DOI: 10.12809/hkjr1515315

Extravasation of contrast medium is a complication of contrast-enhanced computed tomography studies. Clinical presentations include minimal swelling, erythema and, when the extravasated volume is large, ulceration, compartment syndrome, and skin necrosis. Here we present an 80-year-old woman with


Magnetic Resonance Imaging of Fistula-in-ano

Full Article

CYH Chan, KYK Wong, SKY Kwok, WK Wong, KW Tang

Hong Kong J Radiol 2015;18:243-52

DOI: 10.12809/hkjr1515300

Fistula-in-ano is a highly devastating disease due to its high morbidity. In order to achieve excellent surgical outcome, preoperative evaluations are essential. Magnetic resonance imaging (MRI) allows high spatial resolution images and is highly accurate in delineating the type and extent of a perianal fistula.
