Meningiomas account for 15% of all intracranial tumors and are the most common extra-axial tumor. J Neurosurg 2011 . Parasellar tumours can affect vital anatomical structures, causing a broad spectrum of manifestations, the type and severity of which depend on size, location, biological behaviour of the tumour and age at diagnosis [1, 8, 9]. Telehealth Services. In sellar and parasellar region, these lesions can originate from the sellar diaphragm, the sellar tuberculum, the anterior clinoid process and the medial portion of the small wings 19. Parasellar meningiomas (m.) may be subdivided in three groups on the basis of their anatomical location and radical removal possibility. AdVAnces in the MAnAgeMent of skull bAse MeningioMA! The parasellar compartments are located lateral to and on either side of the sella turcica. The pituitary gland sits in a bony compartment (called the sella turcica) at the base of the skull and . Abstract. The magnetic resonance imaging showed an enhancing extra-axial dural-based mass in the left parasellar region invading cavernous sinus, hyper-intense on T2 . Meningiomas are one of the most frequent tumors arising from parasellar spaces. The 'true' spheno-cavernous m. are those that grow primarily in the cavernous sinus (c.s. 2.3.4 Meningioma. The cavernous sinuses are the most prominent anatomic feature of the parasella. [QxMD MEDLINE Link]. published in 2015 a series of 15 patients in whom the EED was used to treat meningiomas involving the parasellar region (sella, CS, Meckel's cave, and clivus). The differential diagnosis of lesions in the suprasellar and parasellar regions of the brain includes pituitary adenoma, craniopharyngioma, cystic lesions such as Rathke's cleft cyst, nonpituitary masses, and nontumor causes such as infections and granulomatous disease. Approximately 10% of all intracranial meningiomas involve parasellar structures, and approx 10% of all parasellar tumors are meningiomas. A total of 189 patients (22.2% males, n = 42) form the cohort. In their series, 31 preoperative CN palsies related to the tumor were documented in 12 patients (80%). We usually schedule a follow-up appointment for a week or two after you leave the hospital.

The purpose of this study is to determine the MR imaging features of SFT in the intracranial and extracranial head and neck regions. The majority are situated in the suprasellar region, taking their dural origin from the tubercu-lum sellae, planum sphenoidale, olfactory groove, diaphragma sellae, medial sphenoid wing, optic nerve sheath, and anterior fossa floor/orbital roof. Objective: To study the effect of microsurgery for parasellar menningiomas and to analyze the impact factors of recurrence. Meningiomas in this location tend to invade adjacent suprasellar, cavernous sinus, and petroclival regions, at times involving crucial neurovascular structures (internal carotid artery and branches . After the surgery, 13 CN palsies (42%) improved or resolved, and 18 CN . They frequently compress, encase, or even invade adjacent neurovascular structures of the anterior and middle skull base, thus making their surgical management challenging for skull base surgeons. Meningioma is the most frequent intracranial benign tumor,accounting for 37.1% of tumors overall[1].However,the concomitant occurrence of meningioma and other intracranial benign tumors is extremely rare[2].Only a few coexisting meningioma and other intracranial benign tumor cases have been reported in previous publications,such as pituitary adenoma[3,4],craniopharyngioma[5]and . Parasellar extra-axial cavernomas are rare lesions. During pregnancy, meningiomas may grow more aggressively because of greater hydric . tumor diagnostically from other parasellar masses, in partic ular from meningioma. The rate of misdiagnosis before surgery is high, which results in increased intraoperative bleeding, leading to the impairment of neurological function. Middle Turbinate Preservation in Endoscopic Transsphenoidal Surgery of the Anterior Skull Base 15, 67 - 69 One such challenging location is the parasellar region. In the case of benign nonsymptomatic tumors, observation should be proposed. Involvement of right cavernous sinus and encasement of ipsilateral internal carotid artery are also evident. Progestin intake should be investigated and leads mostly to conservative strategies. Meningiomas were classified according to World Health Organization (WHO) 2007 grading and the location of the tumor was confirmed from the operation records and preoperative imaging. Tumor volume control was achieved in 91.5% (n = 173). Trip.com features the best things to do in Taipei Taiwan, including travel-guide, attractions, restaurants, and cheap hotels. The volumes of the parasellar meningioma were determined on follow-up scans, computed by segmenting the meningioma on a slice-by-slice basis with numerical integration using the trapezoidal rule. Thanks to the introduction of modern diagnostic procedures (cranial computed tomography, CCT; magnetic resonance imaging, MRI; digital subtraction angiography, DSA) careful anesthesiology, and the development of microsurgical techniques with growing experience in the. . These complex clinical aspects make the parasellar tumours challenging even when they have benign histological features. Meningiomas are the second most common sellar/parasellar lesion; in this location, they represent 5 to 11% of all meningiomas. Tumors like chordomas may arise in the sphenoid bone or clivus and affect the sella. Explore 426 research articles published in the Journal Acta Neurochirurgica in the year 2010.
