M. Maruyama et al., Solitary brain metastasis from papillary thyroid carcinoma in a patient with depression: Report of a case, SURG TODAY, 30(9), 2000, pp. 827-830
Papillary carcinoma of the thyroid is a common thyroid malignancy with a re
latively good prognosis. However, distant metastases may develop and become
threatening, particularly to older patients, in a more aggressive manner.
We report herein the clinical, radiological, and pathological findings of a
patient with papillary thyroid carcinoma who had a solitary cerebral metas
tasis, The patient had been suffering from depression and had already under
gone a hemithyroidectomy for primary thyroid carcinoma, and was known to ha
ve metastatic thryoid carcinoma of the lungs and bone. After the removal of
the remnant thyroid gland prior to radioiodine (I-131) therapy, he develop
ed additional problems related to depression. Electroencephalography played
an important role in identifying suspected brain metastasis and computed t
omography demonstrated a space-occupying lesion in the left cerebral hemisp
here. Consequently, an early removal of intracranial mass could be performe
d without any further life-threatening complications. Moreover, after remov
al of the brain mass the patient's depression improved immediately without
the use of any antidepressants. This case report indicates the possibility
that a patient's depression might be associated with brain metastasis from
papillary thyroid carcinoma, and also suggests that an early diagnosis with
the appropriate surgical management of a brain metastasis followed by radi
oiodine therapy could be valuable for achieving a prolonged disease-free pe
riod.
