We reviewed the sonographic and MRI findings of tracheolaryngeal obstruction in the fetus. Conditions that can cause tracheolaryngeal obstruction include extrinsic causes such as lymphatic malformation, cervical teratoma and vascular rings and intrinsic causes such as congenital high airway obstruction syndrome (CHAOS). Accurate distinction of these(More)
BACKGROUND (131)I-metaiodobenzylguanidine (MIBG) is an active radiopharmaceutical in neuroblastoma. A previous study demonstrated that MIBG could be combined with vincristine and prolonged irinotecan, although 25% of first courses had grade 3 diarrhoea. The current phase I/II study evaluated MIBG with vincristine and 5 days of higher-dose irinotecan. (More)
Liposarcoma is a soft-tissue sarcoma typically seen in adults. It is extremely rare in children. It most often occurs in the extremities or in the retroperitoneum. We present a very rare case of an anterior mediastinal liposarcoma of the pleomorphic subtype in a 17-year-old girl, along with radiological and pathological correlation. The location, patient(More)
BACKGROUND Magnetic resonance imaging (MRI) is often used to diagnose and monitor treatment effects of juvenile spondyloarthropathy (SpA). Our objective was to describe MRI findings in juvenile SpA and determine predictors of active sacroiliitis and response to treatment. METHODS Children who had MRI of the sacroiliac (SI) joints and were referred to the(More)
The müllerian ducts are paired embryologic structures that undergo fusion and resorption in utero to give rise to the uterus, fallopian tubes, cervix, and upper two-thirds of the vagina. Interruption of normal development of the müllerian ducts can result in formation of müllerian duct anomalies (MDAs). MDAs are a broad and complex spectrum of abnormalities(More)
Extraneural metastatic disease resulting from a primary central nervous system neoplasm is a rare clinical finding in the pediatric population. We report a case of peritoneal glioblastoma carcinomatosis following placement of a ventriculoperitoneal shunt and chemoradiotherapy in a 6-year-old female patient who initially presented with diffuse intrinsic(More)
Hepatocyte-specific magnetic resonance imaging (MRI) contrast agents are commonly used to depict anatomic hepatobiliary lesions and are also useful in characterizing the kinetics of hepatocyte uptake and excretion. We report a case of a 13-year old female with progressive familial intrahepatic cholestasis (PFIC) type 1 who demonstrated decreased uptake and(More)
We report a case of primary malignant mixed tumor (MMT) of bone in an 18-year-old boy with X-ray, CT, MR, scintigraphic, FDG PET, and pathologic correlation. Primary MMT of bone is a highly aggressive tumor and presents both a diagnostic and clinical treatment challenge. This tumor is extremely rare and to the best of our knowledge, this is the first report(More)
