Basi-parallel anatomical scanning-magnetic resonance imaging for the diagnosis of reversible cerebral vasoconstriction syndrome of the basilar artery: a case report.

Case: Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized and important cause of thunderclap headache. Delays in diagnosis may cause deterioration of symptoms and concomitant unnecessary investigations. However, the diagnosis of RCVS in the acute stage remains difficult.

Controlled normothermia for a cerebral air embolism complicating computed tomography-guided transthoracic needle biopsy of the lung.

Case: A 74-year-old woman underwent computed tomography-guided transthoracic needle biopsy of a small lung mass. Immediately after the procedure, she lost consciousness. After resuscitation, her brain computed tomography scan confirmed a cerebral air embolism.

Management of inadvertent vertebral artery injury due to central venous catheterization in a coagulopathic patient.

Case: A 72-year-old man was admitted to the intensive care unit for severe pancreatitis with coagulopathy. He underwent hemodialysis catheter insertion into the internal jugular vein that subsequently leaked arterial blood; vertebral artery cannulation was suspected following a computed tomography scan.

Outcome: Under angiographic guidance, the catheter was removed, and an arteriovenous fistula was identified.
