ABSTRACT:
Metastasis to the pituitary is very rare. Thyroid
carcinoma as a primary source of pituitary metastasis is uncommon. Pituitary
metastasis is common in posterior pituitary. Metastasis can also occur to
anterior pituitary with varied presentations. Case Description: A 47-year-old
lady presented with galactorrhoea, ptosis, diminished vision of the right eye,
and headache from 6 months. She had a pituitary macroadenoma with suprasellar,
para-sellar and infrasellar extension on evaluation. She underwent initial transnasal
trans-sphenoidal decompression followed by pteronial craniotomy with
decompression of the residual tumour. The histopathology was metastatic tumor
of sella. Further evaluation showed a thyroid nodule and bilateral lung
nodules. With suspicion of a primary thyroid malignancy, total thyroidectomy
was performed and biopsy report of the thyroid showed follicular carcinoma.
Conclusion: Metastasis to the pituitary can be a rare presentation of thyroid
cancer. It may masquerade a pituitary adenoma. Key-words: Sella, Pituitary
metastases, Parasellar, Suprasellar, Diabetes Insipidus, Thyroid.
Key Messages: A high index of clinical
suspicion is needed to diagnose pituitary metastases. A rapidly appearing mass
in sella with parasellar, suprasellar extensions, diabetes insipidus at onset,
sudden onset ophthalmoplegia, and a normal sized sella favor a diagnosis of
pituitary metastasis.
