Supplementary Material for: An Unusual Presentation of Hearing Impairment in an Adult with Pineal Region Germinoma: A Case Report

Tumors of the pineal region typically present with symptoms and signs of mass effect and increased intracranial pressure. However, although rare and can be overlooked, hearing impairment is a potential clinical finding in these cases. The authors describe a 24-year-old male who presented to the Emergency Room complaining of bilateral hearing impairment. Brain computed tomography showed a pineal region tumor. Histopathological examination demonstrated features consistent with germinoma. This case reports a rare presentation rarely seen in the literature and in practice as evident by the conducted literature review. Therefore, we highlight the importance of considering hearing impairment as a presenting symptom of pineal region tumors since prompt recognition and intervention, as demonstrated in this case, can lead to successful outcomes.

松果体区肿瘤通常以占位效应与颅内压增高的症状及体征为典型临床表现。然而，尽管听力受损较为罕见且易被漏诊，但其却是此类病例中潜在的临床异常表现之一。本文作者报告1例24岁男性患者，因双侧听力受损前往急诊就诊。头颅计算机断层扫描（CT）提示其松果体区存在占位性肿瘤。组织病理学检查结果符合生殖细胞瘤的病理特征。经本次文献回顾证实，该病例的罕见临床表现在临床实践及既往文献中均极为少见。因此，本文强调需将听力受损纳入松果体区肿瘤的首发症状鉴别清单，因如本例所示，及早识别并采取干预措施可获得良好治疗结局。
