Congenital lung malformations are often discovered incidentally on routine prenatal sonography or postnatal imaging. Lesions such as congenital cystic adenomatoid malformations (CCAM), sequestrations, bronchogenic cysts and congenital lobar emphysema may be asymptomatic at birth or at the time of discovery later in life. Some authors advocate simple(More)
UNLABELLED Congenital cystic adenomatoid malformation of the lung (CCAM) is diagnosed by prenatal ultrasonography with an increasing frequency but controversy persists as to its prognosis and prenatal management. METHOD A multi-institutional study of cases of CCAM diagnosed antenatally identified by ultrasonographers and by a review of hospital charts. (More)
BACKGROUND Third and fourth branchial remnants may result in cysts and abscesses that are in close contact with the thyroid gland. These anomalies are rare and often present diagnostic and therapeutic challenges. METHODS The charts of patients diagnosed with a branchial anomaly between July 1991 and July 2001 at the Montreal Children's Hospital were(More)
OBJECTIVE Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare müllerian anomaly consisting of uterine didelphy, hemivaginal septum, and ipsilateral renal agenesis. The purpose of this study was to evaluate the natural history and outcome of patients with HWWS. METHODS With ethics review board approval, all patients with uterine/vaginal anomalies were(More)
PEComa of the gastrointestinal tract, composed of perivascular epithelioid cells with myomelanocytic differentiation, is rare with previous literature limited to 16 case reports. There is a marked female preponderance and approximately one-third of the cases occur in the pediatric age group. We report PEComa with lymph node involvement occurring in the(More)
Congenital Pulmonary Airway Malformation (CPAM) and lung sequestration are often discovered on routine prenatal sonography. While some lesions may be large and cause serious complications in the fetus or newborn, many will be asymptomatic at birth. Some authors advocate simple observation because of the lack of data on the incidence of long-term(More)
BACKGROUND/PURPOSE In 1990, the authors reported excellent outcomes using a standard protocol to treat pediatric appendicitis. This protocol has been simplified further and a large retrospective review was conducted to assess current outcomes. METHODS All patients treated for presumed appendicitis between April 1997 and December 1999 were reviewed. All(More)
BACKGROUND Isolated torsion of the Fallopian tube, without ovarian torsion, is a rare cause of lower abdominal pain. We report our experience with 4 recent cases, along with data from a 20-year review of the pediatric literature. SUBJECTS AND METHODS The records of 4 cases encountered during a 3-year period were reviewed. A literature review was completed(More)
Confusion, controversy, and uncertainty are all terms applicable to the diagnosis and management of congenital lung lesions both prenatally and postnatally. This review examines the current status of fetal diagnosis and treatment of these lesions; reviews the various classifications, including congenital cystic adenomatoid malformation/congenital pulmonary(More)
BACKGROUND The aim of this study was to evaluate the outcome of laparoscopic (LA) vs open appendectomy (OA) in patients with perforated appendicitis in our center. METHODS Retrospective review from July 2002 to April 2007 (institutional review board-approved), evaluating 281 patients with perforated appendicitis based on surgical approach. We compared(More)
