Arnold-Chiari malformations (ACM) is a rare congenital hindbrain maldevelopment, leading to downward herniation of the cerebellar tonsils. Clinical features relates to cerebrospinal fluid disturbances, manifesting as symptoms of headaches, pseudotumour-like episodes, cranial nerve palsies and cerebellar dysfunction. Ocular manifestations includes varying ophthalmoloplegia and accommodation abnormalities. Papilloedema has been rarely implicated and remains an uncommon feature of ACM. We report a case of ACM who developed papilloedema and visual disturbance, that was successfully treated with suboccipital decompression. The presentation of patients with ACM-I and papilloedema unaccompanied by localising signs may resemble that of IIH. Neuroimaging with special attention to the craniocervical junction in saggital and transverse planes is crucial. Surgical decompression of the posterior fossa seems to improve headache symptoms and clinical signs of papilloedema.

Suboccipital Decompression

✓ Chiari I malformation, a congenital disorder involving downward displacement of the cerebellar tonsils through the foramen magnum, is often treated surgically by performing suboccipital craniectomy and C-1 laminectomy. The authors report two cases in which fracture of the anterior atlantal arch occurred during the postoperative period following Chiari I decompression and C-1 laminectomy causing significant neck pain. The findings indicate that interruption of the integrity of the posterior arch of C-1, iatrogenically or otherwise, confers increased risk of anterior arch fracture. A C-1 fracture should therefore be considered in the differential diagnosis of posterior cervical pain in patients who have previously undergone decompression for Chiari I malformation.

Central Lesions

ABSTRACT OBJECTIVE Trigeminal neuralgia (TN) is usually associated with vascular compression of the trigeminal nerve, but some cases are associated with central lesions such as tumors, aneurysms, or arteriovenous malformations. In this article, we report the 19th case of TN associated with Chiari I malformation and review clinical outcomes and pathophysiology. CLINICAL PRESENTATION A 63-year-old right-handed man initially presented in 1993 with left-sided lancinating facial pain in the V2 distribution of the trigeminal nerve; the pain was triggered by certain movements, tactile stimulation, or a hot shower. Magnetic resonance imaging revealed a Chiari I malformation associated with a syrinx from C1 to C3. INTERVENTION The patient underwent uncomplicated suboccipital craniectomy, C1 laminectomy, and duraplasty for Chiari decompression. Postoperatively, his pain resolved over a period of 1 year. CONCLUSION Chiari I malformation has been found to be associated with TN in 19 cases in the English-language literature. In patients refractory to medical treatment, suboccipital decompression leads to resolution of pain in about two-thirds of patients. Potential mechanisms for the pathogenesis of TN in the setting of Chiari I malformation are discussed. Chiari I malformation is important to consider as a rare cause of TN that responds to surgical therapy.
