The case involved a 33-year-old woman diagnosed with an enlarged lymph node and Lyme’s disease. In fact, both diagnoses were incorrect. A general surgeon in 2011 found that the patient did not have an enlarged lymph node In March 2011 and a subsequent CT scan confirmed that finding.
The patient was referred to an ENT surgeon who, nevertheless, recommended a lymph node biopsy in August 2011. While performing the procedure, the surgeon cut across her spinal accessory nerve, an important nerve that supplies the neck and shoulder muscles.
