How do you treat Pseudomeningocele?
A combined treatment protocol involving open revision surgery for extirpation of the pseudomeningocele, repair of dural tears, and implantation of a subarachnoid catheter for drainage is safe and effective to treat giant pseudomeningoceles.
What does a Pseudomeningocele feel like?
A pseudomeningocele can cause symptoms of postural headache, blurry vision, dizziness, diplopia, photophobia, tinnitus, back pain, leg pain and radicular symptoms, nausea, and vomiting, and in a rare case, it has even caused tracheal obstruction.
Is a Pseudomeningocele serious?
In some cases, compression of nerve roots and/or spinal cord may occur, causing symptoms. Spinal cord herniation in the pseudomeningocele is a rare but serious condition that requires urgent intervention.
What is lumbar Pseudomeningocele?
Pseudomeningocele is an extradural accumulation of cerebrospinal fluid (CSF) that extravasates through a dural opening [1]. The aetiology can be traumatic, congenital or iatrogenic [2, 3]. The incidence of pseudomeningoceles following lumbar spine surgery is uncertain, but is reported between 0.07% [4] and 2% [5].
What is considered a large pseudomeningocele?
A giant pseudomeningocele is defined as a lesion ≥ 8 cm in diameter[4] and only 17 cases of giant pseudomeningoceles (Table 1) have been reported in the literature[4,9,10-12]. Of these 17 cases, 11 patients were men (64.7%) and 6 were women (35.3%). The mean age of the patients was 39.7 years (range 19-68 years).
What is lumbar pseudomeningocele?
What is a Pseudomeningocele of the brain?
Pseudomeningoceles are abnormal collections of cerebrospinal fluid (CSF) that occur due to leakage from the CSF-filled spaces surrounding the brain and/or spinal cord as a result of trauma or surgery.
Is Pseudomeningocele an infection?
Background. Pseudomeningocele is an uncommon complication of spinal surgery [1–3]. It is an extradural accumulation of cerebrospinal fluid (CSF) in the soft tissue of the back that extravasates through the dural tear [4, 5].
What is considered a large Pseudomeningocele?
How are pseudomeningoceles treated?
Surgical procedures for treating pseudomeningoceles have been described [2,7,11-13]. In general, pseudomeningoceles are surgically explored and entered. Nerve roots are gently dissected free then reduced into the thecal sac if herniated into the pseudomeningocele cavity. Identification and removal of fistulous tracts is carried out.
What are the symptoms of pseudomeningocele?
Most of the patients with pseudomeningocele report headache. Sometimes the leakage may find it’s way to the spinal canal i.e. epidural space or in the introductory case i.e. subdural space. The most common cause reported behind pseudomeningocele is the cervical surgery.
Which tests are used to diagnose pseudomeningoceles?
A pseudomeningocele should be considered for patients with recurrent back pain, radicular pain, or a persistent headache after spinal surgery. Most authors consider MRI to be the most effective non-invasive diagnostic tool that can accurately assess the size and location of pseudomeningoceles.
Where to study for giant pseudomeningoceles in the US?
1 Department of Neurosurgery, University of California San Diego School of Medicine, San Diego, California. 2 Department of Plastic Surgery, University of California San Diego School of Medicine, San Diego, California. Background: Giant pseudomeningoceles are an uncommon complication of spine surgery.
