Representative case. A 40-year-old woman (Case no. 7) presented with acute dyspnea after dilation and curettage due to missed abortion. Her blood pressure was 80/50 mmHg and heart rate was 120 bpm. (A) Two-dimensional echocardiography on admission day showed basal dyskinesis with severely depressed left ventricular ejection fraction (LVEF) of 15% and global longitudinal strain (GLS) of −1.9%. (B) Two months after treatment with mechanical ventilation, extracorporeal membrane oxygenation and continuous renal replacement therapy, her LVEF was improved to 61% and GLS to −21.0%. Her urinary excretions of metanephrine and epinephrine were increased to 2.0 mg/day and 50.9 µg/day, respectively. Abdominal magnetic resonance imaging study showed a 2.8 × 2.4 cm-sized mass (arrows) at right suprarenal area with (C) low on T1-weighted and (D) high signal intensity on T2-weighted images. (E) ¹²³I-metaiodobenzylguanidine (MIBG) single-photon emission computed tomography demonstrated intense MIBG uptake in the right adrenal mass (arrow) which was compatible with pheochromocytoma.
