Abstract:
Very few reports have described giant pseudomeningoceles ≥ 8 cm in diameter. We report this case of the biggest giant pseudomeningocele at the unusual cervicothoracic level. A 59 year old man who underwent cervicothoracic laminectomy had a giant pseudomeningocele detected and the lesion gradually grew to about 15 cm in diameter by 2 years postoperatively. Cerebrospinal fluid leak closure was performed and the postoperative course was favorable. We present this case, review the literature and discuss the size and portion, mechanism of formation, symptoms and treatments of giant pseudomeningocele.
Insights
This study presents the largest giant pseudomeningocele case (15 cm) at the cervicothoracic level following laminectomy. Successful cerebrospinal fluid leak closure led to a favorable outcome.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Radiology
Background:
- Giant pseudomeningoceles (≥ 8 cm) are rare, with few documented cases.
- This report details an exceptionally large pseudomeningocele at the cervicothoracic junction.
Purpose of the Study:
- To report the largest giant pseudomeningocele case to date.
- To review literature on giant pseudomeningoceles regarding size, formation, symptoms, and treatment.
Main Methods:
- Case report of a 59-year-old male post-cervicothoracic laminectomy.
- Surgical intervention for cerebrospinal fluid leak closure.
- Literature review on giant pseudomeningoceles.
Main Results:
- A 15 cm giant pseudomeningocele was detected 2 years postoperatively.
- Successful cerebrospinal fluid leak closure resulted in a favorable clinical course.
Conclusions:
- Giant pseudomeningoceles, though rare, can reach significant sizes.
- Prompt diagnosis and surgical management of cerebrospinal fluid leaks are crucial for favorable outcomes.
