INTRODUCTION: Serious postoperative complications including anastomotic leaks, pulmonary infections, and cardiac dysrhythmias occur in 20-40% of patients following esophagectomy for esophageal cancer. However, neurological complications such as pyogenic brain abscesses are rare. We report a case of a pyogenic brain abscess following esophagectomy for cancer.
CASE PRESENTATION: A 55-year-old male was admitted to an outside hospital with headaches and mental status changes two months after an Ivor-Lewis esophagectomy for cancer. Physical exam revealed a disoriented man with aphasia and left-sided weakness. Laboratory tests were unremarkable except for an elevated WBC count of 17.5. Brain MRI demonstrated a 2.5 x 2.5-cm ring-enhancing lesion in the right frontal lobe with cerebral edema. The patient was treated with IV steroids and anti-epileptics for presumed brain metastasis. He was then transferred to our hospital for further care. Within 12 hours, his clinical status worsened as he became non-verbal with flexor posturing and non-reactive pupils. Repeat MRI revealed a 3.3-cm right frontal lobe pyogenic abscess with surrounding edema (Figure 1). Vancomycin and Piperacillin/Tazobactam were initiated and craniotomy was performed with drainage of 15 mL of pus; culture of this fluid grew Streptococcus viridans. Postoperatively, he was transferred to our ICU and treated for septic shock. Further imaging revealed pulmonary infiltrates and hemoperitoneum. By ICU day 5, his mental status improved and he was transferred to the ward and subsequently discharged from the hospital. Blood cultures were negative throughout his hospital stay. Two months later, his cognitive and motor functions returned to baseline and imaging demonstrated resolution of the brain abscess.
DISCUSSION: Pyogenic brain abscesses are rare occurrences following esophagectomy. Streptococcus viridans colonizes the oropharynx and esophagus and has been reported to cause bacteremic sepsis after esophageal dilatation for benign strictures, but not following esophagectomy. We ascribe the development of pyogenic brain abscess in our patient to hematogenous seeding from a colonized oropharynx or entry of bacteria into the brain via the Batson’s paravertebral plexus. Surgical drainage of the pyogenic brain abscess and antimicrobial therapy are the mainstays of treatment.
CONCLUSIONS: Critical care practitioners need to be aware of pyogenic brain abscess as a rare and life-threatening complication of esophagectomy.
