Estudios mamográficos en un centro metropolitano de referencia en imágenes mamarias: Chile 2008-2018 ¿Vamos por el camino correcto? / Analysis of mammograms performed in a public imaging center in Santiago, Metropolitan Region Chile 2008-2018

BACKGROUND: Mammograms are one of the most effective preventive means for the early detection of breast cancer. OBJECTIVE: To describe the features of patients and results of mammograms performed at a public breast imaging service of the Santiago Metropolitan Area. MATERIAL AND METHODS: We reviewed the reports of mammograms performed on 174,017 women and 18 men, between 2008 and 2018 in an Imaging Center. The BI-RADS classification was used in the reports. RESULTS: Forty-six percent of mammograms (75,781) were reported as BI-RADS 2. The high proportion of BI-RADS 4 reports (674 reports) was seen in patients aged 40 to 49 years, corresponding to 30% of reports in this age range. Among patients aged 50 to 59 years, there were 779 BI-RADS 4 reports (35%). BI-RADS 5 reports were more common among patients aged 50 to 59 years (50 reports, 30%) and among patients aged 70 years or older (83 reports, 28%). CONCLUSIONS: The presence of a significant number of women between 40 and 49 years of age with a BI-RADS 4 mammography result stands out; being an opportunity to develop new clinical research and public health strategies within the framework of the Universal Health Care policy for breast cancer in Chile.

Resección hepática en enfermedad de Caroli localizada / Hepatic resection in localized Caroli's disease

Caroli disease is a cystic congenital malformation of the intrahepatic biliary tract, frequently associated with lithiasis. Commonly, cystic dilatations are bilateral and infrequently they affect only one hepatic lobule or segment. We report six patients with localized Caroli disease, three in the right and three in the left hepatic lobule, that were subjected to a hepatic resection. There were no postoperative complications or mortality. After 28 months of follow up, patients are asymptomatic and with normal hepatic function and ultrasonography. The importance of diagnosing localized Caroli disease, in which hepatic resection can be curative, is emphasized

Pólipo fibroide inflamatorio: causa de invaginación intestinal / Inflammatory fibroid polyp: cause of bowel intussusception

Se presentan dos casos de invaginación intestinal cuya causa fue un pólipo fibroide inflamatorio. Ellos corresponden a un niño y un paciente adulto. En ambos pacientes la invaginación fue precedida por una historia de dolor abdominal recurrente. Los estudios de imagen previo a la intervención quirúrgica fueron ultrasonografía abdominal y tomografía axial computarizada (TAC) en ambos casos. Se destacan las características del tumor y su presentación en el estudio de imágenes

Tumor papilar quístico del páncreas: un carcinoma infrecuente de buen pronóstico / Papillary cystic tumor of the pancreas: an unfrequent carcinoma of well prognosis

Papillary cystic tumor of the pancreas is a rare low grade carcinoma, with only 130 cases report in the English literature. We report a 22 years old female presenting with a palpable mass and abdominal pain. Abdominal ultrasound and CAT scan showed a solid-cystic lesion in the head of the pancreas. The patient was subjected to a partial pancreatoduodenectomy and the histological study of the surgical specimen disclosed a papillary cystic carcinoma. Post up course was uneventful and the patient is well at 8 months follow up
