    Cistos primários do epitélio pigmentar da íris e corpo ciliar: aspectos de biomicroscopia ultra-sônica
    (Conselho Brasileiro de Oftalmologia, 2000-10-01) Ayres, Bernadete; Allemann, Norma [UNIFESP]; Nakanami, Celia [UNIFESP]; Adan, Consuelo B. D. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Purpose: To describe the ultrasound biomicroscopic characteristics, incidence, distribution and location of primary cysts of the iris and ciliary body pigment epithelium, and to differentiate them from solid lesions. Methods: A retrospective study was performed through a review of charts of 73 patients, 82 eyes, with echographic diagnosis of primary cysts of the iris and ciliary body pigment epithelium during a 36-month period (January/97 through December/99). All examinations were performed using an ultrasound biomicroscope applying standard immersion techniques. Results: Ultrasound biomicroscopy revealed typical findings of the primary cysts of the pigment epithelium such as thin and regular walls with no internal content. Incidence was higher in individuals included in the interval of 20 to 29 years of age (28.8%). Forty-eight patients (65.7%) were female. The cysts were found most frequently in the inferior and temporal sectors. Conclusions: Ultrasound biomicroscopy was a useful tool for evaluating cystic lesions of the iris and ciliary body, also valuable in differentiating these lesions from anterior segment tumors and evaluating potential complications. The knowledge of the echographic criteria and epidemiological characteristic can assist in the diagnosis of these lesions.

    Prevalence of simple liver cysts and hemangiomas in cirrhotic and non-cirrhotic patients submitted to magnetic resonance imaging
    (Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, 2013-07-01) Galvao, Breno Victor Tomaz; Torres, Lucas Rios; Cardia, Patricia Prando; Nunes, Thiago Franchi; Salvadori, Priscila Silveira; D'Ippolito, Giuseppe [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Objective To determine the prevalence of liver cysts and hemangiomas in the general population and in cirrhotic patients. Materials and Methods Retrospective, observational, and cross-sectional study selecting consecutive magnetic resonance imaging studies performed in the period from February to July 2011. A total of 303 patients (187 women and 116 men) with mean age of 53.3 years were included in the present study. Patients with previously known liver lesions were excluded. The images were consensually analyzed by two observers in the search for simple liver cysts and typical liver hemangiomas, according to universally accepted imaging criteria. Lesions prevalence, diameters and location were determined in both cirrhotic and non-cirrhotic individuals. Results The authors observed prevalence of 8.6% for hemangiomas and 14.5% for simple cysts. No statistically significant difference was observed in relation to prevalence of hemangiomas and cysts among cirrhotic and non-cirrhotic patients (p = 0.954; p = 0.472). Conclusion In the present study, the prevalence of cysts and hemangiomas was higher than the prevalence reported by autopsy series. No influence of cirrhosis was observed on the prevalence and appearance of such incidental lesions.
