(A) Post-procedure ECG shows significant ST elevations in leads V1-V6. (B) After 2 h of treatment, the ST segments have reduced. (C) One month later, ECG shows T wave inversion with ST depression in leads V1-V6.

The electrocardiogram (ECG) showed ST-segment elevation in leads V1-V6 (Figure 1A), suggesting an acute large anterior wall ST-segment elevation myocardial infarction. One hour later, the patient showed clinical relief of chest discomfort with progressive normalization of ECG (Figure 1B). The ECG showed T inversion in V1-V6 (Figure 1C).
(A) Sagittal T2WI reveals abnormally Linear hyperintensity in the thoracic cord, extending from T2 to 10 level. (B) Axial T2WI shows the high signal intensity in the anterior horn of the gray matter (owl's eye appearance) at the T8 level.

The MRI revealed a hyperintensity in the thoracic cord from T2 to 10 level on T2-weighted images (T2WI) (Figures 2A,B).
(A) After injection of agitated saline, microbubbles are visible in the left ventricle by transthoracic echocardiography. (B) After the Valsalva maneuver, a large volume of microbubbles is filling the left ventricular and subsequently the left ventricular.

Valsalva maneuver (Figure 3B), indicating the presence of a large patent foramen ovale (PFO). Vascular ultrasound didn't detect venous thrombosis in the four extremities.
One month later, sagittal (A) and axial T2WI (B) shows a decrease in the hyperintense region.

MRI showed a decrease in the size of spinal cord lesion (Figure 4).
Nine months later, sagittal (A) and axial T2WI (B) showed that the lesion volume has significantly reduced.

Follow-up MRI showed the lesion volume on T2WI has significantly reduced (Figure 5).
