Peritoneal lymphomatosis is relatively uncommon cause of diffuse malignant peritoneal disease, and differentiating it from other causes of diffuse peritoneal disease such as peritoneal carcinomatosis is often difficult on imaging. Common findings observed in peritoneal lymphomatosis in contrast to other etiologies include frequent nodal involvement and splenomegaly. We present a case of diffuse peritoneal disease along with ovarian lesions in the absence of abdominal lymphadenopathy or splenomegaly on fluorodeoxyglucose positron emission tomography-computed tomography in the setting of elevated cancer antigen-125 levels, mimicking primary ovarian malignancy causing peritoneal carcinomatosis, which was finally proven to be lymphoma.
腹膜淋巴瘤是弥漫性恶性腹膜疾病相对少见的病因，在影像学上常常难以将其与弥漫性腹膜疾病的其他病因（如腹膜癌病）区分开来。与其他病因相比，腹膜淋巴瘤的常见表现包括频繁的淋巴结受累和脾肿大。我们报告一例弥漫性腹膜疾病合并卵巢病变的病例，在氟脱氧葡萄糖正电子发射断层扫描 - 计算机断层扫描检查中未发现腹部淋巴结肿大或脾肿大，癌抗原125水平升高，酷似原发性卵巢恶性肿瘤导致腹膜癌病，最终经证实为淋巴瘤。
