Abstract：
Intracranial dermoid cysts are unusual cystic tumors that are often benign, develop slowly, and are present from birth. They are made up of mature squamous epithelium and may house ectodermal features such as glands (apocrine, eccrine, and sebaceous). Dermoid cysts may be asymptomatic and can be detected incidentally during brain imaging for unrelated causes. Dermoid cysts tend to grow gradually and may eventually exert pressure on the brain and surrounding areas. Unfortunately, they can seldom burst, resulting in an unfavorable prognosis for the patient depending on the size, location, and clinical presentation. Headache, convulsions, cerebral ischemia, and aseptic meningitis are the most frequent symptoms. Magnetic resonance imaging (MRI) and computed tomography (CT) of the brain aid in accurate diagnosis and therapy planning. In some cases, the treatment consists of surgical monitoring with regular surveillance imaging. In other cases, surgery is needed, depending on the symptoms and the location of the cyst in the brain.
摘要：
颅内皮样囊肿是罕见的囊性肿瘤，通常是良性的，发展缓慢,从出生就存在。它们由成熟的鳞状上皮组成，可以容纳外胚层特征，例如腺体（顶腺，eccrine,和皮脂腺）。皮样囊肿可能无症状，并且可以在脑成像过程中偶然发现无关原因。皮样囊肿倾向于逐渐生长，并最终可能对大脑和周围区域施加压力。不幸的是,它们很少会爆裂，根据患者的大小，导致患者的预后不良，location,和临床表现。头痛,抽搐,脑缺血,无菌性脑膜炎是最常见的症状。大脑的磁共振成像（MRI）和计算机断层扫描（CT）有助于准确的诊断和治疗计划。在某些情况下,治疗包括手术监测和定期监测成像。在其他情况下,需要手术,根据症状和囊肿在大脑中的位置。
