Syringobulbia is a term which has been clinically applied to brain stem symptoms or signs in patients with syringomyelia. Syringobulbia clefts are found on investigation or at necropsy caused by cutting outwards of the CSF under pressure from the fourth ventricle into the medulla. These should be differentiated from the ascending syringobulbia which may occur from upward impulsive fluid movements in a previously established syringomyelia. Clinical analysis of 54 patients suggests that bulbar features are most often found with neither of the above mechanisms but are due to the effects of pressure differences acting downward upon the hind-brain with consequent distortion of the cerebellum and brainstem, traction on cranial nerves or indentation of the brain-stem by vascular loops. The commonest symptoms in the 54 patients were headache (35), vertigo (27), dysphonia or dysarthria (21), trigeminal paraesthesiae (27), dysphagia (24), diplopia (16), tinnitus (11), palatal palsy (11) and hypoglossal involvement (11). Careful attention to hydrocephalus is advisable before craniovertebral surgery, but the decompression of the hindbrain and the correction of craniospinal pressure dissociation remains the mainstay of surgical treatment. The results of careful surgery are good, 45 of the 54 cases reported improvement. Most of the reported deterioration occurred in a few patients who did conspicuously badly.

Clinical, respiratory, and polysomnographic findings in three patients with syringomyelia and syringobulbia who developed severe respiratory complications are described. Neurological examination showed evidence of IXth and Xth cranial nerve involvement with dysphagia and dysphonia, but there were no complaints of serious sleep difficulties. Two patients died during sleep and the other was resuscitated during a nap. All patients showed moderate restrictive ventilatory defects with reduced maximal buccal pressures and one also showed a low ventilatory response to CO2 rebreathing. Protracted central, obstructive, and mixed apnoeas and hypopnoeas were commonly observed during sleep. There were no changes in heart rate during these events. A combination of respiratory and cardiovascular mechanisms might have been responsible for the severe complications described.

Syringobulbia is an uncommon lesion of the central nervous system. It is defined as a pathological cavitation of the brain stem. The most common symptoms are headache, vertigo, dysphonia or dysarthria, trigeminal paraesthesia, dysphagia, diplopia, tinnitus, palatal palsy. Syringobulbia occurs with atlantoaxial congenital abnormalities (Chiari malformation), infection, tumours, and other causes. The idiopathic syringobulbia is however a rare finding. Early surgical treatment is the treatment of choice. We report on a 58-year old female patient with idiopathic syringobulbia. She complained of occipital headaches and vertigo. On examination she had horizontal nystagmus and diplopia. Occipital headaches and vertigo were improved after operation. We review the literature on syringobulbia, and discuss the clinical features of this uncommon condition.

We report a patient with syringobulbia extending to the pons, who could not open his mouth widely. He had been involved in the traffic accident at 16 years of age. Since them he had suffered numbness in the left neck and arm. At age 30, he became unable to open the mouth widely with pain in the left jaw joint. He also noted dysphagia and tinnitus. Neurologically, there were vocal cord paresis, dysesthesia of the face, ageusia and cerebellar ataxia all on the left side. Brain MRI revealed syringobulbia which extended to the pons. Spinal MRI revealed syringomyelia through the entire spinal cord. The syrinx of the spinal cord seemed to connect with the brainstem lesion. EMG of the masticatory muscles revealed paradoxical activity in the left masticatory muscles. We concluded that disturbance of jaw-opening in this case was caused by syringobulbia, the lesion of which could involve masticatory central pattern generator in the brainstem.

A 36-year-old woman presented with a history of change in voice of 1 month's duration and difficulty swallowing and episodes of nasal regurgitation of 6 days' duration. Examination revealed paralysis of the right vocal fold and the right side of the soft palate. On further investigation, she was found to have syringomyelia with syringobulbia and a Chiari type I malformation. She underwent foramen magnum decompression surgery and was followed up for 1 year. Her dysphagia and nasal regurgitation resolved, but no functional improvement was seen in either her vocal fold or palate.

A 15-month-old girl presented with a spinal pilomyxoid astrocytoma manifesting as a 3-month history of dysphagia. Magnetic resonance imaging showed an intramedullary mass of the cervical spinal cord at C1-C6 with syringobulbia. She underwent partial removal of the tumor and received postoperative chemotherapy with cisplatin and etoposide. The tumor completely responded to the treatment and has not relapsed for 64 months. Pilomyxoid astrocytoma frequently occurs in the opticohypothalamic regions but is rare in the spine. The present case suggests that surgery followed by chemotherapy with cisplatin and etoposide may be an effective therapeutic option for pilomyxoid astrocytoma of the cervical spinal cord.
