BACKGROUND
Congenital cranial bone defects predispose to herniation of meninges, sometimes with brain tissue involvement, to form a cerebrospinal fluid (CSF)-filled cyst in the head. Such defects mainly results from focal failure of neural tube closure during fetal development and has been reported in various species of domestic mammals.
CASE PRESENTATION
A one week old Ayrshire calf with a fluctuant swelling on parieto-occipital region of the head was referred to the faculty. The calf was always lying on lateral recumbency and exhibited resistance to deep palpation around the swelling and neck flexion. Embedded to the midline of the dorso-caudal surface of the cyst's wall was a hard longitudinally oriented structure. The case was diagnosed as meningocele by means of radiographic examination. As the likelihood to full recovery was greatly reduced due to the negative impact already meted on brain tissue by intracranial pressure, the calf was euthanized on grounds of animal welfare and the diagnosis confirmed by anatomopathological findings which also revealed a circular bone defect in parieto-occipital region of the skull vault and a flattened bony structure embedded to the cyst's wall.
CONCLUSION
Anatomopathological findings confirmed the diagnosis as cranial bifidum with meningocele at the parieto-occipital region of the skull vault. The presence of a bony structure embedded to the wall of meningeal sac was rather unusual and could not be sufficiently explained. It was however thought to, most likely, represent a part of interparietal bone that failed to get incorporated into squamous part of occipital bone as a result of the defect. The report also highlights challenges that work against timely delivery of urgent veterinary interventions in rural set ups of Africa and rest of the developing world, often leaving veterinarians with animal welfare consideration as main determinant of intervention measures.

A case of occult intrasacral meningocele in a 22-year-old female is reported. The clinical and radiological features of this condition are discussed. Its relationship to other cystic sacral conditions is considered. The pathogenesis of this lesion is not perfectly clear.

The first documented description of an anterior sacral meningocele was Bryant's in 1823. Anterior sacral meningocele patients have constipation as a universal symptom; urinary incontinence is also common. All the symptoms are directly related to the pressure from a pelvic mass on adjacent structures. When the patient stands, a headache often develops because the spinal fluid pressure decreases as the meningocele sac fills. Finally, a scimitar-shaped sacrum on a neuroradiological anteroposterior plain assessment is pathognomonic. The coccyx may be absent, and the lower sacral laminae may be absent or incomplete. The surgical options for this rare clinical condition are still matter of debate.Anterior sacral meningocele is a pathology that lacks a current classification and neurosurgical therapeutic standards, even though a similar dynamic has been shown by the related traumatic pseudomeningocele. Anterior approaches (retro- and transperitoneal meningocele neck occlusion with internal cerebrospinal fluid (CSF) cyst drainage) and posterior approaches (posterior sacral laminectomy, dural sac ligation, and CSF cyst drainage) are the available surgical strategies.We now report the case of an adult patient for whom a posterior approach was suggested and performed and report her postoperative surgical follow-up. The surgical rationale is also discussed.

Dermoid sinuses and meningoceles are seldom encountered in the cervical region. Besides, to the best of our knowledge, the coexistence of these types of congenital abnormalities with recurrent meningitis, as well as with mirror movement, has never been reported before. A 14-year-old female with the diagnosis of recurrent meningitis was referred to our clinic from the Department of Infectious Diseases. She had a cervical meningocele mass that was leaking cerebro-spinal fluid (CSF) and an associated mirror movement symptom. Spina bifida, dermoid sinus and meningocele lesions were demonstrated at the C2 level on computed tomography (CT) and magnetic resonance imaging (MRI). She underwent an operation to remove the sinus tract together with the sac, and at the same time the tethered cord between the sac base and the distal end of the spinal cord was detached. The diagnosis of dermoid sinus and meningocele was confirmed histopathologically. These kinds of congenital pathologies in the cervical region may also predispose the patient to other diseases or symptoms. Herein, a case of meningocele associated with cervical dermoid sinus tract which presented with recurrent meningitis and a rare manifestation of mirror movement is discussed. Neurosurgeons should consider the possible coexistence of mirror movement and recurrent meningitis in the treatment of these types of congenital abnormalities.

The most common etiology of classic trigeminal neuralgia is vascular compression. However, other causes must be excluded. It is very unlikely that a meningocele presents with symptomatic trigeminal neuralgia. We present a rare case of a patient presenting with left trigeminal neuralgia. Thin-slice CT and MRI showed a transclival Meckel's cave meningocele. The patient underwent endoscopic repair of the meningocele, which resulted in complete resolution of her symptoms. Meckel's cave meningocele or encephalocele should be considered among the differential diagnoses of trigeminal neuralgia. Meningocele repair should be suggested as the first treatment option in this rare situation.

Otology & Neurotology : Official... Jun 2009The purpose of this study is to report 2 rare cases of congenital fallopian canal meningoceles.
OBJECTIVE
The purpose of this study is to report 2 rare cases of congenital fallopian canal meningoceles.
INTERVENTIONS
Magnetic resonance imaging, computed tomography (CT) of the temporal bone, CT-cisternogram, and combined transmastoid approach with middle fossa craniotomy in 2 patients.
MAIN OUTCOME MEASURES
Radiologic and operative diagnosis of congenital fallopian canal meningoceles.
RESULTS
Presentations included spontaneous cerebrospinal fluid (CSF) otorrhea and recurrent meningitis with intracranial hypertension. Postoperative complications included facial nerve palsy and persistent CSF leaks that necessitated ventriculoperitoneal shunt and lumbar drain placement.
CONCLUSION
Use of CT of the temporal bone in combination with CT-cisternogram may define sites of active CSF leak. Intraoperative use of fluorescein may assist identification of cranial base defects to lower rates of recurrence, and intraoperative use of cranial nerve monitoring can minimize the risk of nerve injury during repair.

Here we report an anterior thoracic meningocele case. Twoyears- old female patient was presented with kyphosis. Azygos lobe of the lung was also demonstrated during radiological studies. Posterolateral thoracotomy incision and extralpeural approach was performed for excision of the anterior meningocele to untether the cord. Although both anomalies are related to faulty embryogenesis and it is well known that faulty embryogenesis may also reveal coexisting abnormalities, we could not speculate a common mechanism for anterior thoracic meningocele and azygos lobe of the lung association.

Review
In this article the Authors describe a case of intrathoracic meningocele. That was diagnosed in a young asymptomatic woman after surgical resection. After a complete and accurate review of the literature, the Authors underline the rarity of the find while they also note the association of this pathology with Von Recklinghausen's neurofibromatosis. They also discuss etiology and clinical diagnostic aspects as well. In conclusion the Authors insist that with new diagnostic imaging techniques available today it is possible to accurately diagnose this disease preoperatively in most patients. This fact along with improved therapeutic regimens makes surgical excision almost free from the complications that were at one time observed.
