Background: Goiters are commonly benign, but
cases of malignancy can develop. Thyroid cancer is
known to be commoner in whites than in blacks and in
females than in males. Bone metastasis is a common
occurrence and may be the initial manifestation in a
small subset. We hope to determine the incidence and
the cervical radiographic patterns of thyroid cancer
amongst goiter population in Nigeria.
Method: Surgical, histological and radiographic
findings in patients with goiter who had thyroidectomy
in our hospital from 1999 to 2006 were reviewed.
Those with proven cancer were analyzed for sex, age
and radiographic changes using SPSS 11.0 for
Results Thirteen (8.2%) cases out of the 160 goiters
were malignant and distant metastases were present
in 1.3% at presentation. The histological sub-types of
malignant goiters were follicular (5.0%), papillary
(1.9%) and poorly differentiated or anaplastic thyroid
carcinoma (1.3%). As much as 30% of thyroid cancers
demonstrated calcification on plain neck radiograph,
which were commonly scattered or diffused.
Conclusions: Carcinomatous goiters occurred in
9.3% of the goiter population studied with
predominance of follicular variant. Surgery remains the
main stay but was inappropriate in about 1.2 % of
population with goitre. Aside evidence of bony
destruction, TC should be suspected in goiters with
mixed (diffused or scattered) calcifications.
