23 female patients complained of severe occipital headaches and dissociative sensory loss in form of lost hot sensation in left hand after giving birth to her child. MRI showed post fossa mass, tonsillar herniation and cervical syringomyelia. Patient underwent suboccipital decompression and mass excision. Histopathology indicated the mass is pilocytic astrocytoma. Later patient symptoms improved dramatically, and MRI showed resolution of syringomyleia 6 months after surgery.
Acquired Chiari malformation with secondary syringomyelia is a rare occurring condition due to posterior fossa space occupying lesions that causes tonsillar herniation and subsequent syrinx formation . Synringomyleia occurrence is still unclear till now starting from Dr. James Gardner theory of water hammer effect . Till the Oldfield theory of piston effect .
Female patient aged 23 years was doing well until she had given birth to her child, she underwent spinal anesthesia delivery was cesarean section. After delivery, she started to feel annoyed by occipital pain that increased in intensity and aggravated by straining and coughing (Figures 1-5). She then started to have dissociative sensory loss manifested mainly by lost hot sensation
in her right hand. Symptoms progressed dramatically in period of 4 months. She had Cranio-cervical MRI showed Posterior fossa
space occupying lesion associated with tonsillar herniation and cervical syringomyelia that mostly aggravated by lumbar puncture
during spinal anesthesia. Patient underwent mass excision and
suboccipital craniectomy and the space occupying lesion was Pilocytic astrocytoma. With post-operative improvement in her symptoms with remarkable recovery at 6 months follow up. MRI at 6 months’ follow-up showed complete resolution of the syringomyelia (Figures 6-10).
