Abstrakt:	Summary: A 17-year-old lady presented with primary amenorrhoea, headache, nausea and lethargy. She had delayed pubertal development that also includes under-developed breast (Tanner Stage 2). Hormonal investigations showed a high serum prolactin level of 1 680 000 mIU/L (normal value: 45-375 mIU/L), with low oestradiol, progesterone, follicular-stimulating hormone and luteinizing hormone. Early morning cortisol level was 206 nmol/L (normal value: >450 nmol/L), thyroxine was 7.5 pmol/L (normal value: 9.0-24.0 pmol/L) with TSH 5.091 mIU/L (normal value: 0.4-4.5 mlU/L). A pituitary MRI showed a 2.7 (AP) × 3.7 (W) × 4.6 cm (CC) macroadenoma, with invasion into the left cavernous sinus and encasement of cavernous portion of the left internal carotid artery. MRI pelvis showed absent uterus, cervix and 2/3 upper vagina confirming Mullerian hypoplasia. Cytogenetics showed 46XX. These findings were suggestive of Mayer-Rokitansky-Kauser-Hauser (MRKH) syndrome with the presence of a pituitary macroprolactinoma and panhypopituitarism. She was treated with hydrocortisone, levothyroxine and cabergoline. Repeated MRI showed a reduction in tumour size by approximately 50%. This case illustrated a rare coexistence of these two conditions, being only the third reported case in the world. In addition, this would be the first case of a functioning pituitary adenoma in a patient with MRKH syndrome. Learning Points: Comprehensive hormonal and radiological investigations are important in the management of a young patient with primary amenorrhoea. Coexistence pathology of two separate pathologies should be considered in patient presenting with primary amenorrhoea. Early diagnosis of MRKH or any disorders of sex development should be treated early, providing pharmacological, surgical, psychological and emotional support to the patient and reducing risk of associated complications. Abnormal pituitary hormones, particularly panhypopituitarism, would impose greater impact not only psychologically but also metabolically leading to cardiovascular, morbidity and mortality risks in this patient if not treated early. A multidisciplinary approach is necessary for patients presenting with MRKH to ensure appropriate treatments and follow-up across the lifespan of the patient.
