A 28-year-old male was admitted to our hospital with the complaints of numbness of the left upper limb and gait disturbance. Neurological examination disclosed slight left dysmetria, truncal ataxia and sensory disturbance at the dermatome of C8 and Th1. CT and MRI scans showed a large mass lesion in the left posterior fossa, ventricular dilatation, cavum septi pellucidi and cavum Vergae, empty sella, cervical syringomyelia and left tonsilar herniation. The tumor which attached to cerebellar tentorium was totally removed and a histological diagnosis of meningothelial meningioma was made. Postoperative MRI scan demonstrated a disappearing of syringomyelia with the improved tonsillar herniation. Association of syringomyelia with brain tumor is relatively rare, so its pathogenesis was discussed.

Costello syndrome is a rare but increasingly recognized syndrome of unknown etiology. Neurological abnormalities are not rare in this syndrome and consist of structural and electrophysiological disorders. Ventricular dilatation is observed in more than 40% of cases. Other reported cerebral anomalies are brain atrophy, Chiari malformation and syringomyelia. Although there is insufficient data to propose strict guidelines, it seams reasonnable to have a low threshold for neuroimaging, in general, and particularly when neurologic signs or symptoms are present. Screening including cerebral MRI and EEG should be proposed after a diagnosis of Costello syndrome. The frequency of testing in such children should be guided by neurological follow-up.

A twenty-month-old Chihuahua male dog was presented to us suffering with ataxia. Based on the physical examination, X-ray and magnetic resonance imaging (MRI) examinations, we diagnosed the dog with hydrocephalus, Chiari I malformation and syringomyelia. Treatment consisted of internal medical treatment and the placement of a ventriculoperitoneal (VP) shunt. The ventricular dilatation was relieved and the dog improved neurologically; however, the Chiari I malformation and syringomyelia remained after surgically positioning the VP shunt.

Syringomyelia is often associated with hydrocephalus, especially in Chiari malformations, but it has never been described as a complication of posthemorrhagic hydrocephalus after preterm birth. We report on a premature infant who presented this exceptional association. He was born at 29 weeks of gestational age and suffered a grade 3 intraventricular hemorrhage. Progressive ventricular dilatation developed despite repeated lumbar punctures, and a ventricular reservoir had to be inserted for cerebrospinal fluid drainage. Two weeks later he presented a flaccid, areflexic paralysis of his left upper limb. Magnetic resonance imaging disclosed a remarkable tetraventricular hydrocephalus and a cervical hydrosyringomyelia expanding from the C(5) to T(1) segments. After shunt surgery, the cephalic perimeter stabilized, and the infant began to move his arm. On follow-up, a minimal paresis of the left hand persisted. This case highlights an unreported outcome of posthemorrhagic hydrocephalus. In this context, syringomyelia should be included in the differential diagnosis of any infant with who presents segmental signs of acute or progressive onset.

The occurrence of subdural cerebrospinal fluid collections and ventricular dilatation (external hydrocephalus) after foramen magnum decompression is extremely rare. The authors report on a 37-year-old man who developed symptomatic subdural fluid collections (SFC) after uncomplicated foramen magnum decompression for Chiari I-syringomyelia complex. Postoperative magnetic resonance imaging revealed a supratentorial SFC with prominent midline shift. In addition, bilateral infratentorial SFCs extending supratentorially through the tentorial notch, pseudomeningocele and initial shrinkage of the syrinx were observed. Few days after evacuation of supratentorial collection, the patient experienced increasing headache and a computerized tomography scan demonstrated a contralateral subdural collection as well as ventricular dilatation. A programmable ventriculoperitoneal shunt was placed with resolution of supratentorial collection and progressive improvement of infratentorial collections and pseudomeningocele. Although previous reports described the occurrence of extra-axial fluid collections and hydrocephalus after foramen magnum decompression for Chiari malformation, to our knowledge, this is the only report of acute external hydrocephalus after foramen magnum decompression requiring urgent evacuation of SFC in order to reduce the mass effect.
