Abstract:
Objective To investigate the CT findings of orbital inflammatory pseudotumor in different types and to improve the diagnosis and differential diagnosis of this disease.Methods CT findings of orbital inflammatory pseudotumor in 58 cases confirmed by clinic or pathology were analysed retrospectively.Results This disease could be categorized five types according to CT findings: ①mass type in 5 cases (8.6%), the characteristic CT findings were soft-tissue masses in intraorbit; ②diffusion type in 5 cases (8.6%) showed retrobulbar fat interspace of high-density without masses; ③myositis type in 22 cases(37.9%) showed the enlargement of entire muscles including the tendinous insertion;④lacrimal galnd type in 6 cases(10.3%) showed enlargement of lacrimal gland on CT; ⑤the mixed type in 20 cases (34.5%) showed hypertrophy of the extra-ocular muscles adjacent to mass and high-density of surrounding fat ,or hypertrophy of the extra-ocular muscles adjacent to enlarged lacrimal gland.There were in different degree of paranasal sinusitis such as maxillary sinusitis and/or ethmoid sinusitis in 22 cases(37.9%).Conclusion CT scan is of important role in diagnosing and differential diagnosing orbital inflammatory pseudotumor.
