Een vrouw met tintelingen in de hand

A 57-year-old woman presented herself in the plastic surgery department’s outpatient clinic at our hospital. She had been experiencing a tingling sensation of the first three digits of the left hand. Our first differential diagnosis was a classic carpal tunnel syndrome. Physical examination showed a minor prominence, which provoked the same tingling sensation when given tactile pressure. Diagnostic MRI showed that the prominence seemed like a peripheral nerve tumour of the median nerve. Primary excision was performed, after which the symptoms disappeared without lasting effects. Pathologic investigation confirmed the diagnosis of schwannoma of the median nerve.
