CONTEXT
The lithopedion (calcified abdominal pregnancy) is a rare phenomenon and there are less than 300 cases reported in the medical literature.
CASE REPORT
In this case, a 40 year-old patient had had her only pregnancy 18 years earlier, without medical assistance since then. She came to our hospital with pain and tumoral mass of approximately 20 centimeters in diameter. Complementary examinations (abdominal X-ray, ultrasonography and computerized tomography) demonstrated an extra-uterine abdominal 31-week pregnancy with calcification areas. Exploratory laparotomy was performed, with extirpation of a well-conserved fetus with partially calcified ovular membranes.
背景
石胎（钙化性腹腔妊娠）是一种罕见现象，医学文献报道的病例不足300例。
病例报告
在本病例中，一名40岁患者18年前曾有过唯一一次妊娠，此后未接受过医疗救助。她因疼痛和直径约20厘米的肿瘤性肿块前来我院就诊。辅助检查（腹部X线、超声和计算机断层扫描）显示为宫外31周妊娠伴钙化区域。进行了剖腹探查术，摘除了一个保存完好的胎儿及部分钙化的胎膜。
