Echocardiography showed transient cardiomyopathy with akinesia of the basal and midportions of the left ventricle and hyperkinesia of the apex. No evidence of ischemic cardiomyopathy on myocardial SPECT or ergonovine stress echocardiography was observed. The patient s condition at discharge had improved, but she later was diagnosed as having pheochromocytoma. The findings of transient cardiomyopathy revealed inverted Takotsubo cardiomyopathy related to pheochromocytoma. The recognition of such a rare cardiac manifestation should be considered in the diagnosis of pheochromocytoma.

(D) On systole. ased on the transthoracic echocardiogram, left ventricular abnormal wall movement with akinesia in the basal and mid-ventricle and hyperkinesis in the apical area had improved on day 7. D 임상경과 : 내원시흉통은니트로글리세린으로호전되었으며, 심인성쇼크로생각하고, 수액요법과도파민정주를실시한후혈압은 100/60 mmhg 로촉지되어도파민을감량하였고, 심전도모니터에서 190회 / 분이상의상심실성빈맥이있었으나 adenosine 투여후호전되었다. 입원 4일째혈역학적상태가안정되어도파민을중단하였으며, 분당 80회의정상동율동과함께내원시보였던 ST 분절하강소견은보이지않아 ( 그림 1) 도부타민심근관류검사를실시하였으나심근허혈은보이지않았다 ( 그림 3). 입원 7일째시행한추적심초음파에서좌심실의확장기말직경이 51 mm, 수축기말직경이 35 mm, 좌심실구혈률이 60% 로증가하였고, 심근벽의운동은정상이었다 ( 그림 2C, 2D). 입원 10일째실시한에르고노빈부하심초음파검사에서이상소견이보이지않아관상동맥조영술을실시할예정이었으나, 경제적인이유로더이상의검사를거부하고자의로 퇴원하였다. 퇴원후환자는 3년동안순환기내과외래에서경과관찰중두통과홍조가지속되어시행한복부전산화단층촬영에서 3 cm 크기의좌측부신종괴가발견되었다 ( 그림 3). 6개월간추적관찰중어지럼증으로인근지역병원에입원하여시행한복부전산화단층촬영에서좌측부신의종괴는 3.5 cm로크기가증가되었고, 간헐적으로혈압이 160/90 mmhg 으로상승하여본원으로전원되었다. 재입원 2일째부신자기공명영상촬영에서좌측부신에직경약 3 2.5 cm 크기의종괴가있고내부에 T1 강조영상에서저신호강도, T2 강조영상에서고신호강도를보여갈색세포종을의심할수있었다. 입원 4일째부신종괴의기능평가를위해시행한 24시간요검사에서노르에피네프린 157.5 μg/day ( 정상범위 : 15~80 μg/day), 에피네프린 329.5 μg/day ( 정상범위 : 20 μg/day 이하 ), 바닐만델산 6.48 mg/day ( 정상범위 : 8 mg/day 이하 ), 메타네 - S 118 -

Inverted Takotsubo cardiomyopathy는비교적최근에기술된증후군 17,19) 이나갈색세포종에서카테콜라민유도심근병증의한양상으로발현될수있다. 따라서본증례와같이내원시심전도에서하벽또는측벽유도혹은하벽과측벽유도모두에서 ST 분절의하강이있고심근효소의상승과함께심초음파검사에서 inverted Takotsubo cardiomyopathy를보이는환자에서는반드시갈색세포종의감별을고려하여야 할것으로생각된다. 요 61세여자환자가급성흉통을주소로내원하여시행한심전도와심초음파에서급성심근경색증후군이의심되었다. 심초음파검사에서좌심실기저부의운동저하와심첨부의과운동성이보였다. 심근관류검사와에르고노빈부하심초음파검사에서심근허혈의증거는없었다. 환자는호전된상태로퇴원하였고, 이후갈색세포종을진단받았다. 이전의가역적인심근병증은갈색세포종과연관된 inverted Takostubo cardiomyopathy로진단되었다. Inverted Takostubo cardiomyopathy는갈색세포종의매우드문심장합병증이므로이질환을진단할때꼭갈색세포종을고려하여야할것으로생각된다. 중심단어 : Inverted Takostubo Cardiomyopathy; 갈색세포종 약 REFERENCES 1) Sardesai SH, Mourant J, Sivathandon Y, Farrow R, Gibbons DO.
