“…Meningoencephaloceles are malformations characterized by protrusion of meninges and/or brain tissue due to a skull defect that may be the result of various acquired processes including trauma, surgery, infection, and neoplasm, or of a primitive defect of neural tube closure. [13][14][15] To our knowledge, such a condition has never been previously described in Hunter syndrome; therefore, all the MR imaging examinations were reevaluated to define the frequency of focal parenchymal and/or meningeal herniation in our cohort and the possible correlation with clinical phenotype or other neuroradiologic abnormalities.…”

“…The more common trans-sphenoidal encephalocele can occur through a larger defect in the sellar floor, planum sphenoidale or posterior ethmoid. 5,21) Intrasphenoidal encephalocele may in general be immediately apparent in infants who present with cranial-facial midline defects and endocrine dysfunctions. In contrast, all eight previous cases of intrasphenoidal encephalocele occurred in middle-aged patients presenting with CSF rhinorrhea.…”

“…2) Few cases of intrasphenoidal encephalocele have been reported. 1,4,5) Therefore, diagnosis and treatment is a challenge for the rhinologist and skull base neurosurgeon.

“…5) Sphenoidal encephaloceles can be subdivided on the basis of the defect origin into the median type, arising from the superior or posterior wall of the SS, and the lateral type, arising from the lateral wall of the sinus. 22) This anomaly can extend to the SS (intrasphenoidal encephalocele), and traverse the sinus floor and reach the epipharynx (transsphenoidal encephalocele).…”

Temporosphenoidal encephalocele (TSE) is a rare entity caused by herniation of the anteromedial temporal lobe into the sphenoid sinus (SS) through a middle fossa (MF) defect. A 45-year-old woman presented with a spontaneous TSE manifesting as a 4-year history of recurrent cerebrospinal fluid rhinorrhea and meningitis. Coronal computed tomography showed a skull defect in the superior wall of the right lateral recess of the SS. This homogeneous intrasphenoidal lesion appeared hypointense on T 1 -weighted magnetic resonance (MR) imaging and hyperintense on T 2 -weighted MR imaging. The patient underwent a frontotemporal craniotomy and extradural MF exploration. The encephalocele was amputated and the temporal base dura primarily sutured and reinforced with fat graft. The MF hole was plugged with temporalis fascia and a calvarial graft layered over the bone defect. Histological examination confirmed meningoencephalocele. Rhinorrhea resolved and the patient remained asymptomatic. Resection of an anteromedial TSE and closure of the craniodural defect in the MF floor via a less invasive extradural skull base approach is effective.

One type of congenital intrasphenoidal meningoencephalocele is remnant of lateral craniopharyngeal (Sternberg's) canal. We present a case of a 23-year girl with 10-month history of right side CSF rhinorrhea. CT scan, MRI revealed congenital meningoencephalocele and CSF leak from middle fossa to right side of sphenoid sinus, and there were bony defects at the floor of the anterior aspect of the right middle fossa. Transcranial repair was performed with right side pterional craniotomy. Careful preoperative evaluation and localization of the sphenoid defect are essential for selection of the best possible surgical approach and skull base reconstruction for repair of sphenoid sinus CSF leaks and meningoencephaloceles. In this case, an endoscopic technique was not successful so, transcranial repair was performed with right side pterional craniotomy. KeywOrds: Meningoencephalocele, Rhinorrhea, Transcranial repair ÖZSfenoid kanat içine yerleşmiş meningoensephalosel, lateral kraniofarengial kanalın (Stenberg'in kanalı) artığından meydana gelen bir konjenital anomalidir. Sağ burun deliğinden 10 aydan beri BOS gelen 23 yaşında kadın olgu olarak sunulmuştur. Bilgisayarlı tomografi ve manyetik rezonans görüntülemede; sağ orta fossa tabanının anterior yüzündeki kemik defekti ile sfeneoid sinüsün sağ tarafı arasında ilişki bulunmuştur. Sağ piterional kraniotomi yapılarak; kranial yoldan kemik defekti onarıldı. Sfenoid sinüsden BOS kaçağı olan ve meningoensefeloseli olan hastalarda ameliyat öncesi dönemde detaylı görüntüleme çalışmaları ile defekt ortaya konmalı ve en iyi cerrahi yaklaşım yolu bu görüntüleme çalışmalarına göre belirlenmelidir. Olgumuzda endoskopik girişimin başarısız olması nedeni ile sağ piterional kraniotomi yapılarak defekt onarımı yapılmıştır.
