INTRODUCTION Cauda equina secondary to metastatic follicular thyroid cancer of the lumbosacral area is a rare entity. CASE REPORT We report an unusual case of a 52-year-old male who presented with backache, lower limb weakness, and perianal numbness. A CT-scan of the lumbosacral area showed an enhancing mass at the L4, L5 and S1 vertebrae. Histopathology after excision revealed a metastatic t...

Ultrasonography (US) is the most commonly performed test used to visualize the thyroid. This examination is safe and readily available, hence it is very often carried out. Ultrasound observations allow the description of structural abnormalities of the thyroid gland evaluated in whole, or of nodules/focal lesions present in the thyroid. An ultrasound examination measures the acoustic density of...

DIAGNOSIS Management of differentiated thyroid cancer begins with diagnosis, usually surgical excision, and initial staging postoperatively. Diagnosis is achieved by history and exam, thyroid function tests and calcitonin (CT) assay, ultrasound, most frequently fine needle aspiration (FNA), sometimes isotope scans radiographs, computed axial tomography (CAT) scans or magnetic resonance imaging ...

Parathyroid carcinoma (PC) is a rare endocrine malignancy. The tumor is mostly functioning, causing severe primary hyperparathyroidism, with high serum calcium and parathyroid hormone (PTH) levels. Nonfunctioning PC is extremely rare. We report a 50-year-old male patient who was referred to our Department for a right thyroid nodule, incidentally detected on carotid Doppler ultrasound scan, with...

OBJECTIVE To determine the factors associated with thyroid cancer, focusing on first-degree family history and ultrasonography (US) features, in euthyroid asymptomatic patients with thyroid nodules. MATERIALS AND METHODS This retrospective study included 1310 thyroid nodules of 1254 euthyroid asymptomatic patients who underwent US-guided fine-needle aspiration biopsy between November 2012 and...

CONTEXT/OBJECTIVE Approximately 15% of thyroid cancer patients develop subsequent metastases. The clinical course of patients with metastatic thyroid carcinoma is highly variable. We hypothesized that the metabolic activity of metastatic lesions, as defined by retention of 2-[(18)F]fluoro-2-deoxyglucose (FDG), would correlate with prognosis. DESIGN/PATIENTS The initial FDG-positron emission t...

Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck r...
