Plain-English summary

A 4-year-old male Yorkshire terrier was diagnosed with primary hypothyroidism, which means his thyroid gland wasn't producing enough hormones. This condition was linked to leishmaniasis, an infection caused by a parasite. The vet confirmed the diagnosis through blood tests and a thyroid biopsy, which showed signs of the infection affecting the thyroid. Treatment for hypothyroidism typically involves hormone replacement therapy, which can help manage the symptoms and improve the dog's health.

Abstract

A case of primary hypothyroidism associated with leishmaniasis is described in a four-year-old, male Yorkshire terrier. Clinical diagnosis of hypothyroidism was confirmed by a low baseline serum tetraiodothyronine (T4), a reduced response to thyroid-stimulating hormone (TSH) stimulation, an increased serum TSH concentration, and scintigraphic thyroid gland examination. Examination of a thyroid biopsy showed many Leishmania amastigotes, both inside and outside of macrophages, together with signs of follicular atrophy.
