BACKGROUND Aggressive fibromatosis is a rare histologically benign but locally infiltrative myofibroblastic tumor. Primary intracranial aggressive fibromatosis (IAF) can exhibit a clinically malignant course. OBSERVATIONS A 22-year-old otherwise healthy woman presented with left painful ophthalmoplegia. Magnetic resonance imaging (MRI) revealed a left sellar tumor with cavernous sinus invasion. Endoscopic transsphenoidal surgery was performed. The lesion could not be totally resected. An inflammatory myofibroblastic tumor was suspected, so steroid pulse therapy was introduced, but it was ineffective. The tumor recurred after a few months, and she complained of visual acuity loss, abducens nerve palsy, trigeminal neuralgia, and panhypopituitarism. The lesion was diagnosed as primary IAF by a pathological review. Gamma Knife radiosurgery was performed, and chemotherapies were introduced but ineffective. Her consciousness was disturbed, and MRI showed hypothalamic invasion of the tumor, occlusion and stenosis of carotid arteries, and cerebral stroke. Palliative care was introduced, and she died 32 months after the onset. The autopsy revealed tumor invasion to the cavernous sinus, optic nerve, hypothalamus, pituitary, and tonsillar herniation due to massive cerebral stroke. LESSONS Radical resection can be impossible in patients with IAF. Radiotherapy and chemotherapy are not always effective for residual lesions. Adjuvant therapy for IAF remains to be explored.

BACKGROUND Extracranial arteriovenous malformations (AVMs) are rare clinical entities and on rare occasions cause neurological symptoms. The authors report a case of an extracranial pterygoid AVM and a subsequent contralateral cavernous sinus dural arteriovenous fistula (dAVF) presenting with abducens nerve palsy. OBSERVATIONS An 80-year-old woman was referred to the authors’ hospital with left abducens nerve palsy followed by right ophthalmalgia. Magnetic resonance imaging (MRI) showed abnormal vessel staining in the left pterygoid and the right inferior petrosal sinus (IPS). Cerebral angiography revealed a left pterygoid AVM draining into the right IPS via the cavernous sinus (CS). A dAVF in the right CS was also revealed. The right ophthalmalgia disappeared spontaneously, and, 4 months later, the left abducens nerve palsy also disappeared after conservative management. Follow-up MRI showed spontaneous regression of the AVM and dAVF. The disappearance of the dAVF was considered to be due to spontaneous regression of the left pterygoid AVM and the consequent decrease in venous pressure of the CS, and the symptoms eventually disappeared. LESSONS The authors treated an extremely rare case of extracranial AVM with dramatic changes in vascular structure and symptoms. Understanding of the pathophysiology between symptoms and dynamic changes in the vascular structure is essential for providing the appropriate treatment.

Object. Nonfunctioning pituitary adenomas comprise approximately 30% of all pituitary tumors. The purpose of this retrospective study is to evaluate the efficacy and role of gamma knife radiosurgery (GKS) in the management of residual or recurrent nonfunctioning pituitary adenomas. Methods. A review was conducted of the data obtained in 42 patients who underwent adjuvant GKS at the University of Pittsburgh between 1987 and 2001. Prior treatments included transsphenoidal resection, craniotomy and resection, or conventional radiotherapy. Endocrinological, ophthalmological, and radiological responses were evaluated. The duration of follow-up review varied from 6 to 102 months (mean 31.2 months). Fifteen patients were observed for more than 40 months. The mean radiation dose to the tumor margin was 16 Gy. Conformal radiosurgery planning was used to restrict the dose to the optic nerve and chiasm. Tumor control after GKS was achieved in 100% of patients with microadenomas and 97% of patients with macroadenomas. Gamma knife radiosurgery was equally effective in controlling adenomas with cavernous sinus invasion and suprasellar extension. No patient developed a new endocrinological deficiency following GKS. One patient's tumor enlarged with an associated decline in visual function. Another patient experienced a deterioration of visual fields despite a decrease in tumor size. Conclusions. Gamma knife radiosurgery can achieve tumor control in virtually all residual or recurrent nonfunctioning pituitary adenomas. Dose sparing facilitates tumor management even when the adenoma is close to the optic apparatus or invades the cavernous sinus.

Object. The authors sought to assess the functional tolerance and tumor control rate of cavernous sinus meningiomas treated by gamma knife radiosurgery (GKS). Methods. Between July 1992 and October 1998, 92 patients harboring benign cavernous sinus meningiomas underwent GKS. The present study is concerned with the first 80 consecutive patients (63 women and 17 men). Gamma knife radiosurgery was performed as an alternative to surgical removal in 50 cases and as an adjuvant to microsurgery in 30 cases. The mean patient age was 49 years (range 6–71 years). The mean tumor volume was 5.8 cm3 (range 0.9–18.6 cm3). On magnetic resonance (MR) imaging the tumor was confined in 66 cases and extensive in 14 cases. The mean prescription dose was 28 Gy (range 12–50 Gy), delivered with an average of eight isocenters (range two–18). The median peripheral isodose was 50% (range 30–70%). Patients were evaluated at 6 months, and at 1, 2, 3, 5, and 7 years after GKS. The median follow-up period was 30.5 months (range 12–79 months). Tumor stabilization after GKS was noted in 51 patients, tumor shrinkage in 25 patients, and enlargement in four patients requiring surgical removal in two cases. The 5-year actuarial progression-free survival was 92.8%. No new oculomotor deficit was observed. Among the 54 patients with oculomotor nerve deficits, 15 improved, eight recovered, and one worsened. Among the 13 patients with trigeminal neuralgia, one worsened (contemporary of tumor growing), five remained unchanged, four improved, and three recovered. In a patient with a remnant surrounding the optic nerve and preoperative low vision (3/10) the decision was to treat the lesion and deliberately sacrifice the residual visual acuity. Only one transient unexpected optic neuropathy has been observed. One case of delayed intracavernous carotid artery occlusion occurred 3 months after GKS, without permanent deficit. Another patient presented with partial complex seizures 18 months after GKS. All cases of tumor growth and neurological deficits observed after GKS occurred before the use of GammaPlan. Since the initiation of systematic use of stereotactic MR imaging and computer-assisted modern dose planning, no more side effects or cases of tumor growth have occurred. Conclusions. Gamma knife radiosurgery was found to be an effective low morbidity—related tool for the treatment of cavernous sinus meningioma. In a significant number of patients, oculomotor functional restoration was observed. The treatment appears to be an alternative to surgical removal of confined enclosed cavernous sinus meningioma and should be proposed as an adjuvant to surgery in case of extensive meningiomas.

Background: The rates of incomplete surgical resection for pituitary macroadenomas with cavernous sinus invasion are high. In growth hormone-producing adenomas, there is a considerable risk for persistent acromegaly. Thus, effective treatment options are needed to limit patient morbidity and mortality. This multicenter study assesses the efficacy and safety of robotic radiosurgery (RRS) for patients with cavernous sinus-invading adenomas with persistent acromegaly. Methods: Patients who underwent RRS with CyberKnife for postoperative acromegaly were eligible. Results: Fifty patients were included. At a median follow-up of 57 months, the local control was 100%. The pretreatment insulin-like growth factor 1 (IGF-1) levels and indexes were 381 ng/mL and 1.49, respectively. The median dose and prescription isodose were 18 Gy and 70%, respectively. Six months after RRS, and at the last follow-up, the IGF-1 levels and indexes were 277 ng/mL and 1.14, as well as 196 ng/mL and 0.83, respectively (p = 0.0001 and p = 0.0002). The IGF-1 index was a predictor for biochemical remission (p = 0.04). Nine patients achieved biochemical remission and 24 patients showed biochemical disease control. Three patients developed a new hypopituitarism. Conclusions: RRS is an effective treatment for this challenging patient population. IGF-1 levels are decreasing after treatment and most patients experience biochemical disease control or remission.

Abstract Background Despite the recent advances in skull base surgery, microsurgical techniques, and neuroimaging, yet surgical resection of clinoidal meningiomas is still a major challenge. In this study, we present our institution experience in the surgical treatment of anterior clinoidal meningiomas highlighting the role of extradural anterior clinoidectomy in improving the visual outcome and the extent of tumor resection. This is a prospective observational study conducted on 33 consecutive patients with clinoidal meningiomas. The surgical approach utilized consisted of extradural anterior clinoidectomy, optic canal deroofing with falciform ligament opening in all patients. The primary outcome assessment was visual improvement and secondary outcomes were extent of tumor resection, recurrence, and postoperative complications. Results The study included 5 males and 28 females with mean age 49.48 ± 11.41 years. Preoperative visual deficit was present in 30 (90.9%) patients. Optic canal involvement was present in 24 (72.7%) patients, ICA encasement was in 16 (48.5%), and cavernous sinus invasion in 8 (24.2%). Vision improved in 21 patients (70%), while 6 patients (20%) had stationary course and 1 patient (3%) suffered postoperative new visual deterioration. Gross total resection was achieved in 24 patients (72.7%). The main factors precluding total removal were cavernous sinus involvement and ICA encasement. Mortality rate was 6.1%; mean follow-up period was 27 ± 13 months. Conclusions In this series, the use of extradural anterior clinoidectomy provided a favorable visual outcome and improved the extent of resection in clinoidal meningioma patients.

AbstractLesions of the oculomotor nerve as the first sign of pituitary adenoma are rare. The cause of such lesions without other clinical symptoms is discussed in this study. A small cohort of 4 patients (3.1%) with oculomotor nerve palsy (third nerve palsy) as the only neurologic deficit, from 129 patients who got operated upon for pituitary adenomas, is presented. In this group (mean age: 55 years, range: 36–65 years), all patients (two women and two men) underwent surgery. In two cases, there was arrested pneumatization and thickened bone. In the remaining two cases, a macroscopically visible, very solid opaque diaphragm was present, after the removal of the tumor and thickened bone. Complete adjustment was observed in all patients within 1 week after the surgery. Two factors that seem to increase the high risk for the development of oculomotor nerve palsy are that the cavernous sinus may be the only weak structure surrounding the sella turcica when the diaphragm and bone are thickened; and the rapid development of increased pressure in this region. The increased pressure on the cavernous sinus during the anatomical variations is the primary cause for lesions on the oculomotor nerve. However, this conjecture cannot be statistically demonstrated because of the small number of cases. Future research should be conducted on larger samples to increase statistical inference and generalizability.

Abstract The so-called cavernous sinus is a venous pathway, an irregular network of veins that is part of the extradural venous network of the base of the skull, not a trabeculated venous channel. This venous pathway, the internal carotid artery, and the oculomotor cranial nerves cross the medial portion of the middle cranial fossa in an extradural space formed on each side of the sella turcica by the diverging aspects of a dural fold. In this space the venous pathway has only neighborhood relations with the internal carotid artery and the cranial nerves. The space itself must be distinguished from the vascular and nervous elements that it contains. The revision of the anatomy of this region has not only theoretical interest but also important clinical implications.
