Extracranial meningioma has been frequently reported in the sinonasal tract and skull bone, often as extension of intracranial meningiomas. Traditionally,the treatment of these two coexisting tumors required one craniotomy[30,31,33]or two separate operations using two different approaches[2,32,35,39].Prevedello . Introduction: Trigeminal neuralgia (TN) secondary to tumors is encountered in up to 6% of patients with facial pain syndromes and is considered to be associated with tumors affecting the trigeminal nerve pathways. I had radiation almost 9 years ago (30 IMRT treatments). Other tumors like chondrosarcomas, chordomas, and . Petroclival meningiomas are technically challenging lesions regarding the preservation of cranial nerve functioning. Smaller tumors may be treated only with CiberKnife radiation therapy or Proton bean Radiation Therapy. . 1 They are tumors that originate within the suture between the temporal bone and the upper two-thirds of the clivus and remain medial to the fifth cranial nerve. Meningiomas of the midline skull base that arise near the pituitary gland include planum sphenoidale, tuberculum sella, clinoidal, optic canal, cavernous sinus, Meckel's cave and petroclival meningiomas. Treatment was 21 Gy in three fractions. I have a left side pertroclival meningioma wrapped around the carotid artery. Cavernous carotid artery aneurysms: Epidemiology, natural history, diagnostic and treatment. 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, cranial nerves, etc.). Request PDF | Petroclival Meningiomas Diagnosis, Treatment, and Results | The most frequent tumor arising in the petroclival region is meningioma. Treatment was delayed for over a year due to multiple referrals resulting in the development of new symptoms including decreased balance, generalized weakness, and difficulty swallowing. Patient demographics, overall survival, local tumor control rates, and functional outcomes according to multimodal treatments, as well as chronological change in management strategies, were evaluated. They are seated medial to the internal auditory meatus and posterior to the gasserian ganglion. Some patients are not able to undergo surgery. Ninety-two patients with petroclival meningiomas were treated surgically at the authors' institution from 1986 to 2015. Petroclival meningiomas particularly pose a great technical challenge because of their deep location and intimate relation with vital neurovascular structures. Management of petroclival meningiomas includes three options: clinical observation, total removal, and subtotal surgical ablation with or without adjunctive therapy. Clinical observation may be indicated for patients in poor general clinical condition or advanced age. Symptoms typically appear gradually and vary depending on the tumor location. Cancers, an international, peer-reviewed Open Access journal. Rare genetic events in benign meningiomas are mutations in TRAF7, KLF4, AKT1, and SMO; all of these mutations are exclusive of NF2 . Surgical outcomes, however, have improved as neuroimaging and surgical approaches have advanced. Petroclival meningiomas located inferior to the oculomotor nerve and superior or medial to the abducens nerve are ideal for an endoscopic endonasal transclival approach because this prevents the need to work across cranial nerves, limiting operative risk.

At presentation, many patients complain of headaches, gait disturbances and cranial neuropathies. These patients require serial MRI scans for their entire life. The most common recipient tumors are renal cell carcinoma and meningioma, whereas the donor tumors are generally lung and breast carcinomas. In this paper, the authors' aim was to review their series of patients with petroclival meningiomas who underwent surgical treatment; emphasis was placed on evaluating modes of presentation, postoperative neurological outcome, complications, and recurrence rates. Indications for treatment include neurologic deficit from tumor mass effect and documented tumor growth shown on serial imaging studies. Simultaneous treatment of petroclival meningiomas and the trigeminal nerve with gamma knife radiosurgery for tumor-related . conceptually, petroclival meningiomas are located medial to the fifth cranial nerve (cn v). 1 - 4 As lesions arising from the petroclival junction at the upper two thirds of the clivus, PCMs are located medial to the trigeminal nerve. Petroclival meningioma (PCM), closely associated with various cranial nerves and vascular structures, frequently extends into the cavernous sinus or middle cranial fossa, leading to difficulty in exposure during surgery and relatively high surgical morbidity or mortality [1, 2].Even though most PCMs follow a benign clinical course, gross total resection (GTR) is considered the ideal treatment . Petroclival meningiomas are surgically challenging tumors due to the proximity to cranial nerves, major blood vessels, and the brainstem with considerably high postoperative morbidity and mortality. Since the vast majority of meningiomas are benign (noncancerous), they are most commonly treated with surgery. 8, 15, 70, 71 Stereotactic radiosurgery is an important complementary treatment option (both in the frame of AHS and as .

Incidental tumors in elderly patients may be managed with observation with surveillance MRIs. Tumors extended into adjoining regions in 57% of the patients. Methods A task force was created by the EANS skull base section along with its members and other renowned experts in the field to generate recommendations for the management of these tumors. The best chance for cure of a meningioma is gross total resection with . The journal publishes majorly in the area(s): Neuroradiology & Intracranial pressure. Petroclival meningioma (PCM) is undoubtedly one of the most difficult tumors to remove in skull base surgery. In the present series, they were the only topography with major motor impairments.

Introduction Meningiomas account for approximately one-third of all tumors in the central nervous system [1]. For intraoperative neurological protection, the experience of the investigators was as follows: (1) The trigeminal nerve is located below the superior petrosal sinus, thus the cauterization of superior petrosal sinus should be given with more attention. The surgical anatomy associated with petroclival meningiomas and the skull base approaches best suited for their resection are reviewed. Surgery may be recommended in larger tumors, tumors in younger patients, or in tumors with symptoms. It is intersected by cranial nerves IV to XI and by the basilar artery with its branches [ 17 ]. Introduction. This systematic review aimed to examine the role of SRS in treating PM cases. There was no difference with respect to immediate postoperative cranial nerve deficit in patients who had GTR compared with those who had subtotal resection.

Meningiomas are the most frequently occurring intracranial tumors. Petroclival meningiomas are the most challenging tumors because of their neurovascular involvements. [1] In our report, a case with metastasizing pulmonary adanocarcinoma into meningotheliomatious meningioma (WHO Grade I) was presented and its clinicopathological features were briefly discussed. Purpose: Petroclival meningioma (PM) is a challenging neuro oncology case and stereotactic radiosurgery (SRS) is proposed as one treatment option. MRI revealed a right inferior clival meningioma. Sometimes radiation can help reduce the size of a meningioma. Petroclival meningiomas (PCMs) are regarded as one of the most formidable challenges in neurosurgery.
