A 76-year-old male diagnosed with Veillonella bacteremia presented with a sudden onset of back pain, fever, and chills of four days duration. Although the fever and chills had since subsided, the back pain continued to persist and was exacerbated with positional change. CT scans revealed a psoas abscess with extradural extension, along with indications of lumbar osteomyelitis. MRI scans were unable to be obtained owing to the patient’s pacemaker. Due to medication allergies and growing sensitivity to the infection, the patient was transferred to MICU for a short period to be desensitized to ampicillin-sulbactam. Interventional Radiology then placed a retroperitoneal drain for the psoas abscess as well as a PICC line for IV antibiotic administration at home.\nDuring the following week, the Neurosurgery service performed laminectomy at levels L4-S1. Bilateral medial facetectomies and foraminotomies were also performed at L4-L5 and L5-S1 to fully decompress the exiting nerve root and thecal sac. Significant facet arthropathy was noted. The extradural abscess, which was revealed to be a large synovial cyst with no pus, was resected. Cultures were taken and sent for laboratory analysis, revealing the presence of Veillonella species. Post-operatively, CT scans indicated a resolving abscess. The patient was discharged and instructed to complete his course of ampicillin-sulbactam at home and switch to metronidazole and levofloxacin for a total six-week course of antibiotics.\nThe patient re-presented to the hospital 18 days after the neurosurgical operation complaining of worsening back pain radiating into his posterior buttocks that began 10 days after the operation. CT scans revealed considerable interval decrease in the psoas abscess but extensive osseous destruction in the L5-S1 region, anterior to the laminectomy sites, thereby advancing concerns of osteomyelitis. CT scans revealed trace retrolisthesis of L2 on L3 and L3 on L4, as well as grade 1 anterolisthesis of L4 on L5. There was multilevel disc height loss, most severe at L3-L4 and L5-S1, and persistent narrowing of the thecal sac. Fluid was observed posterior to the surgical site along with phlegmonous changes extending from L4-S1. A small abscess was also seen in the S1 prevertebral soft tissues. Interval erosions of the L5 and S1 endplates were noted, compatible with discitis. All of these findings were consistent with progressive osteomyelitis. Furthermore, bone and tissue cultures revealed continued Veillonella infection, perhaps due to a combination of both insufficient debridement as well as inadequate duration of antibiotic treatment. The patient was instructed to begin IV vancomycin in addition to metronidazole and levofloxacin for an additional 6 weeks.\nThe patient presented to the office 25 days later with unbearable, radiating lower back pain forcing him to use a wheelchair to move about. CT scans indicated progressive destructive changes of the L5-S1 vertebral body endplates. Two presacral abscesses measuring 4 mm and 7 mm were identified anterior to S1; additional microabscesses were found in the prevertebral phlegmon at the L5 level. A larger abscess measuring 15 mm was identified dorsal to the thecal sac at the previous L5 laminectomy site, leading to a narrowing of the dural sac. Progressive destruction of the vertebral bodies was noted with fragmentation of the inferior endplate of L5 and superior endplate of S1. Reflexes were absent bilaterally in the lower limbs and there was decreased sensation to light touch. Tissue cultures taken from the affected vertebrae were all negative at this time, and given the patient’s debilitated status, reconstructive spine surgery was indicated.\nPreoperative X-ray revealed spondylolisthesis of L5 on S1, and a CT myelogram showed severe multilevel spinal stenosis from L2 to S1. Therefore, the patient underwent a L2-S1 lumbar laminectomy with posterior segmental instrumentation and posterolateral arthrodesis from the L2 to the ilium using pedicle screws and iliac bolts bilaterally. Decompression of spinal nerves was achieved by posterior lumbar laminectomy, bilateral medial facetectomies, and bilateral foraminotomies at all spinal levels between L2 and S1. Given the patient’s history of infection, an allograft was used to form a final instrumented fusion mass. (Figs. , , , and ).\nThe patient recovered well after surgery. Final blood and tissue cultures were all negative. CT scans indicated resolution of the remaining abscesses. He was discharged and instructed to complete the previously prescribed course of antibiotics and follow-up with rehabilitation facilities. After 12 months of rehabilitation therapy, the patient regained a majority of mobility and ambulated with cane. However, at the 12 month follow up visit, he complained of groin pain. Additional physical therapy including aqua therapy was ordered and followed. At the 18 month follow up visit, the patient is noted to be doing quite well with occasional back discomfort and continues to ambulate with a cane.
A 31-year-old male with a history of heavy alcohol use presented to our hospital with a 3-day history of lower extremity edema, abdominal swelling, and periumbilical pain. He reported use of 6 cans of beer daily, with the most recent use 3 days prior to admission. On presentation, the patient was alert and oriented only to person and self. His vital signs were a temperature of 38.5°C, heart rate 129 beats/minute, and blood pressure 132/74 mmHg. Physical exam was significant for scleral icterus, asterixis, systolic murmur, abdominal distention with caput medusae, palmar erythema, and spider angiomas on his chest.\nLaboratory tests revealed a white blood cell (WBC) count of 11.7 K/mm3 (with 78% neutrophils, absolute lymphocyte count 1.3 K/mm3, and absolute monocyte count 1.0 K/mm3), platelets 88 K/mm3, lactate 2.1 mmol/L, alkaline phosphatase (ALP) 503 U/L, aspartate aminotransferase (AST) 172 U/L, and alanine aminotransferase (ALT) 19 U/L. Maddrey's Discriminant Function score was 35.3 (Prothrombin time 19.2 seconds and total bilirubin 6.8 mg/dL). Ascitic fluid analysis after paracentesis was negative for spontaneous bacterial peritonitis, with a nucleated cell count of 79/cumm and 23% segmented neutrophils. Further hepatitis workup yielded antinuclear antibodies positive for nuclear, speckled pattern with 1 : 1280 titer, actin antibodies IgG 57 units, and negative viral hepatitis panel for hepatitis A, B, and C. Abdominal ultrasound showed cirrhosis with hepatosplenomegaly and trace abdominal ascites.\nTwo sets of blood cultures obtained on hospital day 0 were negative. Intravenous ceftriaxone was started after collection of the initial blood cultures. Two additional anaerobic blood culture bottles obtained on day 2 of hospital stay were positive for Veillonella atypica, identified using MALDI-TOF (). Repeat blood cultures after 2 days of intravenous ceftriaxone were negative. The infectious disease team recommended discontinuing IV ceftriaxone as repeat cultures were negative and the patient had completed a 7-day course of ceftriaxone. Transthoracic echocardiogram was negative for valvular lesions. Liver biopsy obtained on hospital day 8 demonstrated bridging fibrosis and was consistent with alcoholic hepatitis with cholestasis (Figures and ).\nHospital course was complicated by hemodynamic instability and acute encephalopathy on day 3 and 4, where patient was tachycardic to 120 beats per minute, tachypneic to 30 shallow breaths per second, and febrile to 38.3°C. The patient's mental status was waxing and waning; there was a concern for sepsis, grade II hepatic encephalopathy, and alcohol withdrawal. Hemodynamic instability and mental status improved with IV lorazepam and lactulose, and the patient was subsequently discharged on hospital day 9. After confirmation of alcoholic hepatitis on liver biopsy, the patient started prednisolone 40 mg oral daily on day 7 after hospital discharge due to difficulty obtaining the prescription.\nPatient was evaluated in outpatient hepatology clinic 7 days after prednisolone therapy (14 days after hospital discharge). Pertinent labs showed a white blood cell count of 23.9 K/mm3, sodium of 123 mmol/L, and potassium of 2.9 mmol/L. Prothrombin time and total bilirubin had increased to 23.4 sec and 20.2 mg/dL, respectively. Calculated Lille score on day 7 of treatment was 0.577 and suggestive of treatment failure of alcoholic hepatitis. The patient was sent to the emergency room after the clinic visit for tachycardia and concern for sepsis. He was then readmitted to the hospital for further management. Repeat blood cultures and ascitic fluid culture on admission were negative. The patient was deemed a poor transplant candidate due to continued alcohol use and non-United States citizen status. After appropriate counseling, he left the hospital against medical advice to be home with family.\nDuring a phone follow-up 3 months after discharge, the medical team was informed that the patient was deceased.
