| Abstract |
PURPOSE
To evaluate the clinical characteristics and results of outcomes in different types of orbital pseudotumor. METHODS: This study included 62 patients diagnosed with orbital pseudotumor between 2002 and 2007, who were followed-up for more than 6 months. The pseudotumor was classified into anterior, diffuse, apical, myositic, or lacrimal types according to computed tomography (CT) findings. All patients were initially treated with corticosteroids and checked for symptom improvement and response to the corticosteroids. RESULTS: Lacrimal type pseudotumor (61%, 39/62) showed the highest incidence, and lid swelling (97%, 60/62) was the most common symptom. Response rate to corticosteroid treatment was 84%, and the recurrence rate was 29%. CONCLUSIONS: The orbital pseudotumors were localized by computed tomography and classified to compare the symptoms, treatment efficacy and recurrence rates between the different types. The orbital pseudotumor is most commonly diagnosed based on clinical symptomsand radiologic features without biopsy. The orbital pseudotumor showed a good treatment response but also a high recurrence rate. Therefore, when starting treatment, it is important to consider differential diagnosis. It is recommended to carefully examine patients who have lid swelling for a few weeks with computed tomography before using corticosteroid treatment. |
