A rare brain tumor in the subthalamic nucleus (STN) developed in a breast cancer patient, causing significant weight gain. This unusual case highlights potential neurological complications of advanced cancer.

Area of Science:

  • Neuro-oncology
  • Endocrinology
  • Radiotherapy

Background:

  • Locally advanced breast cancer requires comprehensive treatment, including chemotherapy and hormonal therapy.
  • Neurological complications can arise during or after cancer treatment.
  • The subthalamic nucleus (STN) is a critical brain structure involved in motor control and other functions.

Observation:

  • A 42-year-old woman with a history of locally advanced breast cancer presented with new-onset headaches post-chemotherapy.
  • MRI revealed a solitary mass in the left subthalamic nucleus (STN), extending into the thalamus and hypothalamus.
  • The patient declined biopsy and gamma knife treatment due to financial constraints.

Findings:

  • Palliative whole brain radiotherapy and hormonal therapy were initiated for the brain mass.

  • The patient experienced significant hyperphagia, leading to a 19 kg weight gain over 4 months.
  • The tumor's location in the STN, whether metastatic or primary, is exceptionally rare.

    • Implications:

    • This case underscores the importance of considering unusual neurological presentations in cancer patients.
    • The involvement of the STN and hypothalamus suggests potential disruption of appetite regulation pathways.
    • Further research is needed to understand the mechanisms and management of such rare brain metastases or primary tumors.
