Objetivos

Describir los hallazgos por TC helicoidal de una entidad poco conocida: la groove pancreatitis o pancreatitis del surco pancreaticoduodenal (SPD), y revisar el diagnóstico diferencial de dicha enti-dad.

Material y métodos

Presentamos ocho casos de pancreatitis del surco, todos estudiados con TC helicoidal. Se dispone de correlación anatomopatológica en dos casos a los que se les realizó duodenopan-createctomía cefálica y en los otros seis casos se dispone de un segui-miento radiológico que abarca de cinco a 36 meses.

Resultados

En todos los casos la TC helicoidal mostró ensancha-miento y aumento de la densidad de la grasa del SPD, con escasa cap-tación de contraste que refleja el componente fibroso de esta afección, asociada a áreas quísticas en su interior y/o en la pared duodenal. La cabeza pancreática estaba respetada en las formas «puras» de la pancreatitis del surco y se visualizaban zonas hipodensas en las formas «segmentarias cefálicas».

Conclusión

El conocimiento de esta forma poco frecuente de pancreatitis crónica y los hallazgos radiológicos que permiten su diagnóstico son importantes para el radiólogo, ya que su diagnóstico diferencial incluye las neoplasias de la región periampular.

Aim

To describe the spiral CT findings of groove pancreatitis, a little known entitiy, and to review its differential diagnosis.

Material and methods

We present 8 cases of groove pancreatitis, or pancreatitis affecting the «groove» between pancreatic head, duodenum and common bile duct, all studied with spiral CT. For two cases, in which were performed cephalic duodenopancreatectomies, anato-mopathological correlations were available. In the other 6 cases, radiological follow-ups of anywhere between 5 and 36 months were utilized.

Results

In all eight cases, spiral CT showed expansion and increasing density of lipids within the «groove», with poor contrast enhancement indicative of the fibrous nature of this pathology, and associated with cystic areas in its interior and/or the duodenal wall. The pancreatic head was unaffected in «pure» forms of groove pancreatitis, and hypodense areas were observed in zones of «cephalic segmental» enhancement.

Conclusion

Knowledge of this little known form of chronic pancreatitis, and the radiological findings that permit its diagnosis are important for the radiologist since its differential diagnosis includes neo-plasias of the peri-ampullary region.
