RESUMO
A 61-year-old male with a history of poorly differentiated squamous cell carcinoma of tongue who completed chemo-radiation was found to have bilateral lung nodules on follow-up positron emission tomography (PET) scan. He underwent computed tomography (CT)-guided lung biopsy. Sequential chest scans done during the procedure showed air-fluid level in the left ventricle, suggestive of air embolism. He was hemodynamically stable during the procedure, however at the end of the procedure he developed right-sided face and arm weakness with aphasia. Emergent CT scans including angiography of head and neck were done which did not show any bleed and was also negative for any air in intracranial vasculature. Patient was treated with 100% oxygen. His neurological symptoms resolved in 30 minutes and he was subsequently admitted to intensive care unit (ICU) for further management. Six hours later, repeat CT of chest was done which showed resolution of air embolism.
