Abstract


This study aims to expand the general understanding of benign pelvic tumors and improve their diagnosis via an analysis of their epidemiological and radiological features. Data from 201 internal patients diagnosed with benign pelvic tumors and treated from July 1958 to October 2011 were analyzed. The age and sex of patients were recorded. The age of disease onset and male-to-female ratio were analyzed. Pathological data were reviewed to determine the type of tumors whereas radiological data were examined to determine the anatomic sites and radiological features of the tumors. Based on the aforementioned data, the epidemiological features of all benign pelvic tumors were analyzed via the statistical analysis of sex, age, tumor types, locations and radiological features. The study group consisted of 114 males and 87 females, with the male-to-female ratio being 1.31:1. The disease onset age was between 5 and 72 years old, with a median and mean age of 28 and 30 years old, respectively. Pathological results showed that there were 59 giant cell tumors (GCTs), 53 osteochondromas, 17 simple bone cysts (SBCs), 15 aneurysmal bone cysts (ABCs), 14 osteofibrous dysplasias and 13 chondroblastomas. The tumors frequently occurred around the acetabulum. GCTs of bone and ABCs were more invasive, often involving multiple partitions. This disease has a high incidence and prevalence in individuals <40 years old. A comprehensive knowledge of epidemiological and radiological features is beneficial in early diagnosis of benign pelvic tumors.
