Abstract: We present a rare clinical case. Inflammatory myofibroblastic tumors (IMT) are extremely rare neoplasms of unknown etiology and most commonly found in lungs and gastrointestinal tract. A rare clinical case of the thyroid IMT occurred in a 50-year-old lithuanian female patient with clinical manifestation of breathlessness, dry cough, hemoptysis, neck mass, arrhythmia and loss of consciousness. Because of elevated D dimers values, pulmonary artery thromboembolism was suspected and CT scan was performed. CT showed no pulmonary embolism, but revealed a large tumor in the neck. After patient was investigated in cardiology department to exclude sick sinus syndrome, fine needle aspiration cytology of thyroid nodus was done with non-diagnostic results. Thyroid scintigraphy showed cold node suggesting maligancy. All symptoms and findings indicated the need of surgical treatment. The patient underwent total thyroidectomy. Histopathology analysis revealed two separative tumors: follicular carcinoma and thyroid inflammatory myofibroblastic tumor. Because of folicular carcinoma the patient was treated with radioiodine. She was comfortable after treatment with thyroid hormone replacement therapy. We managed to find only 20 cases of this type of tumor located in thyroid reported in the literature. And we did not find reports with two concomitant thyroid tumors including IMT.
