  • 간암의 정맥계 침범은 흔하나 심장 침범은 드물고 예후가 불량할 뿐 아니라 급사의 위험이 있다. 본 증례처럼 간세포암이 혈관계를 통해 우심방까지 전이된 경우 노작성 호흡곤란 같은 심부전에 의한 증상을 나타낼 수 있어서 간세포암의 간외 전이를 의심하기는 쉽지 않고, 원발 병소를 찾기 위해서 여러 가지 진단적 검사를 시행하여야 한다. F-18 FDG PET/CT는 기능적으로 암세포의 당대사 항진을 3차원적인 입체 영상으로 국소화하기 때문에 비침습적이며 경제적으로 간세포암의 침범 및 간외전이를 쉽게 확인할 수 있다. 저자들은 호흡곤란을 주소로 내원한 55세 남자 환자에서 PET/CT를 통해서 간세포암과 간세포암의 우심방 침범을 진단하는데 도움을 받았기에 이를 문헌고찰과 함께 보고하는 바이다.

  • We report a case of invasive pulmonary aspergillosis invading the mediastinum and the left atrium. A 70-year-old woman was hospitalized for dyspnea. She had been well controlled for her diabetes mellitus and hypertension. The chest X-ray disclosed mediastinal widening, and the computed tomography scan of the chest showed that there was a large mediastinal mass and this lesion extended into the left atrium and right bronchus. The cardiac echocardiography showed that a huge mediastinal cystic mass compressed in the right atrium and a hyperechoic polypoid lesion in the left. The pathology from the bronchoscopic biopsy observed abundant fungal hyphae which was stained with periodic acid-Schiff and Gomori's methenamine silver. Despite the treatment with antifungal agents, she died from cardiac tamponade after three months. Invasive pulmonary aspergillosis, which involves the mediastinum and the heart, is very rare in immunocompetent patients.

  • A 7-year-old, intact female Yorkshire terrier dog was presented for coughing, anorexia, chest pain and dyspnea. Right lateral thoracic radiograph demonstrated a large mass shape on the heart base with decreased cardiac silhouette and severe right deviation of the trachea with the heart shifted to the left thoracic wall was observed on the ventrodorsal thoracic projection. Echocardiographic examination revealed a large rounded mass compressing left atrium around the heart base without signs of pericardial effusion. On computed tomographic (CT) findings, sagittal CT images depicted the possibility of cranial vena caval invasion and heart base involvement of the mass associated with biatrial compression. Dorsal CT image revealed the right deviation of trachea due to the heart base mass and markedly shrunk lung space was detected on the transverse CT image. Because the dog suddenly had died during the recovery from anesthesia after finishing CT scan, necropsy was performed. On gross findings, a large and lobulated mass was located at the base of the heart. A poorly-demarcated, infiltrative, multilobulated tumor composed of polyhedral cells in solid cellular sheets was confirmed based on histopathologic examination. This dog was diagnosed as a chemodectoma. This case report describes the clinical findings, diagnostic consistency of thoracic radiography, echocardiography and CT, and histopathologic confirmation in a spontaneously occurring chemodectoma with a Yorkshire terrier dog.

  • Sorafenib is indicated for the treatment of advanced hepatocellular carcinoma (HCC), but although rare, tumor lysis syndrome (TLS) can be fatal in HCC patients with a large tumor burden. The authors describe the case of a 55-year-old hepatitis B carrier who visited our clinic with progressive dyspnea for 3 weeks. Chest and abdominal computed tomography revealed a huge HCC in the left lobe of the liver with invasion of the inferior vena cava, right atrium, and pulmonary arteries. After 8 days of sorafenib administration, TLS was diagnosed based on the characteristic findings of hyperuricemia, hyperkalemia, and acute kidney injury with massive tumor necrosis by follow-up imaging. Despite discontinuation of sorafenib and supportive care, the patient's clinical course rapidly deteriorated. The authors describe a rare but fatal complication that occurred soon after sorafenib initiation for HCC. Careful follow-up is required after commencing sorafenib therapy for the early diagnosis and management of TLS.

  • 하행대동맥의 급성박리에 대한 외과적 치료에 대해서는 논란이 많다. 하행대동맥의 급성 박리병변이 수술적응이 될 경우 대동맥 차단시간은 30분 이상 소요될 수 있으므로 척수손상을 예방하기 위해 대동맥 차단부위 하방에 혈류를 유지하기 위한 여러 방법이 소개되었다. 저자들은 파열(혈흉) 및 쇼크의 합병증을 동반한 하행 대동맥의 급성 박리증 8예를 체외순환법을 이용하여 수술하고 그 방법에 대한 안전성과 효용성을 찾고자 하였다. 체외순환방법에 있어서는 대동맥병변의 상하에 2개의 동맥카뉼라를 넣어 대동맥 차단으로 수술 도중 상하체의 혈류공급을 동시에 이루어지도록 하였고, 산화기로 정맥혈의 환류를 위해 우심방이나 좌대퇴정맥에 정맥관을 삽입하였다. 비교적 장시간의 대동맥 차단에도 불구하고 수술후 8예 모두에서 척수손상은 없었다. 2예(25%)의 병원사망(각각 술후 31일과 41일)은 비교적 고령에서 지연성 합병증인 폐농양, 호흡부전증 등에 의해 발생했다. 주위조직의 부종 및 연약함 때문에 수술시간이 연장될 수 있는 급성 하행동맥 박리증에서 체외 순환방법하의 인공혈관 대치술은 대동맥 차단시간의 연장에 의한 척수 허혈손상을 피할 수 있는 안전하고 효과적인 외과적 치료방법이 될 수 있을 것으로 사료된다.
