Cystic pancreatic neoplasms are a heterogeneous group of pathology, and intraductal papillary mucinous neoplasia is becoming more common. The aim of this study is to review our series of cystic pancreatic neoplasms that underwent surgery and to evaluate the similarities with Fukuoka recommendations.Retrospective review of our experience analyzing clinical and radiological data, indication for surgery and pathology study of 11 patients operated on in our centre from july 2011 to july 2015, aiming to evaluate the degree of agreement with the current consensus.In our series the majority of cases (7/11) had symptoms at diagnosis. Preoperative diagnosis was achieved in 10 patients using radiology and/or endoscopy. Indications for surgery were the presence of symptoms, radiological data suspicious of malignancy, and secondary branch neoplasia over 30mm. Pathological findings were malignancy in 6/11 cases (2 invasive neoplasia, 4 high grade dysplasia), moderate dysplasia in 2/11, low-grade dysplasia in 2/11 and no dysplasia in one patient.Surgical indication of intraductal mucinous pancreatic neoplasms depends on the associated symptoms, size, location, risk and suspicion of malignancy.

Spontaneous pneumoperitoneum is a common finding in patients with abdominal disorders. In 90% of cases, this entity results from hollow viscera perforation. Rupture of a pyogenic liver abscess is an infrequent complication occurring in 5 to 15% of cases. Pneumoperitoneum secondary to intraperitoneal rupture of an abscess is extremely rare and very few cases have been reported in the literature. Given its clinical interest, we report a case of pneumoperitoneum due to spontaneous rupture of a gas-containing pyogenic liver abscess.

Solitary and early brain metastases from colon carcinoma are unusual. This possibility must be kept in mind, in patients with cerebral metastasis of unknown adenocarcinoma. These patients could benefit from colonoscopy and CEA studies with the aim of achieving more early diagnosis and surgical resection. The case of a 48-year-old woman with brain metastasis diagnosed 4 months before the primary tumor, a colon cancer, is reported.
