RESUMO
Ossification of pseudomeningocele is a rare occurrence and is one of the rare complications of ventriculoperitoneal (VP) shunt malfunction. We report a case of 12-year-old boy who came with features of raised intracranial pressure following shunt malfunction which was placed as a treatment to the aqueductal stenosis. Computed tomography showed ventriculomegaly and hypodense collection in the occiput with posterior rim of calcification. The findings were confirmed on histopathology. Although ossified pseudomeningocele is a rare entity following VP shunt placement, it should be suspected if patients present with aggravated symptoms, especially if there is shunt malfunction as the treatment option varies with the presence or absence of resultant symptoms and ossification.
RESUMO
BACKGROUND: Intramedullary epidermoid cyst (IEC), typically associated with spinal dysraphism, is rare, with fewer than 80 such cases reported in the literature. Here we present an adult with an IEC without spinal dysraphism. CASE DESCRIPTION: A 41-year-old female presented with the gradual onset of a progressive spastic paraparesis attributed to a magnetic resonance imaging (MRI)-documented D8-9 intramedullary lesion. Following microsurgical excision of the IEC, she fully recovered. CONCLUSION: IECs are rare lesions, typically found in conjunction with spinal dysraphism. Utilizing MRI studies to document the lesion location, gross total microsurgical excision is the procedure of choice. Early excision of these benign lesions maximizes functional recovery.
