ABSTRACT
PurposeTo evaluate multislice spiral CT (MSCT) imaging features of gastric heterotopic pancreas.Materials and Methods MSCT features in 15 patients with pathology confirmed gastric heterotopic pancreas were retrospectively reviewed, including location, shape and border, size, CT value of gastric heterotopic pancreas and the normal pancreas.Results Twelve lesions were located in the gastric antrum, 11 were in the greater curvature. Intraluminal growth was found in 11 cases. 10 lesions were ill-defined. The mean longitudinal diameter (LD)/short diameter (SD) of the lesion was 1.89. The measurement showed high agreement with 0.99 ICC of LD and 0.98 ICC of SD. All lesions showed homogeneous and continuous enhancement, of which 4 cases showed surface dimpling. The plain and the portal vein phase CT values of gastric heterotopic pancreas and the normal pancreas had no significant differences (t=0.402 and—1.050, P>0.05), while the arterial phase CT value between gastric heterotopic pancreas and the normal pancreas were significantly different (t=3.13,P<0.05).Conclusion Gastric heterotopic pancreas demonstrates typical imaging features on MSCT which are helpful in the diagnosis and differential diagnosis.
ABSTRACT
OBJETIVO: Este trabalho tem por objetivo fazer uma revisão da malformação congênita denominada de agenesia dorsal do pâncreas (ADP) e de outras malformações congênitas pancreáticas, com base em um caso clínico raro e exemplar da problemática das malformações pancreáticas. Pretende-se rever a informação mais recente publicada na literatura nacional e internacional acerca das malformações congênitas pancreáticas e investigar a diversidade de formas de apresentação clínica da ADP e de outras malformações congênitas do pâncreas. Pretende-se saber em que situações há indicação terapêutica, qual a altura mais adequada de intervir, quais as modalidades disponíveis para o tratamento médico e ou cirúrgico das malformações congênitas pancreáticas. RESULTADOS: A ADP é uma malformação muito rara que surge durante a organogênese. Nas últimas décadas, foi produzido um volume importante de informação genética e embriológica que ajuda a compreender as causas das malformações pancreáticas. As malformações pancreáticas têm de ser estudadas e compreendidas no seu conjunto. CONCLUSÃO: A malformação pancreática é uma causa de pancreatite aguda e crônica no adulto, pouco estudada. A possibilidade da existência de malformações pancreáticas deve estar sempre presente em doentes com pancreatite aguda ou crônica sem causa evidente.
OBJECTIVE: This study aimed to review the congenital malformation known as agenesis of the dorsal pancreas (ADP) and other pancreatic birth defects, based on a rare and exemplary clinical case of pancreatic malformations. The intent was to review the latest information published in the national and international literature on pancreatic birth defects, and to investigate the diversity of clinical presentations of ADP and other congenital pancreas abnormalities. The purpose was to identify which situations have therapeutic indication, the most appropriate time to institute treatment, and the currently available medical or surgical treatment of pancreatic congenital malformations. RESULTS: ADP is a very rare malformation that occurs during organogenesis. In the last decades, a large volume of embryological and genetic information has been obtained, helping to understand the causes of pancreatic malformations, which must be studied and understood as a whole. CONCLUSION: Pancreatic malformations are infrequently studied causes of acute and chronic pancreatiWtis in adults. The possibility of pancreatic malformations should always be considered in patients with acute or chronic pancreatitis with no evident cause.
