Percutaneous Y-shape reconstructive biliary stenting in Klatskin cholangiocarcinoma through a single left-sided entry.

Percutaneous Y-shape reconstructive biliary stenting in the Klatskin tumor is typically performed through bilateral biliary access. Single access from a right-side biliary entry is the more commonly used side for biliary access in general. We present a successful Y-shaped biliary stent reconstruction through a single left-side biliary approach.

Brain magnetic resonance imaging and proton MR spectroscopic findings after metabolic crisis in 3-methylcrotonylglycinuria.

Magnetic resonance imaging (MRI) and magnetic resonance spectroscopic (MRS) findings in 3-methylcrotonylglycinuria presenting with acute metabolic decompensation in a previously healthy 7-year old female are described. The patient was hospitalized with fever, irritability, gastrointestinal problems, drowsiness, signs of upper motor neuron deficit, and rapidly progressive respiratory distress requiring assisted ventilation. Laboratory workup showed severe metabolic acidosis, and the diagnosis of 3-methylcrotonylglycinuria was established by the mass spectrometry analysis of urine sample.

Endovascular embolization of a giant aneurysm in medial posterior choroidal artery with associated arteriovenous malformation.

A 16-year-old male adolescent who presented with vomiting and headache and in the emergency department had a loss of consciousness, was discovered to have a large mass compressing the brainstem. CT scan showed two adjacent mass lesions. Digital subtraction angiography (DSA) revealed a giant aneurysm in the posterior medial choroidal artery, subsequently embolized with Guglielmi detachable coils (GDCs).
