Lacrimal sac diverticulum is a rare condition, and its various symptoms complicate differential diagnosis. We present cases of a peculiar type of lacrimal diverticulum. A 5-year-old girl and a 50-year-old woman presented with a protruding mass inferior to the medial canthus. Each lacrimal system was patent to irrigation. The masses compressed and distorted the lacrimal passage and had no apparent connection with the lacrimal sac in dacryocystography or computed tomography. Surgical exploration and complete excision of the masses were completed. Each patient had an inverted Y- and an inverted V-shaped multilobular cystic mass that was pathologically confirmed as a lacrimal sac diverticulum. Lacrimal sac diverticula may rarely take the form of a multilobular cyst and can present as a lower lid mass. We speculate that an abnormality in lacrimal embryogenesis resulted in multiple blind pouches, a peculiar type of lacrimal sac diverticulum.

A right-sided aortic arch (RAA) is a rare congenital anomaly, and Stanford type B dissection aneurysms involving this anomaly is also uncommon. Surgical approaches to dealing with an RAA are complicated by the unusual anatomical features of the condition. Here we report the case of a 47-year-old male who had a type B dissecting aneurysm involving an RAA with Kommerell's diverticulum. Graft replacement was successfully performed with an uneventful postoperative course.

An intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly consisted of a sac-like mucosal projection within the second portion of the duodenum. Even though most of cases are asymptomatic, patients may develop recurrent abdominal pain, pancreatitis, and gastrointestinal bleeding. We report a case of symptomatic IDD which presented as acute pancreatitis and obscure gastrointestinal bleeding. Diagnosis was made by typical findings of upper GI series and coronal reformatted CT images. Although surgical resection is the treatment of choice, endoscopic incision and ligation with detachable snare was performed which led to a good result.
