A Rare Case of Refractory Mycobacteroides Abscessus Otomastoiditis in an Immunocompetent Child: A Multidisciplinary Treatment Approach
Bibliographic record
Abstract
This case report details a rare and severe presentation of refractory otomastoiditis caused by Mycobacterium abscessus in an immunocompetent pediatric patient who presented with a 1-month history of left ear pain, swelling, and fever unresponsive to antibiotics. Computed tomography imaging was suggestive of coalescent otomastoiditis, and she underwent urgent left mastoidectomy, subperiosteal abscess drainage, and myringotomy with tube insertion, followed by conventional antibiotic management. Despite these interventions, she remained symptomatic and cultures revealed M. abscessus 1 week later. Multidisciplinary management involved serial microdebridement and prolonged multidrug antimicrobial therapy with shared decision-making between otolaryngology, infectious diseases, and international experts. Pharmacological management was complicated by adverse effects including aminoglycoside-induced hearing loss, myelosuppression, and gastrointestinal intolerance requiring drug substitutions. Eighteen months after initial presentation, revision mastoidectomy, canaloplasty, mastoid obliteration, tympanoplasty, and ossiculoplasty were performed for the eradication of residual disease and reconstruction. At follow-up, there was no disease recurrence although left-sided moderate-to-severe mixed hearing loss persisted. This case highlights the importance of early recognition and coordinated medical-surgical interventions in atypical presentations of mastoiditis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
