Unusual presentation of gestational trophoblastic neoplasm: Report of two cases

Abstract: Gestational Trophoblastic Neoplasm (GTN) is among rare human tumors which can be observed with widespread metastasis. Two young patients with emergent neurologic symptoms with no gynecological problems are presented in this report. GTN was later diagnosed in both cases with brain metastasis. The first case: A 22 years old patient, admitted to the infectious disease ward, with probable diagnosis of Encephalitis. After brain CT scan and measurement of β human chorionic gonadotropin (βhCG), GTN with brain metastasis was confirmed. The second case: A 33 years old patient who underwent craniotomy due to hemorrhagic brain tumor in neurosurgery department. Brain metastatic GTN was confirmed by histological examinations. Both cases received multiagent chemotherapy concurrent with whole brain irradiation of 3000 cGy in 10 fractions (F) within a period of 2 weeks, and chemotherapy was continued for additional course. The patients were both well after about 22 months. Diagnosis of GTN should be considered in any woman of reproductive age.
