A rare case of metastatic brachial plexopathy as an initial presentation of recurrent breast cancer mimicking shoulder disorder and peripheral nerve entrapment - A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe clinical manifestations of metastatic brachial plexopathy include pain, sensory loss, paresthesia, weakness, and reduced range of motion. These symptoms closely resemble those of shoulder disorders and peripheral nerve entrapment, which are commonly diagnosed in pain clinics, increasing the risk of misdiagnosis or delayed diagnosis, particularly in patients with a history of malignancy. CASE: A 51-year-old woman with a history of breast cancer in complete remission for 19 years presented with shoulder pain, arm weakness, and tingling in the fingers. Initial treatments for suspected cervical radiculopathy, shoulder disorders, and nerve entrapment were ineffective. Electromyography and nerve conduction studies revealed electrophysiological abnormalities consistent with left brachial plexopathy. Magnetic resonance imaging of the brachial plexus confirmed metastatic involvement. The patient is currently undergoing chemotherapy.
conclusionsClinicians must be vigilant of the possibility of malignancy in patients with a history of cancer and should pursue comprehensive diagnostic evaluations to exclude cancer recurrence.
