On the non-contrast study, a few high-attenuating regions with attenuation number ranging from 60-70 HU were seen at the left external iliac region, left lumbar region (close to the anterolateral abdominal peritoneum) and left lower paracolic gutter, which are suggestive of acute clotted haemorrhage. These are likely to constitute "sentinel clot sign".
On arterial phase, vertical linear-like active contrast extravasation at the left lumbar region extends from the aforementioned acute clotted blood anteriorly to the left paracolic gutter posteriorly. Within the left lumbar anterolateral acute clotted haemorrhage, there is a spot of hyperdensity which has similar attenuation to the enhancement of artery, representing the "CT angiographic spot sign".
On portovenous and delay 5-minute phases, pooling of contrast noted at the left paracolic gutters.
Gross ascites. Multiple enhancing right pelvic and inguinal lymphadenopathy.
