PLATYBASIA AND BASILAR INVAGINATION PRESENTING AS CEREBROVASCULAR ACCIDENT Abstract The congenital and acquired deformities of thecraniovertebral junction (basilar invagination,basilar impression, or platybasia) can present in the form ofslowly progressive [wwjournals.com]

• Asymptomatic

  In most cases, subluxation less than this is asymptomatic. Lateral x-rays taken in extension and flexion are used to demonstrate AAS. [dizziness-and-balance.com]

  Patients may be asymptomatic or complain of headaches, neck pain, cough, trigeminal neuralgia, limb weakness, altered muscle reflexes, quadriparesis, nystagmus, and ataxia. [rrnursingschool.biz]

  Although asymptomatic patients are often followed conservatively, many authors favor surgery even if no symptoms of cord compression are evident in rheumatoid patients. [neuroradiologyonthenet.blogspot.com]

  As an isolated finding, platybasia is not clinically important, and most patients are asymptomatic ( 13 ). When the basal angle is measured on lateral skull images, accurate X-ray techniques are essential for correct angles. [ajnr.org]

  While it can be closely associated with basilar invagination and basilar impression, in isolation it is asymptomatic and essentially is a misused term when used to describe congenital defects. [statpearls.com]

• Collapse

  Bone collapse at the craniocervical junction can cause sudden death. Unlike pykno-dysostosis, a disorder with overlapping features, the mandibular angle is not missing in Hajdu-Cheney syndrome. [rrnursingschool.biz]

• Prolonged Immobilization

  Therapeutic strategies vary from prolonged immobilization to posterior fossa or ventral brain stem decompression with occipitocervical fusion. However, the results are not uniformly satisfactory (Sawin and Menezes 1997). [rrnursingschool.biz]

• Painful Cough

  Patients may be asymptomatic or complain of headaches, neck pain, cough, trigeminal neuralgia, limb weakness, altered muscle reflexes, quadriparesis, nystagmus, and ataxia. [rrnursingschool.biz]

  These abnormalities can result in neck pain; syringomyelia; cerebellar, lower cranial nerve, and spinal cord deficits; and vertebrobasilar ischemia. Diagnosis is by MRI or CT. [merckmanuals.com]

• Severe Osteoporosis

  Indeed, basilar impression can complicate the course of any disease associated with severe osteoporosis, os- Fig. 1.37. Basilar invagination in a 32-year-old woman. [rrnursingschool.biz]

• Diplopia

  The symptoms may also include clumsiness, numbness along one side of the body, unsteadiness of the gait, vertigo, weakness of one side of the body, loss of control of bowel and bladder, diplopia (double vision), periodic or constant cramping pain of one-sided [xpertdox.com]

  The most frequent ocular symptoms are: retro-orbital headache, diplopia, photopsia, blurred vision, and photophobia. [bmcmusculoskeletdisord.biomedcentral.com]

• Short Neck

  Klippel-Feil syndrome type II is massive fusion of two of seven cervical vertebrae associated with short neck and low hair line. [ncbi.nlm.nih.gov]

  She had blue sclera and short neck ( figure 1 ), right hypoglossal palsy, bilateral pyramidal tract signs, and gaze-evoked nystagmus. [n.neurology.org]

  A short neck, craniofacial asymmetry, and kyphoscoliosis are common associated features. The foramen magnum is often deformed to varying extents. [rrnursingschool.biz]

• Cleft Lip and-or Palate

  However, young adults with repaired unilateral cleft lip and palate still have more obtuse cranial base angles than the control group [ 23 ], suggesting that no effect of surgical correction overcomes a congenitally obtuse angle. [e-aps.org]

• Lhermitte Sign

  Lhermitte's sign (a tingling on neck movement, flexion in this case) can be demonstrated at any stage. A plain lateral x-ray, with odontoid views, is a good place to start, but is not 100% sensitive (Riew, Hilibrand et al. 2001). [dizziness-and-balance.com]

  Tingling down the back, often into the legs, with neck flexion (Lhermitte sign) may occur. Uncommonly, pain and temperature senses (spinothalamic tract function) are impaired in a stocking-glove pattern. [merckmanuals.com]

• Hyperreflexia

  According to Sawin and Menezes series in persons with osteogenesis imperfecta (1997), symptoms and signs included headache (76%), lower cranial nerve dysfunction (68%), hyperreflexia (56%), quadriparesis (48%), ataxia (32%), nystagmus (28%), and scoliosis [dizziness-and-balance.com]

• Spastic Quadriplegia

  Spastic quadriplegia can result from platybasia. Basilar invagination or compression of posterior fossa structures may lead to cerebellar or brainstem compressive syndromes. [emedicine.medscape.com]

• Limb Weakness

  Patients may be asymptomatic or complain of headaches, neck pain, cough, trigeminal neuralgia, limb weakness, altered muscle reflexes, quadriparesis, nystagmus, and ataxia. [rrnursingschool.biz]

Treatment: Unless there is impingement or compression of nerve roots or other neural tissue, no treatment is specifically indicated for platybasia; however, neural compression requires optimal treatment. [neurosurgery.ucla.edu]

Early recognition and implementation of aggressive treatment are important if irreversible neurological deficits are to be avoided. [ncbi.nlm.nih.gov]

The etiology of VPD in 22q11DS is multifaceted [ 2 ] and is likely to be a sum of many factors. Our findings indicate that platybasia does not play a prominent role in VPD. [e-sciencecentral.org]
