Incidental Detection of a Rare Pediatric High-Grade Fibrosarcoma in a Post-traumatic Setting: The Conundrum of Intra-Abdominal Hematoma versus Neoplasia

Figure 2

Axial T2-weighted image showing a left upper quadrant lesion with heterogenous hyperintense signal (arrow in (a)). Corresponding axial T2-weighted with fat saturation which shows no evidence of fat signal suppression within the lesion (arrow in (b)). Corresponding T1-weighted image with fat saturation showing no signal hyperintensity excluding the presence of methemoglobin (arrow in (c)). Dynamic contrast-enhanced sequences with subtraction technique (d–f) showed faint early arterial enhancement (arrow in (d)) which progressed in the venous phase (arrow in (e)) and continued to increase in signal intensity during equilibrium phase (arrow in (f)).
