A 75-year-old
man was admitted to the hospital because of transient unconsciousness
and dysarthria. Brain CT and MRI demonstrated a recent cerebellar
infarction. Physical examination revealed a continuous extracardiac
murmur maximally auscultated (Levine III) between the inner edge of the
right scapula and the upper thoracic vertebrae. Color Doppler thoracic
ultrasonography recorded at this point disclosed abnormal blood flow
signals, ie, red (tubular configuration;
Figure 1A
), mosaic (circular;
Figure 1B), and blue (tubular;
Figure 1C) signals. Pulsed-Doppler ultrasonographic
recordings obtained from the midportion of each signal demonstrated
flows toward the transducer
(Figure 2A), bidirectional
(Figure 2B), and away from the transducer
(Figure 2C) on the right upper part of the patient’s
back. 3D contrast-enhanced MR angiography
(Figure 3) confirmed anomalous vessels, indicated by the
color Doppler ultrasonographic findings; ie, a feeding artery (arrows)
originating from the right pulmonary artery, arteriovenous fistula
(asterisk), and draining vein (arrowheads) coursing into the left
atrium. Multiple
telangiectasias1 were
observed on the gastric endoscopy as cherry-red hillocks
(Figure 4).
