Schwannomas of the head and neck as well as brachial plexus primary tumors are both uncommon
entities, and combination of these conditions is quite rare. Schwannomas of the brachial plexus
are usually asymptomatic and they present as slowly enlarging masses in the supra- or infraclavicular
regions. Although imaging plays a routine role in the detection of these neoplasms, identification
of the nerve origin is not often feasible until the time of surgery. Definitive diagnosis is
based on histopathological features with presence of spindle-shaped Schwann cells. We report a
case of a middle aged woman with left lateral mid-neck mass, which based on the clinical findings,
was provisionally diagnosed as a painless lymphadenopathy. Ensuing excisional biopsy revealed
the brachial plexus as the origin of a tumor, which subsequently was confirmed to be a schwannoma
with microscopic evaluation. The course of disease was complicated with upper brachial
plexus injury which was recovered by sural nerve graft.
