Primary Yolk Sac Tumor of Bilateral Basal Ganglia

Abstract: A primary intracranial yolk sac tumor (YST) is a type of germ cell tumor (GCT) and usually involves the pineal or suprasellar regions, as do other GCTs. Primary YST in the basal ganglia is not common, and bilateral basal ganglia involvement is even rarer. Early diagnosis is often difficult because of minimal or subtle findings without space-occupying lesions shown on neuroimaging during the early course of the disease. We report a case of primary intracranial YST encountered in the basal ganglia bilaterally an… Show more

“…The authors speculate that the serum α FP level will be the most useful marker for preoperative diagnosis. However, this value was measured before surgery in only 5 cases (23%) out of the previous cases of CNS yolk sac tumors located in unusual areas [5, 6, 10–12]. In our case, the preoperative serum α FP level, which was evaluated for the differential diagnosis of metastatic brain tumors along with other tumor markers, was extremely high, and the α FP level decreased after surgery.…”

“…Detailed descriptions of intracranial yolk sac tumors in the frontal lobe or the basal ganglia have been published for only 7 cases, including our case [410]. In all of the previous cases, the tumors developed in patients no older than 18 years; the present case is the first report of a yolk sac tumor in this location in a middle-aged patient.…”

“…7 Este último grupo acarreta um pior prognóstico. 6,7 Na presença de um tumor, em uma criança ou adulto jovem, localizado na linha média, deve ser considerada a hipótese de se tratar de um tumor de células germinativas. Deve então ser efetuada uma pesquisa de marcadores tumorais (alfafetoproteína e beta HCG) no sangue e/ou líquor.…”

“…Dada a raridade das histologias dos tumores de células germinativas não germinomas, nas revisões da literatura referentes ao prognóstico e sobrevida estes são muitas vezes agrupados na mesma categoria 7 , com sobrevida reportada de 45% aos 2 anos para este subgrupo de tumores. 8 Dos 19 casos descritos fora da linha média 1,6 à data das respectivas publicações, 4 pacientes tinham falecido em menos de 1 ano (em 4 casos, a sobrevida não foi descriminada). No que diz respeito às modalidades de tratamento complementar, 12 pacientes dos 19 casos foram submetidos a programas de quimioterapia (5 em conjunto com radioterapia).…”
