Abstract We report the case of a young girl who suffered bilateral upper extremity paralysis after minor head trauma. Her clinical picture, as well as radiographic evidence of a fracture at C1, led to the diagnosis of Bell's cruciate paralysis, caused by a small lesion in the rostral part of the pyramidal decussation. Magnetic resonance images showed, in addition to a Chiari Type I malformation, an abnormality in the medulla. All previous cases of cruciate paralysis lack both pathological and radiographic supporting evidence.

Objective. The aim of this study was to determine the posterior cranial fossa volume, cerebellar volume, and herniated tonsillar volume in patients with chiari type I malformation and control subjects using stereological methods.Material and Methods. These volumes were estimated retrospectively using the Cavalieri principle as a point-counting technique. We used magnetic resonance images taken from 25 control subjects and 30 patients with chiari type I malformation.Results. The posterior cranial fossa volume in patients with chiari type I malformation was significantly smaller than the volume in the control subjects (P<0.05). In the chiari type I malformation group, the cerebellar volume was smaller than the control group, but this difference was not statistically significant (P>0.05). In the chiari type I malformation group, the ratio of cerebellar volume to posterior cranial fossa volume was higher than in the control group. We also found a positive correlation between the posterior cranial fossa volume and cerebellar volume for each of the groups (r=0.865,P<0.001). The mean (±SD) herniated tonsillar volume and length were0.89±0.50 cm3and9.63±3.37 mm in the chiari type I malformation group, respectively.Conclusion. This study has shown that posterior cranial fossa and cerebellum volumes can be measured by stereological methods, and the ratio of these measurements can contribute to the evaluation of chiari type I malformation cases.

Abstract Introduction Chiari type I malformations can present in different ways, but the most frequent symptom is an occipitocervical headache. Hearing loss as the main presenting symptom is rare. Case A young woman with progressive left-sided unilateral hearing loss was diagnosed with a Chiari type I malformation. She underwent a suboccipital craniectomy with C1 laminectomy and duraplasty. The hearing loss had resolved postoperatively with normalization of the audiometry. Conclusion Chiari type I malformation can present solely with hearing loss. Improvement after surgical decompression is possible. This phenomenon is not emphasized well enough within the neurologic community. In this report, we present a summary of the pathophysiology and management in Chiari type I malformations.

Chiari Malformations

The association of neurofibromatosis type 1 (NF1) with Chiari malformations of the cerebellum and brain stem has been reported on only two previous occasions.1,2 The pathogenesis of both conditions has remained unclear, although the Chiari type I malformation is most likely due to hypoplasia of the posterior fossa with subsequent extension of the cerebellum through the foramen magnum.3 NF1 is also associated with a variety of cerebral dysplasias.4 We present a patient with both of these dysplastic lesions whose Chiari malformation was asymptomatic.
