Arachnoid villi and granulations are thought to represent the primary sites where cerebrospinal fluid (CSF) is absorbed. However, these structures do not appear to exist in the fetus but begin to develop around the time of birth and increase in number with age. With the use of a constant pressure-perfusion system in 2- to 6-day-old lambs, we observed that global CSF transport (0.012 +/- 0.003 m...

DESCRIPTION A 2-year-old boy presented with an atypical craniofacial cleft going through the right nostril with a soft-tissue extension of 2 × 1 cm. A computed tomographic scan showed bony involvement of the right nasal bone, right frontal bone, anterior cribriform plate anomalies, and no encephalocele.

Esthesioneuroblastoma is a rare tumor localized in the superior part of the nasal cavity. Extension in the anterior cerebral fossa is sometimes observed. As we discovered in our patient, the location of the tumor above the cribriform plate was very unusual and meningioma was suspected. Features and prognosis are discussed below.

After a difficult nasal intubation a premature infant leaked cerebrospinal fluid (CSF) from one nostril. After developing bacterial meningitis, the baby was referred for neurosurgical management of the CSF fistula. Transaxial computed tomograms demonstrated a nasal encephalocele, but coronal scans were needed to show the defect in the cribriform plate.

introduction: endoscopic repair is considered the treatment of choice in cerebrospinal fluid (csf) rhinorrhea. the aim of our study was to analyze the etiopathogenesis of csf rhinorrhea, the outcome of treatment and the causes of failure in a developing-country setting.   materials and methods: a retrospective review of patients treated with endoscopic repair for csf rhinorrhea at a tertiary ca...

OBJECTIVE We evaluated the extent of asymmetry evident in paranasal sinus computed tomography (CT) scans of Turkish patients without sinusitis in the ethmoid roof. Our data contribute to the body of knowledge on the subject. MATERIALS AND METHODS We retrospectively studied multiplanar reformatted CT images of the paranasal sinus (1-mm sections) from 110 patients (50 male, 60 female). Ethmoid ...
