Cardiac metastases of carcinoid tumours are extremely rare, and their diagnosis poses a significant challenge. A variety of techniques has been reported in the literature for this purpose, ranging from echocardiogram to the Indium-111 Octreotide, positron emission tomography using specific tracers, and biopsy. Occasionally, the diagnosis is only made post-mortem. Recently, CMR (cardiovascular magnetic resonance) has been added to the diagnostic toolkit. This case report describes the CMR sequences that can be used to characterize cardiac metastases of carcinoid tumours.
A 55-year-old woman with an antecedent history of resected carcinoid tumour of the ileocecal junction underwent whole-body In-111 Octreoscan single-photon emission computed tomography in the context of her follow-up. This raised the suspicion of pericardial involvement, which prompted a CMR study. Comprehensive CMR findings were consistent with isolated carcinoid tumour metastasis embedded within the anterior papillary muscle. We describe the CMR sequences that were used to characterize the metastasis.
The rarity of cardiac metastasis of carcinoid tumour makes its diagnosis challenging and warrants a high level of clinical suspicion. Cardiovascular magnetic resonance imaging proves to be an indispensable tool in the tissue characterization of such tumours.
类癌肿瘤的心脏转移极为罕见，其诊断面临重大挑战。文献中已报道了多种用于此目的的技术，从超声心动图到铟 - 111奥曲肽、使用特定示踪剂的正电子发射断层扫描以及活检。偶尔，诊断仅在尸检后才能做出。最近，心血管磁共振成像（CMR）已被纳入诊断工具。本病例报告描述了可用于表征类癌肿瘤心脏转移的CMR序列。
一名55岁女性，既往有回盲部类癌肿瘤切除病史，在随访期间接受了全身铟 - 111奥曲肽单光子发射计算机断层扫描。这引发了心包受累的怀疑，促使进行CMR研究。全面的CMR结果与嵌入前乳头肌内的孤立类癌肿瘤转移一致。我们描述了用于表征转移灶的CMR序列。
类癌肿瘤心脏转移的罕见性使其诊断具有挑战性，需要高度的临床怀疑。心血管磁共振成像被证明是此类肿瘤组织表征中不可或缺的工具。
