Huge pseudoaneurysms are rare and can potentially be life-threatening bleeding due to rupture. We report a patient presenting a huge pseudoaneurysm who underwent distal pancreatectomy with Warshaw's technique.

We describe a case of pancreatic tumor associated with a giant type IV hiatal hernia that had prolapsed into the posterior mediastinum. We initially performed hiatal hernia repair, followed by laparoscopic distal pancreatectomy, because the hernia repair enables performing pancreatectomy safety and in the normal anatomical position.

Infection of urachal remnant may cause recurrent abscesses. In the current case report, we describe an urachal remnant infection leading to a retroperitoneal abscess, which is extremely rare condition. In such cases, the recommended treatment is urachal remnant resection.
