Electromyography (EMG) showed sensorimotor axonal polyneuropathy in lower extremities, as well as continuous motor unit activity and co-activation of agonists and antagonist muscles (Figure 2), typical for SPS.
Chest CT showed a 4-cm left-breast mass with central necrosis.

A computed tomography (CT) scan of the chest, abdomen, and pelvis showed a 4-cm left-breast mass with central necrosis and multiple large left axillary lymph nodes (Figure 3).
Left panel: Core biopsy section from the left-breast mass shows invasive ductal carcinoma (x400 magnification). Right panel: Core biopsy section from the left infraclavicular lymph node shows metastatic breast carcinoma cells in the lymphoid tissue (x200 magnification).
