Background:
Here, we report a patient who presented with both symptomatic acromegaly and symptomatic Chiari I malformation (CM1) with a C2-T5 syrinx.
Case description:
A 63-year-old female presented with bilateral arm dysesthesias and back pain. For approximately the past 30 years, she had chronic signs of acromegaly (i.e. an enlarged forehead, jaw, and nose, and enlarged hands and feet). When the cervical magnetic resonance showed a CM1 (tonsillar herniation) with C2-T5 syringomyelia, she underwent foramen magnum decompression and C1 posterior arch resection. Postoperatively, she was asymptomatic. The added finding of a growth hormone (GH)-producing pituitary lesion was treated medically with endocrine therapy, as she had incidentally required surgery/chemotherapy for a newly diagnosed colon cancer.
Conclusion:
Symptomatic CM1, syrinx, and acromegaly may occur together. Appropriately treatment may include a suboccipital decompression, and C1 arch resection surgery, followed by either surgical or medical treatment for the GH-producing pituitary adenoma.
