Conclusion
GCT is rare in the clinic. The clinical manifestations and imaging examination for GCT are not specific, and thus, it is easy to misdiagnose. Generally, GCTs are benign, and the prognosis of surgical resection is good, with less recurrence, but a small number of GCTs can be malignant. Close follow-up should be performed after the operation. Similar cases are rare, and few related literature have been reported. The diagnosis, treatment, and prognosis evaluation of GCT should be further studied.
