Duodenal pancreatic heterotopy diagnosed by magnetic resonance cholangiopancreatography: report of a case.

We describe herein the case of a heterotopic pancreas that caused stenosis in the second portion of the duodenum. A 46-year-old man presented with upper abdominal pain and a 12-month history of intermittent vomiting. There was no history of melena, hematochezia, hematemesis, clay-colored stools, jaundice, or hepatitis and he did not describe any food dyscrasias, although fatty foods and alcohol seemed to make the symptoms worse. No specific medication or change in position relieved the pain. An initial diagnosis of chronic pancreatitis with multiple pseudocysts was made on the basis of elevated serum amylase and lipase levels, and abdominal ultrasonography and computed tomography (CT) findings. Medical treatment with octreotide was given for 8 weeks, but without any marked effect. Double-contrast barium examination and esophagogastroduodenoscopy were not diagnostic. Magnetic resonance (MR) cholangiopancreatography revealed findings indicative of cystic dystrophy of a heterotopic pancreas (CDHP), and an endoscopy supported this diagnosis. A pancreatoduodenectomy was performed and pathological examination confirmed a diagnosis of CDHP. In our opinion, MR cholangiopancreatography is the diagnostic tool of choice when CDHP is suspected.

[Annular pancreas in adults: diagnostic considerations on a case]. / Il pancreas anulare nell'adulto: considerazioni diagnostiche su di un caso.

Annular Pancreas (AP) is a rare congenital anomaly that usually presents in childhood with symptoms referable to duodenal obstruction; nonetheless, this condition can manifest in adulthood with abdominal pain, pancreatitis, duodenal ulcer, pancreatic head mass. The Authors hereby discuss a case of AP observed in a 63 year-old patient in which EUS played a decisive role in achieving a certain diagnosis.

[Non-parasitic splenic cysts]. / Le cisti non parassitarie della milza.

Nonparasitic cysts of the spleen are uncommon and often result from blunt abdominal trauma. Nonsurgical management of blunt splenic injuries increases the number of observations of the post-traumatic cysts. Complications (infection, rupture and hemorrhage) are lifethreatening, difficult to diagnose and require urgent surgical management. Until recently, splenectomy has been the primary choice of treatment of these cysts. Small (< 4 cm) asymptomatic post-traumatic pseudocysts stand a reasonable chance of involution with time (3-36 months) and so may be initially observed. Splenic preservation by partial splenectomy, enucleation or by marsupialization is actually recommended in children when technically feasible. Splenectomy is required for voluminous, central, multifocal cysts, in the presence of complications and in the adults with low immunologic risk. The Authors report 5 cases of large cysts successfully treated by splenectomy with one 12-year-old girl treated in emergency for infection by Salmonella.
