Cerebellar dermoid tumor and occipital meningocele in a monozygotic twin: clues to the embryogenesis of craniospinal dysraphism.

A case of monochorionic/monoamnionic twin with discordant occipital developmental malformations is presented. One female twin appeared to have an occipital meningocele with cerebellar aplasia and died immediately after birth. The other twin presented with signs and symptoms of raised intracranial pressure at the age of 7 months. Severe hydrocephalus was present due to an infected intracerebellar dermoid tumor with a contiguous occipital dermal sinus. The clinical and pathological characteristics are described and the different theories concerning twinning, embryogenesis, and dysmorphology in relation to neural tube defects are discussed. Analysis of the features of these monozygotic twins indicates that a meningocele is not a post-neurulation disorder but results from deficient neurulation, probably due to mesodermal insufficiency.

Surgically verified case of optic sheath nerve meningocele: case report with review of the literature.

Optic sheath meningocele is rare; only approximately 31 cases have been reported. The term optic sheath meningocele has recently been proposed by Garrity and Forbes to describe primary CSF cysts of the optic nerve sheath, without apical mass or malformation of the cranio-orbital junction. Presenting symptoms are often related to involvement of the optic nerve, with a slow or rapid decrease of visual acuity. CT and MRI studies reveal a tubular-cystic enlargement of the optic nerve/optic sheath complex (on/onsc), with thickening of the optic nerve. Radiological differential diagnosis should include optic nerve tumors such as gliomas, meningiomas, and arachnoid cysts involving the optic nerve sheath. Up to now, it seems that early surgical management by means of optic nerve/optic nerve sheath decompression affords an improvement of visual function with minimal morbidity in patients who present a rapid decrease of visual acuity within 3-6 months. We present an additional case and discuss the clinical, radiological, and operative features of this pathological condition of the optic nerve sheath.

Anterior-sacral meningocele; value of magnetic resonance imaging and abdominal sonography. A case report.

With the presentation of a case of giant anterior sacral meningocele, the evident superiority of magnetic resonance imaging over any other methods for the diagnosis of this rare condition is demonstrated. Ultrasound as a screening tool is often the first to reveal the presence of the intrabdominal cystic abnormality and furthermore is an excellent means for checking the post-operative course. In addition this particular case is interesting because the dural stalk linking the meningocele to the dural abdominal sac was not entirely free from nervous structures inspite of macroscopic appearances to the contrary.

Anterior sacral meningocele: report of five cases and review of the literature.

Five new cases of anterior sacral meningocele are presented, including one secondary to neurofibromatosis, a previously undescribed association. The literature is reviewed, drawing attention to the relationship between anterior sacral meningocele, sacral dysgenesis, and other congenital anomalies. Special consideration is given to the clinical features of this entity, as well as to the techniques and results of surgical management.

Giant anterior sacral meningocele and posterior sagittal approach.

OBJECT: Anterior sacral meningocele (ASM) is a rare congenital malformation. Often while still asymptomatic, ASM may achieve a considerably size, to the extent of exerting a mass effect on the pelvic structures. Spontaneous rupture with subsequent septic meningitis is the most frequent and dangerous complication. The meningocelic sac is usually isolated by a surgical procedure that requires a sacral laminectomy or a transabdominal approach. Recently an alternative surgical technique, the posterior sagittal approach, has been proposed. METHODS: We report on a 15-year-old girl with a long clinical history of constipation and sporadic cystitis. Radiological examinations showed progressive enlargement of a presacral lipomeningocele, which grew to 12x14 cm. A posterior sagittal approach was performed; the stalk was ligated, the sac totally excised and a small associated tumour removed. No intra-/post-operative complications were observed. CONCLUSION: The posterior sagittal approach is an easy and safe surgical technique for the treatment of ASM, as it allows a complete isolation of the lesion and the removal of associated tumors without significant morbidity.

Cervical meningocele in association with spinal abnormalities.

CASE REPORT: This case report presents a newborn baby girl, who was diagnosed at birth with a mid-cervical meningocele. Further radiographic workup by MRI revealed co-existing thoracic diplomyelia and bilateral tethered cords. At birth the patient was found to be neurologically intact. Surgery was performed at 4 months of age, the patient undergoing simultaneous repair of the cervical meningocele, exploration of the diplomyelia, and release of the tethered cords bilaterally. Long-term follow-up revealed an ambulating patient with no bowel or bladder incontinence, who has developed well for her chronological age so far. REVIEW OF THE LITERATURE: A review of the literature relevant to this case is also presented.

A case of occult intrasacral meningocele presented with atypical bowel symptoms.

CASE REPORT: We report a case of an occult intrasacral meningocele. An 11-year-old boy presented with atypical bowel symptoms, severe constipation, and stool incontinence. Magnetic resonance (MR) imaging disclosed an intrasacral cyst containing cerebrospinal fluid (CSF). We diagnosed an occult intrasacral meningocele and performed perforation of the cyst and closure of the fistula. The patient was free from constipation and stool incontinence after the operation. DISCUSSION: We discuss the clinical features and neuroradiological findings of this rare condition.

Presacral mass consisting of a meningocele and a Tarlov cyst: successful surgical treatment based on pathogenic hypothesis.

This illustrative case shows a meningocele created by erosion of the sacrum by a perineurial cyst. It is the first report of a large presacral mass consisting of a perineurial cyst and a meningocele simultaneously. We describe a hypothesis for the pathogenesis of this particular constellation of circumstances and present a successful surgical option based on the assumed pathogenesis.

Anaerobic meningitis secondary to a rectothecal fistula arising from an anterior sacral meningocele: report of a case and review of the literature.

An anterior sacral meningocele is a diverticulum of the thecal sac protruding anteriorly from the sacral spinal canal into the extraperitoneal presacral space. It is a rare congenital anomaly comprising of a thin wall of fibrous connective tissue, and containing cerebrospinal fluid and, occasionally, adjacent nerve fibers. We report an unusual case of a 48-year-old male who presented with meningitis secondary to a rectothecal fistula arising from an anterior sacral meningocele.

Anterior sacral meningocele. Current diagnosis.

One hundred fifty cases of anterior sacral meningocele have been reported in the world literature. This rare pathologic entity was first recognized and described by Bryant in 1837. We report a patient with an incidental anterior sacral meningocele. Our patient is the oldest reported in the literature. The incidental feature of this malformation is uncommon. We review the literature and discuss the clinical aspect, diagnosis, and treatment. Emphasis is placed on the current and optimal method of radiologic evaluation using computed tomography scan combined with metrizamide myelography.

Dermoid cyst within an upper thoracic meningocele.

A case of dermoid cyst within an upper thoracic meningocele is reported. The incidental feature of this combination is extremely rare. As upper thoracic meningocele is often associated with other spinal and intracranial abnormalities, close observation and radiologic evaluation of the craniospinal axis are necessary to obtain an exact diagnosis and to achieve an appropriate treatment.

Anterior sacral meningocele presenting as abdominal mass.

Anterior sacral meningocele is a rare entity. It arises from a congenital defect of the sacrum and the coccyx through which herniation of the caudal portion of the meninges and their contents occurs, forming a cyst-like structure. The cystic mass, which lies between the rectum and sacrum, produces a variety of symptoms depending on its size and contents and constitutes a diagnostic problem. A case of anterior sacral meningocele is presented, including the physical signs, differential diagnosis, and the dangers of aspiration or surgical intervention.

Anterolateral lumbar meningocele presenting as an ovarian cyst, in a patient with neurofibromatosis.

A case of an anterolateral lumbar meningocele in a patient with neurofibromatosis is presented. As anterolateral lumbar meningocele may present itself only by non-specific symptoms like low back pain or abdominal pain, such symptoms require prompt diagnostic work up in patients with neurofibromatosis. The significance of MR imaging in early recognition of this rare anomaly is emphasized.

Resection of a giant anterior sacral meningocele via an anterior approach: case report and review of literature.

BACKGROUND: An anterior sacral meningocele is a rare form of spinal dysraphism that is sometimes associated with syndromes such as Currarino and Marfan syndromes. These lesions rarely cause neurological complications, but meningitis, sepsis, obstetric problems, and bowel and bladder difficulties are common secondary conditions. The lesions can even be fatal. Because these lesions usually do not regress spontaneously, surgical treatment is the standard for symptomatic or growing masses. The dural defect can be repaired with a variety of anterior or posterior approaches. CASE DESCRIPTION: We present a case of a 16-year-old female patient with a giant nonsyndromic anterior sacral meningocele that we successfully treated using an open anterior approach. We discuss the treatment options and present a brief review of the literature. CONCLUSIONS: Although the posterior approach remains the treatment of choice for most lesions, we believe that the anterior laparotomy provides excellent exposure and is a safe alternative approach for the treatment of selected lesions. Patients with these lesions should be cared for by a multidisciplinary team.

Dermoid tumours occurring at the site of previous meningocele repair.

Two cases of dermoid tumours following meningocele repair have been reported because of the rarity of the condition and paucity of literature. It should be stressed that a dermoid tumour should be considered in the differential diagnosis of neurological deterioration in patients with a repaired meningocele.
