[Endocrine abnormalities in a patient with borderline personality disorder--case 8/2014].
Deutsche Medizinische Wochenschrift 2014 December
HISTORY AND ADMISSION FINDINGS: We report on a 44-year-old woman who was treated for borderline personality disorder in the Department of Psychiatry. In addition, symptoms of hyperthyroidism (anxiety, weight loss, hyperdefecation) were noticeable. Thyroid stimulating hormone (TSH) was marginally elevated, free triiodothyronine (T3) and free thyroxine (T4) were clearly elevated. Hence, the patient was transferred to the Department of Endocrinology.
INVESTIGATIONS: Thyroid ultrasound revealed a diffuse goiter with a total volume of 24,8 ml. Antibody screening did not show elevated titers. The thyrotropin releasing hormone (TRH) test depicted a blunted TSH response. Serum levels of free glycoprotein hormone alpha-subunit, prolactin and insulin-like growth factor 1 were increased.
DIAGNOSIS, TREATMENT AND COURSE: In cranial magnetic resonance imaging (MRI), a hypointense lesion on the left side of the anterior pituitary gland was detected indicating a thyrotropin-secreting microadenoma with concomitant secretion of prolactin and possible secretion of human growth hormone (HGH). A thyreostatic therapy was initiated aiming at euthyreosis. For symptom control, betablockers were administered. Subsequently, the patient underwent an uncomplicated transsphenoidal resection. Histological examination confirmed the diagnosis of a pituitary adenoma with expression of TSH, prolactin and HGH. As expected, thyroid hormones declined afterwards.
CONCLUSIONS: TSHoma is rare. Diagnosis is confirmed by endocrinological testing and cranial imaging. Therapeutic options comprise transsphenoidal adenomectomy, drug therapy (somatostatin analogues, dopaminergic agonists) and irradiation. Resistance to thyroid hormones should be included in the differential diagnosis.
