Abstract/OtherAbstract:

A 63-year-old white female with a history of metastatic breast cancer to the liver developed acute-onset nausea, vomiting, mental status change, and generalized seizures following transarterial chemoembolization using doxorubicin. The patient was hospitalized with the above symptoms immediately following transarterial chemoembolization using drug eluting bead doxorubicin into the right hepatic artery. The patient developed intractable nausea, vomiting, and abdominal pain and had a generalized tonic-clonic seizure lasting for 40 seconds, approximately 24 hours after the procedure. The patient was confused and lethargic for 2 days with progressive improvement in her mental status. Her neurological examination showed encephalopathy with disorientation to time, place or person, and she also had a glassy look. Cranial nerves were normal other than lack of response to threat stimulus bilaterally; motor and sensory examination was unremarkable. Initial blood pressure was 130/90 mm Hg and routine chemistry and complete blood count on admission were within normal limits. The cerebrospinal fluid analysis showed clear and colorless fluid with glucose of 56 mg/dL, protein of 42 mg/dL, white blood cells of 2/μL, and red blood cells of 10/μL and did not show any evidence of infectious or toxic etiology on encephalopathy. Continuous electro encephalography showed diffuse slowing but no epileptiform discharges. The magnetic resonance imaging (MRI) revealed increased signal intensity in the bilateral parieto-occipital area, right more than the left, on fluid-attenuated inversion recovery, apparent diffusion coefficient, and T2-weighted imaging, with no increased signal on diffusion weighted image consistent with vasogenic edema. The patient's symptoms and MRI findings were consistent with diagnosis of posterior reversible encephalopathy syndrome. Resolution of the MRI changes is noted on the follow-up imaging 8 weeks later. Posterior reversible encephalopathy syndrome in this case is most likely related to intra-arterial doxorubicin infusion because of the temporal association between administration, symptom onset, and MRI changes. |
