Key Takeaway

Note that mNGS can aid in identifying atypical pathogens like Aspergillus flavus to guide targeted antifungal therapy.

This case report and literature review describes a clinical scenario involving a 74-year-old immunocompetent male with grade II degenerative lumbar spondylolisthesis who presented with an Aspergillus flavus infection. The patient received staged combined antifungal therapy, consisting of intravenous and oral voriconazole, alongside surgical management including radical debridement, internal fixation revision, and bone graft reconstruction.

The primary outcome was the eradication of the Aspergillus flavus infection, which was achieved successfully with no recurrence at a 12-month follow-up. The secondary outcome of pain relief was also reported as marked at the 12-month mark. Molecular next-generation sequencing (mNGS) was utilized to identify the specific pathogen in all tissue samples.

The authors note that mNGS serves as a valuable adjunctive diagnostic tool when conventional examinations are negative, particularly for atypical infections. However, the findings are limited by a single-case and single-center design, which precludes statistical generalizability. The report suggests that precise diagnosis via mNGS can facilitate individualized management of refractory spinal surgical site infections.

How this fits prior evidence

This case report addresses a gap in managing specific fungal pathogens in spinal infections. It complements previous evidence regarding voriconazole for other fungal conditions, such as the use of voriconazole and micafungin for Aspergillus lentulus infection in a patient with CGD, and the use of voriconazole for endogenous fungal endophthalmitis.

Imagine living with a persistent, painful infection deep within your spine. For many patients, these infections are hard to treat because they are hidden from standard tests. In this case, a 74-year-old man suffered from an infection caused by a fungus called Aspergillus flavus in his lower back.

Doctors used a two-part approach to treat him. They performed extensive surgery to clean out the infected tissue and stabilize his spine with hardware. At the same time, he received a staged course of voriconazole, an antifungal medicine given both through an IV and as a pill. This combined strategy successfully cleared the fungus from his body.

At a 12-month follow-up, the man showed no signs of the infection returning and reported significant relief from his pain. While this was a single case study, it highlights how advanced testing can identify specific fungi that standard tests might miss, allowing doctors to create a precise treatment plan for difficult spinal infections.

What this means for you:

Combining surgical cleaning with targeted antifungal drugs successfully cleared a deep fungal spine infection.

Common questions

What kind of infection was treated?

The patient had an infection caused by a fungus called Aspergillus flavus. This specific type of fungus was identified in his tissue samples using advanced testing, which helped doctors confirm the exact cause of the problem and provide a more targeted treatment plan.

How did the medical team treat the spine infection?

The treatment involved two main parts. First, surgeons performed radical debridement to clean out the infected tissue and used internal fixation to stabilize the bone. Second, the patient received a staged course of voriconazole, an antifungal medication given both through an IV and as an oral pill.

Was the treatment successful for the patient?

Yes, the results were positive. At the 12-month follow-up, the infection was completely eradicated with no signs of it coming back. Additionally, the patient experienced marked relief from his pain after the combined surgery and medication treatment.

Surgical site infection following lumbar internal fixation and fusion is predominantly bacterial. Aflatoxin-associated discitis is extremely rare in immunocompetent patients and often results in delayed diagnosis and inadequate empirical antimicrobial treatment. This report presents a 74-year-old immunocompetent male patient who underwent elective posterior lumbar interbody fusion for grade II degenerative lumbar spondylolisthesis and developed intractable low back pain 3 months postoperatively. Despite multiple courses of broad-spectrum antibiotic therapy administered at two external hospitals, his symptoms did not resolve. Conventional bacterial, mycobacterial, and fungal cultures, as well as histopathological examination of percutaneous biopsy and intraoperative specimens, yielded negative microbial results. Metagenomic next-generation sequencing (mNGS) specifically identified Aspergillus flavus in all tissue samples, confirming the etiological diagnosis of fungal discitis. The patient received staged combined antifungal and surgical management. Intravenous voriconazole was used for induction therapy, followed by radical debridement of infected spinal tissue, internal fixation revision, and bone graft reconstruction. Oral voriconazole was prescribed for 3 months of postoperative maintenance therapy. A 12-month follow-up showed marked pain relief, and serial imaging and laboratory tests confirmed complete eradication of the infection with no recurrence. This case is systematically compared with previously reported Aspergillus spinal infections in immunocompetent hosts. mNGS serves as a valuable adjunctive diagnostic tool for clinically suspected atypical infections when conventional examinations are negative. Although limited by a single-case, single-center design without statistical generalizability, this report expands clinical recognition of post-fusion fungal discitis in immunocompetent patients and provides practical evidence for precise diagnosis and individualized management of refractory spinal surgical site infections.
