findings. The results were as follows: 1. Final diagnosis of 14 caseswith lacrimal fossa tumors was pleomorphic adenoma in 3 cases, adenoid cystic carcinoma in 1 case, pseudotumor incases, lymphoma in 2 cases, neurofibroma in 1 case, chloroma in 1 case and metastatic adenocarcinoma in 1 case. 2.The duration of symptoms of pleumorphic adenoma was more than 1 year and characteristic CT findings were globularmasses with pressure erosion of the adjacent bone. Patient wih adenoid cystic carcinoma had a short history ofsymptoms. CT showed a fusiform mass but intracranial extension with frank destruction of sphenoid bone. 3.Patients wtih pseudotumor and lymphoma had symptoms for less than 1 year. The CT findings were ill-definedinfiltrative patterns with scleral thickening and the differential diagnosis of them was difficult. 4. The marginsof neurofibroma and chloroma were well defined while that of the metastatic adenocarcinoma was ill-defined. 5. Thedegree and the extent of the contrast enhancement gave no benefit in the differential diagnosis of each diseaseentities and even of the benign and malignant lesions.
