Figure 2: Magnetic resonance imaging abdomen and computed tomogram-guided drainage in mediastinal pancreatic pseudocyst. (a) T2-weighted image shows hyperintense fluid collection (white arrow) posterior to the esophagus (black arrow). (b) T1-weighted image shows the hyperintense signal suggesting hemorrhagic fluid (white arrow). (c) Computed tomogram-guided drainage with pigtail catheter (arrow). (d) Follow-up magnetic resonance imaging after 1 week shows a significant reduction in the size of collection. Pigtail catheter seen in situ (arrow)
