Hypersensitivity Reactions to Transarterial Chemoembolization with Cisplatin and Ethiodized Oil: A Retrospective Cohort Study.

Purpose: To assess the incidence of hypersensitivity reactions (HSRs) and risk factors in patients with unresectable hepatocellular carcinoma (HCC) who have undergone transarterial chemoemblization (TACE) with cisplatin-ethiodized oil emulsion.

Materials And Methods: Between September 2014 and December 2019, patients with HCC in the authors' institution undergoing TACE with cisplatin-ethiodized oil emulsion were retrospectively reviewed. Clinical, laboratory, and imaging data (including age, sex, etiology of HCC, serum bilirubin, albumin, alpha-fetoprotein, prothrombin time, dose of cisplatin, and details of TACE procedure) and data on procedural complications were retrieved from the registry of TACE.

Chordoma at the skull base, spine, and sacrum: A pictorial essay.

Chordomas are rare tumors believed to be arising from the notochord remnant in the axial skeleton. Diagnosis is often difficult since they show overlapping imaging features with other more common disease including metastases. Since individualized papers are only discussing the imaging features at different locations, the aim of this pictorial review is to have a comprehensive review on the common imaging findings of chordomas along the entire neuroaxis with a series of pathological proven cases in a local tertiary hospital in Hong Kong.
