松果体生殖细胞瘤在颅内原发肿瘤中虽不多见,但在松果体部位的肿瘤发病中却占首位。国内杨氏首先报告1例,近年来陆续有少量报道。由于肿瘤恶性程度高,易在脑室系统远处形成转移病灶并侵犯邻近组织,引起复杂的临床表现,诊断较困难。为了提高对本病的认识,现将我院经病理证实的2例松果体生殖细胞瘤(合并有下丘脑垂体功能紊乱)病例报告如下:例1 住院号223535,男性,16岁。 Although pineal germ cell tumors are rare in primary intracranial tumors, they account for the majority of tumors in the pineal gland. Yang first reported 1 case in China, one after another in recent years a small amount of coverage. Due to the high degree of malignancy of tumors, it is easy to form metastatic lesions in the distant ventricular system and invade the adjacent tissues, causing complicated clinical manifestations, making diagnosis more difficult. In order to improve the understanding of the disease, now in our hospital confirmed by pathology in 2 cases of pineal germ cell tumors (with hypothalamic pituitary dysfunction) cases are reported as follows: Example 1 Hospitalization 223535, male, 16 years old.
