Peritoneal loose bodies are usually diagnosed incidentally. Only a few cases are documented in the literature. The pathophysiology of this condition is not fully known and its origin may possibly be related to the twisting and separation of epiploic appendages. The authors describe the case of a patient with a spherical solid lesion 6 cm in diameter, identified incidentally in the pelvic cavity of a 64 year old man. The patient underwent laparotomy and a free ovoid shaped white body was identified. Histological examination described a calcified and encapsulated mass with a steato-necrosis core. A review of all cases of giant peritoneal loose bodies described in the literature is included. Surgical excision is recommended when the giant peritoneal loose body diagnosis is uncertain or when they are symptomatic. Doctors should be aware of its existence in order to establish a proper diagnosis and treatment plan.
腹膜游离体通常是偶然诊断出来的。文献中仅有少数病例记载。这种病症的病理生理学尚未完全明确，其起源可能与网膜附件的扭转和分离有关。作者描述了一例64岁男性患者盆腔内偶然发现的直径6厘米的球形实性病变病例。患者接受了剖腹手术，发现一个游离的卵圆形白色物体。组织学检查显示为一个有钙化包膜且核心为脂肪坏死的肿块。文中还纳入了对文献中所描述的所有巨大腹膜游离体病例的综述。当巨大腹膜游离体诊断不明确或出现症状时，建议进行手术切除。医生应了解其存在，以便制定恰当的诊断和治疗方案。
