Abstract
Meningeal carcinomatosis occurs in 1%–5% of patients with breast cancer. Early diagnosis and aggressive treatment of neurologic involvement are important factors of prognosis. We report a case of a 52-year-old woman who was affected by bilateral breast carcinoma treated with surgery and chemotherapy. Six years after she had become asymptomatic, X-rays showed lumbar spine metastases which were treated with radiotherapy. After 1 year she began to suffer form lower limb paresthesias, unsteadiness and unstable gait. Clinical examination showed lower limb sensory ataxia with lack of knee and ankle reflexes, and hypopallesthesia from the iliac spine to the foot. Spinal magnetic resonance imaging (MRI) with contrast agent revealed no medullar compression. Electromyography disclosed bilateral involvement of L4-L5-S1 roots and corresponding paraspinal muscles. Sensory and motor conductions were normal. Cerebrospinal fluid (CSF) examination showed the presence of neoplastic cells, confirming the diagnosis of meningeal carcinomatosis. Our patient underwent 9 cycles of intrathecal methotrexate therapy (25 mg/cycle) with improvement of ataxia and relief of paresthesias. One year later, CSF examination is still negative. We point out the importance of electrodiagnostic studies and CSF examination in the early documentation of root involvement in cancer patients, when computed tomography, MRI and myelography are normal. Early diagnosis may lead to effective therapy which prolongs survival.
