OBJECTIVES To assess the impact on clinical management of introducing (18)F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)-computed tomography (CT) in to the work-up of patients with primary and recurrent biliary malignancy. METHODS Consecutive patients with primary biliary tumours undergoing FDG PET-CT at a single large tertiary… (More)
Cardiovascular malformations and cardiomyopathy are among the most common phenotypes caused by deletions of chromosome 1p36 which affect approximately 1 in 5000 newborns. Although these cardiac-related abnormalities are a significant source of morbidity and mortality associated with 1p36 deletions, most of the individual genes that contribute to these… (More)
In the current investigation, we prepared a series of novel spiro[indole-thiazolidines] derivatives (5a–5h) from 5-substituted isatin derivatives and thioglycolic acid (TGA) with ZrSiO2 as an efficient catalyst under microwave irradiation. The significant merits of this protocol have some significant merits such as simplicity in operation, simple, efficient… (More)
Fast radio bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances. Previous follow-up observations have failed to find additional bursts at the same dispersion measure (that is, the integrated column density of free electrons between source and telescope) and sky position as the… (More)
OBJECTIVE To report atypical MRI patterns associated with POLR3A and POLR3B mutations. METHODS This was a multicenter retrospective study to collect neuroradiologic, clinical, and molecular data of patients with mutations in POLR3A and POLR3B without the classic MRI phenotype, i.e., diffuse hypomyelination associated with relative T2 hypointensity of the… (More)
Extra-gonadal yolk sac tumors (YSTs) are rare and generally associated with poor outcomes. Involvement of the seminal vesicles is extremely rare with only one previously described case. We report a case of a primary YST of the seminal vesicles and discuss the management strategy.
Malignant rhabdoid tumors are aggressive malignancies that can rarely present as hepatic masses in the pediatric population. The imaging findings are often nonspecific and usually suggest other more common hepatic tumors. We report the radiologic appearance of malignant rhabdoid tumor in a 3-month-old female with pathologic correlation.
Vesicoureteral reflux (VUR) affects ∼1% of children. We present an unusual case of urinary retention secondary to an obstructing urethral stone, underlying reflux, and its management. A 7-year-old boy presenting with acute urinary retention had a palpable penile shaft swelling and patent urethral meatus on examination. Cysto-urethroscopy with a 6.6Fr… (More)
Introduction. To determine the value of a FDG-PET-CT scan in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) prior to chemoradiotherapy. Materials and Methods. Consecutive patients with stage III or IV HNSCC who had undergone a staging FDG-PET-CT scan prior to chemoradiotherapy between August 2008 and April 2011 were included.… (More)
