Unintentional direct intraventricular injection of gadolinium with fatal outcome: report of a case

Description
Summary:Gadolinium diethylenetriamine penta-acetic acid (Gd-DTPA) is the main contrast agent used in MRI, known for its good tolerance and rare toxicity. Even intrathecal injection of limited doses of Gadolinium can be performed in some indications. To our knowledge, only 3cases of accidental intraventricular injection of Gadolinium have been yet reported in the literature. We report the case of a 40-year-old male patient, who presented with headaches and vomiting. Brain MRI showed a right parietal abscess. The patient underwent emergent surgery for drainage of the septic collection. Postoperative MRI showed the development of a hydrocephalus related to a ventriculitis. Another surgery was performed to set up an external ventricular shunt, which lead to an improvement of the neurological status. A control brain MRI was scheduled for the patient, which revealed extensive abnormal enhancement inside the right lateral ventricle, on the basal cisterns as well as a leptomeningeal enhancement. Shortly after Gadolinium injection, the patient presented a tonic-clonic seizure. This clinico-radiological context leads to discover of the inadvertent intraventricular administration. Afterward, the patient's condition quickly deteriorated. Two days after the MRI he presented a cardiorespiratory arrest followed by death. Direct administration of Gadolinium into a ventriculostomy mistaken for intravenous catheter is a rare but harmful situation. Despite their rarity, such cases prove the importance of tracing all lines to their insertion sites to be confident of their appropriateness for injection.
