[Adult intestinal malrotation associated with intestinal volvulus]. / Malrotación intestinal en adulto asociada a vólvulo intestinal.

BACKGROUND: Intestinal malrotation is a congenital anomaly of the intestinal rotation and fixation, and usually occurs in the neonatal age. OBJECTIVE: Description of a clinical case associated with acute occlusive symptoms. CLINICAL CASE: A case of intestinal malrotation is presented in a previously asymptomatic woman of 46 years old with an intestinal obstruction, with radiology and surgical findings showing an absence of intestinal rotation. CONCLUSIONS: Intestinal malrotation in adults is often asymptomatic, and is diagnosed as a casual finding during a radiological examination performed for other reasons. Infrequently, it can be diagnosed in adults, associated with an acute abdomen.

[Jaundice secondary to giant pancreatic serous cystoadenoma]. / Ictericia secundaria a cistoadenoma seroso pancreático gigante.

Serous cystadenoma is the second most frequent pancreatic cystic neoplasm and accounts for 1-2% of exocrine neoplasms of the pancreas. Recently, they have been identified more frequently, due to the improvement in imaging techniques. Differential diagnosis should be performed with mucinous cystoadenoma, due to the latter´s potential for malignant transformation. We present the case of a female patient who underwent examination for painless jaundice and cholestasis, with a final diagnosis of pancreatic serous cystoadenoma.
