In February of 2013, during an attempt at a thoracic/lumbar myelogram/ct scan, it was discovered that I had a 12 cm, by 5 cm, by 2 cm calcified pseudomemingocele the entire length of the lumbar spine. It is palpable, painful to the touch, and may be leaking into the right side gluteal muscle. Back in 2009 I sustained the second of two fusion surgeries, an Alif/Plif from L1 to S1 with osteotomy at L4/5 which was the likely cause of the lesion. The GP was described by two radiologists as “fluid” and “undulating”.
I had consults with two neurosurgeons. One local and one from a large medical school and medical center where the surgeries were performed. Both said that a giant pseudomeningocele (GP) is a VERY COMMON OUTCOME of spinal fusion surgery. The symptoms that sent me to the doctor were pain and progressive weakness in my legs and the inability to stand up straight or walk without assistance of crutches. I believe these symptoms are at least partially due to the GP because of the large volume of nerve and muscle tissue that was bathed over 3+ years. BMP may be a factor as it was used during this surgery.
The NS recommended nothing, not even draining. Thoughts..............?
