Bilateral jugular foramen stenosis with jugular bulb and vein aplasia is rare in nonsyndromic craniosynostosis and usually diagnosed during childhood. We present a case of bilateral jugular foramen stenosis with jugular bulb and vein aplasia, with subsequent persistence and enlargement of the fetal venous anastomosis in the middle and posterior cranial fossa, along with a review of the literature about this anatomical abnormality, highlighting the surgical challenges and management from the otologist/neurotologist point of view.

We present a case of solitary vascular tumor on posterior cranial fossa in a 15-year-old female who had a complaint of headache on/off for six months with associated dizziness, nausea, vomiting and vertigo. Well circumscribed solid vascular mass was localized on posterior fossa by computed tomography along with magnetic resonance imaging scan. Furthermore, the diagnosis was confirmed by surgical findings and histological examinations.Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page: 47-50

Abstract A rare case of a meningioma of the posterior margin of the petrous temporal bone associated with cerebrospinal fluid rhinorrhea is presented. After a careful review of the literature, the possible pathogenesis of the fistulous tract is discussed. (Neurosurgery 21:742-744, 1987)

Abstract Background The enlargement of the posterior cranial fossa volume is considered one of the main steps of the surgical management of children with multiple sutures craniosynostosis. Different management options have been proposed including fixed expansive craniotomy, free bone flap craniotomy, and distraction osteogenesis. Objectives To review indications to “free bone flap” craniotomy for the posterior fossa expansion, detailing advantages, disadvantages, and complications related to the technique. Results and conclusions A review of the literature shows that “free bone flap” posterior expansion cranioplasty still has a role, particularly in infants with thin and “honeycomb” structure of the bone, allowing to gain adequate intracranial volume increases and to postpone to a more adequate time surgery aimed at anterior cranial fossa expansion.

Two hundred and forty-five temporal bone specimens were examined radiographically. Subsequently the topographic relationship between the jugular fossa and surrounding structures was evaluated in plastic casts of the specimens. Fifty-eight casts showed a high jugular fossa and in 17 a jugular bulb diverticulum was found. A diverticulum is regarded as an anomaly of the high jugular bulb and presumably has a potential for expansion. Most frequently a diverticulum was directed medially into the space between the internal acoustic meatus, the vestibular aqueduct and the posterior cranial fossa. Seven diverticula reached the level of the internal acoustic meatus. Encroachment upon the vestibular aqueduct was seen in 4 casts and both the internal acoustic meatus and the cochlear aqueduct were very close to the diverticulum. A few diverticula were directed postero-laterally close to the facial canal and the stapedius muscle. The investigation was supplemented with a selected clinical material of radiographs of temporal bones with high fossae. The results corresponded to those of the experimental investigation. The jugular bulb diverticulum is a relatively common feature and should be regarded as an anomaly with a potential to give rise to clinical symptoms consequent to its intrusion upon surrounding structures.

Jugular foramen is a hiatus in the posterior cranial fossa that transmits the internal jugular vein among other structures. The knowledge of the jugular foramen is important in neurosurgical procedures. The objective of the study was to characterize the morphology and the dimensions of jugular foramen in dry Nigerian skulls. One hundred and seventy jugular foramens from 85 dry adult skulls of unknown sex were studied. Morphology was studied by observation and measurements were taken with Venier caliper. The parameters that were studied included the shape, septation, medio-lateral diameter, antero-posterior diameter of jugular foramen, and the dome, width and depth of jugular fossa. Oval shaped foramen (77%) was more prevalent than round shaped foramen (23%). Complete septation was found in 19.4% of skulls, while incomplete septation was found in 41.2% of skulls. Absence of septation was found in 39,4% of skulls. Dome over the jugular fossa was present in 67,6% and absent in 32,4% of the skulls. The antero-posterior diameter (right - 13,20mm±2.8, left - 11,72±2.8) and medio-lateral diameter (right – 18.73mm±3.5, left – 17,33mm±3.1) were significantly higher on the right side than on the left side. The depth of jugular fossa was significantly higher on the right side (12.38mm±2.4) than on the left side (10.95mm±2.8). The width of jugular fossa was higher on the right (12.06mm±3.6) than on the left (11.80mm±3.3) but the difference was not significant. The present study demonstrated right sided dominance in the metric parameters of the jugular foramen in our environment. El foramen yugular es un hiato en la fosa craneal posterior que transmite la vena yugular interna entre otras estructuras. El conocimiento del foramen yugular es importante en procedimientos neuro-quirúrgicos. El objetivo del estudio era caracterizar la morfología y las dimensiones del foramen yugular en cráneos nige-rianos secos. Cientos y setenta forámenes yugulares a partir de 85 cráneos secos del adulto de sexo desconocido fueron estudiados. La morfología fue estudiada por la observación y las medidas fueron tomadas con el calibrador de Vernier. Los parámetros que fueron estudiados incluyeron la forma, la tabicación, el diámetro medio-lateral, el diámetro anteroposterior del foramen yugular, y la bóveda, la anchura y la profundidad de la fosa yugular. El agujero de forma oval (el 77%) era más frecuente que el agujero de forma redonda (23%). La tabicación completa fue encontrada en 19,4% de cráneos, mientras que la tabicación incompleta fue encontrada en 41,2% de cráneos. La ausencia de tabicación fue encontrada en 39,4% de cráneos. La bóveda sobre la fosa yugular estaba presente en 67,6% y ausente en 32,4% de los cráneos. El diámetro anteroposterior (derecho: 13,20 mm±2,8, izquierdo: 11,72±2,8) y el diámetro medio-lateral (derecho: 18,73mm ±3,5, izquierdo: 17,33mm±3,1) eran perceptiblemente más altos en el derecho que en el lado izquierdo. La profundidad de la fosa yugular era perceptiblemente más alta en el derecho (12,38mm±2,4) que en el lado izquierdo (10,95mm±2,8). La anchura de la fosa yugular era más alta en la derecha (12,06mm±3,6) que a la izquierda (11,80mm±3,3) pero la diferencia no era significativa. El actual estudio demostró la dominación del lado derecho en los parámetros métricos del foramen yugular en nuestro medio.
