腹腔鏡下に切除しえた仙骨前面パラガングリオーマの1例

Abstract

A 25-year-old woman, with chief complaints of palpitation and vomiting, was suspected of having acute myocarditis and was taken to our critical care center. She was diagnosed with Takotsubo syndrome based on the results of echocardiography, coronary angiography, and myocardial biopsy. The 24-hour urine test showed high levels of normetanephrine and noradrenaline. The abdominal computed tomographic scan showed a presacral tumor (26 mm) just below the aortic bifurcation, and ¹³¹I-meta-iodobenzylguanidine scintigraphy showed abnormal accumulation in the tumor. Finally, she was diagnosed with Takotsubo syndrome associated with presacral paraganglioma. The hemodynamics became stable with conservative treatment. Then she underwent elective laparoscopic surgery. The histopathological analysis revealed paraganglioma. The immunohistochemistry for succinate dehydrogenase was negative in the tumor cells. There has been no recurrence as of 15 months after surgery.
