Intracranial arachnoid cysts are rare cystic-appearing intracranial masses. In rarer cases, the arachnoid cysts originate from brain parenchyma, which is defined as intracerebral arachnoid cyst. Here, we present a patient younger than 2 years with massive intracranial arachnoid cysts (one of which was intracerebral arachnoid cyst), whose clinical symptoms included megacephaly and limb weakness. Ommaya reservoir implantation and repeated aspiration of the intracerebral cyst fluid were performed. The symptoms gradually improved, and the intracerebral arachnoid cyst gradually disappeared during 13 months of follow-up. The case highlights the potential of Ommaya reservoir implantation in the treatment of intracerebral arachnoid cyst, especially for young patients. We also reviewed the published literatures concerning the rare condition, including the mechanisms for its pathogenesis and enlargement.
颅内蛛网膜囊肿是一种罕见的、呈囊肿样的颅内肿块。在更罕见的情况下，蛛网膜囊肿起源于脑实质，这被定义为脑内蛛网膜囊肿。在此，我们报告一名2岁以下患有巨大颅内蛛网膜囊肿（其中一个为脑内蛛网膜囊肿）的患者，其临床症状包括巨头畸形和肢体无力。进行了Ommaya储液囊植入及反复抽吸脑内囊液的操作。在13个月的随访期间，症状逐渐改善，脑内蛛网膜囊肿逐渐消失。该病例突出了Ommaya储液囊植入术在治疗脑内蛛网膜囊肿方面的潜力，尤其是对于年轻患者。我们还回顾了关于这种罕见病症的已发表文献，包括其发病机制和增大的机制。
