Abstract

Metastasis of neuroendocrine tumor to the myocardium is rare. We present a case of 64-year-old woman, who presented initially with abdominal pain and large adnexal mass. The image-guided biopsy showed low-grade neuroendocrine tumor with Ki67 less than 2% within the ovarian tissue. CT staging revealed bilateral adnexal masses, liver metastases, and primary lesion in the terminal ileum. Octreoscan showed marked tracer uptake within the lower esophagus not related to obvious mass on CT scan; the echocardiography confirmed the presence of a 2.7 cm LV/LA mass. In this case, close correlation between ECHO and the octreoscan obviated need for myocardial biopsy.

摘要

神经内分泌肿瘤转移至心肌较为罕见。我们报告了一例 64 岁女性，最初表现为腹痛和附件包块。影像学引导下的活检显示卵巢组织中低级别神经内分泌肿瘤，Ki67 增殖指数小于 2%。CT 分期显示双侧附件包块、肝转移和末端回肠原发性病变。奥曲肽扫描显示食管下段有明显的示踪剂摄取，与 CT 扫描未见明显肿块相关；超声心动图证实存在 2.7cm 的左心室/左心房肿块。在本例中，ECHO 和奥曲肽扫描之间的密切相关性排除了心肌活检的需要。
