Gapped left occipital skull fracture with herniation of the left occipital leptomeninges and brain parenchyma through the bony defect. Left occipito-temporal area of encephalomalacia, likely sequel of old cerebral injury.
Case Discussion
Leptomeningeal cysts, also known as growing skull fractures, are an enlarging skull fracture that occurs near post-traumatic encephalomalacia. The term cyst is actually a misnomer, as it is not a cyst, but an extension of the encephalomalacia. Hence, it is usually seen a few months post-trauma.
