Clinical Features, Intradural Transcavernous Surgical Management, and Outcomes of Giant Cavernous Sinus Hemangiomas: A Single-Institution Experience

Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. Stereotactic radiosurgery is an effective treatment for small CSHs. The optimal treatment for giant CSHs is controversial. This study reports advantages of a complete intradural transcavernous approach in total resection of CSHs. Between January 2012 and January 2017, 15 patients with giant CSHs were treated surgically. All cases were evaluated with a contrast-enhanced magnetic resonance imaging scan and confirmed histopathologically. A complete intradural approach was used for all patients. Clinical manifestations, radiographic characteristics, operative techniques, and outcomes of patients were analyzed. Headache was the most common initial symptom, followed by decreased visual acuity and diplopia. Postoperative magnetic resonance imaging showed that gross total resection was achieved in 13 patients. Two patients had experienced total ipsilateral visual loss for several years before surgery; vision improved in all remaining patients with preoperative visual diminution. The most common early neurologic deficit was cranial nerve VI dysfunction, which was observed in 9 patients (60%; 5 new deficits). Only 2 patients (13.3%) experienced permanent morbidity on long-term follow-up. The early postoperative morbidity rate for cranial nerve III dysfunction was 33.3% (5 patients), and only 1 patient (6.7%) experienced permanent morbidity. Four patients (26.7%) had slight postoperative facial numbness. Surgical total resection is the primary and reasonable choice for giant CSHs. Microsurgical resection of giant CSHs through a completely intradural transcavernous approach is an alternative treatment option for giant CSHs.

Treatment of Cavernous Sinus Hemangiomas with Gamma Knife Radiosurgery as a Primary and Sole Therapy.

To evaluate the effectiveness of Gamma Knife radiosurgery (GKRS) as the primary and only therapy for the treatment of cavernous sinus hemangiomas (CSH) and to report the tumor volume dynamics, course of symptoms, and complications after stereotactic radiosurgery. A total of 10 CSH patients were treated with GKRS using a median margin dose of 14.2Gy (range 13-16Gy). The median follow-up period was 42 months (range 12-85 months). Tumor volumes were calculated from magnetic resonance images before treatment and compared with those after treatment. Prior to the treatment, all patients complained of headache and retro-orbital pain, and six patients complained of diplopia due to abducens nerve paralysis. Within six months of treatment, all patients declared some improvement in headache and retro-orbital pain, and abducens nerve paralysis recovered fully in all six patients. At the first-year follow-up, at least 74% decrease in tumor volume was noted with average tumor volume reduction of 90.2% in all treated patients. Tumors less than 6 cm3 in volume nearly disappeared at 24 months. No tumor progression, re-growth, or radiation-induced adverse effects were noted in our patients. Characteristic radiological features that enable identification of CSH avert the need for an open biopsy for diagnosis. Under suitable circumstances, GKRS may be considered as the primary and only therapy for CSH. GKRS has favorable outcomes in the treatment of CSH, demonstrating good tumor shrinkage, symptom recovery, and low incidence of side effects.

Surgical Management and Outcomes of Cavernous Sinus Hemangiomas: A Single-Institution Series of 47 Patients

The purpose of this study was to analyze the outcomes of cavernous sinus hemangiomas (CSHs) treated surgically, and to investigate factors that affect the gross total resection (GTR), newly developed or deteriorated cranial nerve injury (NDDCNI), and follow-up neurologic performance, and to further discuss the optimal treatment for CSHs. Clinical data of 47 patients with CSHs treated surgically at our institution between 2012-2018 were retrospectively reviewed. GTR was achieved in 26 (55.3%) patients. Significant relations were identified between the invasion of the sella turcica (odds ratio [OR]= 0.012; 95% confidence interval [CI], 0.001-0.213; P= 0.002), skull base ward (OR= 27.838; 95% CI, 2.995-258.748; P= 0.003), and GTR. The preoperative Karnofsky Performance Scale (KPS) score (OR= 2.966, per 10 score increase; 95% CI, 1.136-7.743; P= 0.026) and the invasion of the sella turcica (OR=7.137; 95% CI, 1.282-39.726; P= 0.025) were factors that significantly affected the incidence of NDDCNI. The average follow-up KPS score, which increased significantly compared with the pre (P < 0.001) and postoperative KPS scores (P < 0.001), was 89.1. Increased tumor size (OR= 0.044, per 1cm increase; 95% CI, 0.004-0.477; P= 0.010) was a risk factor for unfavorable follow-up KPS score. Being treated by an experienced skull base surgeon favors the total removal of CSHs, whereas the invasion of the sella turcica does just the opposite. Increased tumor size is a risk factor for unfavorable follow-up KPS score. The invasion of the sella turcica was related to NDDCNI and unfavorable follow-up KPS score.

Gamma Knife radiosurgery for the treatment of cavernous sinus hemangiomas.

The present retrospective study aimed to analyze the outcome of patients with cavernous sinus hemangioma (CSH) treated with Gamma Knife radiosurgery (GKS). Between August 2011 and April 2014, 7 patients with CSHs underwent GKS. GKS was performed as the sole treatment option in 5 patients, whilst partial resection had been performed previously in 1 patient and biopsy had been performed in 1 patient. The mean volume of the tumors at the time of GKS was 12.5±10.2 cm3 (range, 5.3-33.2 cm3), and the median prescription of peripheral dose was 14.0 Gy (range, 10.0-15.0 Gy). The mean follow-up period was 20 months (range, 6-40 months). At the last follow-up, the lesion volume had decreased in all patients, and all cranial neuropathies observed prior to GKS had improved. There were no radiation-induced neuropathies or complications during the follow-up period. GKS appears to be an effective and safe treatment modality for the management of CSHs.

Radiosurgical considerations for cavernous sinus hemangioma: long-term clinical outcomes.

Cavernous hemangiomas are rare vascular tumors in the cavernous sinus. Cranial neuropathies induced by cavernous sinus hemangiomas (CSH) necessitate tumor reduction, but surgery is extremely difficult due to the abundant vascularization of the lesion. We studied the effectiveness and safety of Gamma Knife radiosurgery (GKRS) for CSH. We performed a retrospective analysis of 25 patients with CSH who were treated by GKRS between March 1992 and December 2014. Age, sex, target volume, and irradiation dose were analyzed as prognostic factors for CSH treated by GKRS. Eleven (84.6%) patients had tumor shrinkage within 12months after GKRS. Two patients experienced tumor progression, but tumor size decreased over 2years after GKRS. No patients had permanent complications, and all patients experienced symptomatic improvement. There were no significant factors that predicted the prognosis of CSH. The optimal treatment for CSH has been unclear; however, in this study, GKRS was an effective and safe treatment for CSH. Thus, GKRS may be a primary treatment for CSHs in high-risk surgery patients.

Treatment Strategies of Large and Giant Cavernous Sinus Hemangiomas: Surgery or Radiosurgery?

Background: Cavernous sinus hemangiomas (CSHs) are rare vascular tumors within the cavernous sinus. Radiosurgery is less effective for large and giant CSH than for smaller ones. Objective: To present our surgically treated 26 cases of large and giant CSHs, the largest single-institution series reported thus far, and further conduct a systematic review and meta-analysis of the treatment of CSHs including surgery and radiosurgery. Methods: A modified Dolenc epidural approach was performed in 22 patients and the intradural approach was used in 4. The tumor dissection was performed at the cranial nerve IV to V1 interval and V1 to V2 interval. Results: Gross-total/near-total resection was attained in 20 cases, subtotal resection in 5, and partial resection in 1. The mean follow-up period was 50 months (range, 6-200). Among the 23 patients with symptoms before surgery, complete remission was achieved in 14, improvement in 4, no change in 4, and deterioration in 1. The reviewed literatures shown there were no statistical differences of the improvement rate of ocular motility disorders between the surgery and radiosurgery. Conclusions: The reviewed literature and our experience suggest that surgical treatment of large and giant CSHs is a reasonable option. A relatively low postoperative morbidity can be achieved with minimal disturbance of cranial nerve III and early localization and preservation of VI. Radiosurgery could be an adjunct treatment for residual tumor.

Magnetic resonance imaging diagnosis and microsurgical treatment of cavernous sinus hemangiomas

To summarize the magnetic resonance imaging(MRI)features and microsurgical treatment of cavernous sinus hemangiomas(CSH). Twenty-three patients with surgically and pathologically verified CSH were reviewed. All patients underwent computed tomography(CT)and MR scan, 19 cases underwent MR diffusion-weighted imaging(DWI)and 7 underwent single voxel (1)H magnetic resonance spectroscopy((1)HMRS)before operation. The microsurgery through modified pterional approach was performed in 11 cases and 12 cases removal was achieved in combined fronto-temporal preauricular subtemporal approach. Nineteen cases with large tumors were treated by Leksell Gamma knife(LGK)before operation. CSHs were single, large, and spherical/lie gourd-shaped tumors across the inside and outside the sella. CSH showed equal or slightly low signal on T1WI, high signal on T2WI and FLAIR, homogeneous or heterogeneous great enhancement on MR enhancement scan 19 cases showed equal or slightly low signal on DWI, 7 cases showed no NAA, Cr, and Cho peak, and 6 cases showed Lip peak on (1)HMRS. In 23 cases, the tumors were totally removed in 18, subtotally removed in 3, and partially removed in 2. No perioperative death was reported. The postoperative symptoms were improved in 17 cases but remained unchanged in 4 cases two patients suffered from new nervous symptoms after the surgery, which were improved or cured after three weeks of treatment. In 5 patients who had received subtotal or partial removal of the lesions, LGK was performed postoperatively, which resulted in smaller residual tumors in 4 cases and unchanged tumor in one patient. CONCLUSIONS CSH has some unique MRI features, and therefore MRI is helpful to improve the preoperative localization and qualitative diagnosis. The microsurgery through modified pterional approach combined with fronto-temporal preauricular subtemporal approach is an effective procedure for CSH.

Clinical results of Gamma Knife surgery for cavernous sinus hemangiomas

The purpose of this study was to gain an understanding of the efficacy and safety of Gamma Knife surgery (GKS) for the treatment of cavernous sinus hemangiomas (CSHs). The authors report on 16 patients who underwent GKS as a primary or adjuvant treatment for CSH. Sixteen patients harboring CSHs (14 women and 2 men ranging in age from 21 to 65 years [mean 41.3 years]) underwent GKS at West China Hospital. In 4 patients the diagnosis was based on histological findings; in the other 12 patients it was based on findings on MR images. After patients were given a local anesthetic agent, the treatments were performed using a Leksell Gamma Knife model C. Gadolinium-enhanced MR images of T1-weighted, T2-weighted, and FLAIR sequences were obtained to determine the pretreatment location of the lesion. A mean peripheral dose of 13.3 Gy (range 11-14 Gy) was directed to the 40%-50% isodose line. The mean follow-up time in this study was 21.5 months (range 12-36 months). In 11 of 12 patients with symptoms, clinical improvement was reported at an average of 3.3 months (range 1-8 months) after GKS. Significant or partial tumor shrinkage was observed in 14 patients (87.5%) at the last follow-up. No new neurological impairments were reported after GKS. Magnetic resonance imaging may play an important role in the preoperative diagnosis of CSHs. Gamma Knife surgery may be a safe and effective primary or adjuvant treatment option for CSHs; however, long-term follow-up with more cases is needed to verify the benefits of this treatment.

Surgical management of large and giant cavernous sinus hemangiomas

Cavernous sinus hemangiomas (CSH) are rare vascular tumors within the cavernous sinus. Gamma Knife radiosurgery (GKS) is less effective for large and giant CSH than for smaller ones. In one of the largest single-institution series reported thus far, we present 22 patients with large (3–4 cm-diameter, six patients) and giant (>4cm, 16 patients) CSH treated surgically between 1994 and 2011. We also review related reports published since 1999 and further compare the treatment outcomes of surgery and radiosurgery. In the present study, a modified Dolenc’s epidural approach was performed in 18 patients and the intradural approach was used in four. Gross total or near-total resection was achieved in 18 patients, subtotal resection was achieved in three patients and partial resection was achieved in one patient. Postoperative ophthalmoparesis occurred in seven patients (two improved, four unchanged to preoperative, one new deficit), and decreased visual acuity occurred in one patient. The reviewed literature and our experience suggest that surgical treatment of large and giant CSH is a reasonable option. A relatively low postoperative morbidity can be achieved with minimal disturbance of cranial nerve (CN) III, particularly with early localization and preservation of CN VI. GKS could be an adjunct treatment for residual tumor.

Surgical treatment of large or giant cavernous sinus hemangiomas via epidural approach

To summarize the curative effect of surgically treated large or giant cavernous sinus hemangiomas (CSH) via epidural approach. From June 1999 to June 2011, 19 cases of CSH including 15 female and 4 male patients, ranging from 26 to 70 years (mean 45.3 years) were retrospectively reviewed. Ptosis/ocular motility disorders (10 cases), headache/ophthalmalgia (7 cases), decreased visual acuity (7 cases) and facial hyperesthesia (4 cases) were the most common presenting complaints. The epidural approach was taken and the tumor dissection was performed at the interval between trochlear nerve and ophthalmic nerve and the interval between ophthalmic nerve and maxillary nerve. The curative effect was followed up regularly. Gross total resection was attained in 13 cases, near-total resection in 4 cases, subtotal resection in 1 case and partial resection in 1 case. The follow-up period was between 6-144 months (mean 41.5 months). The results of last follow-up were as follows: among the 10 patients with ptosis/ocular motility disorders, complete remission was achieved in 5, improvement in 2, no change in 2 and lost follow-up in 1. Facial hypoesthesia symptom got complete remission in 2 patients and partial remission in the other 2 patients. The other symptoms mentioned above were all relieved. One patient got complication with impairment of vision and ocular motility disorders. Combined with skilled skull base techniques, surgical treatment of large or giant CSH via epidural approach is an effective method and the preservation of cranial nerves could be attained to an acceptable level.

Radiosurgery for cavernous sinus hemangiomas: medium- and long-term results

To describe the personal experiences of treating cavernous sinus hemangiomas (CSH) with gamma knife or cyberknife and evaluate the medium and long-term outcomes. From June 1999 to December 2008, 20 CSH patients were treated by radiosurgery (gamma knife or cyberknife). Among them, 11 had residual tumor after surgery and 9 were diagnosed by neuroradiology. All cases on magnetic resonance imaging (MRI) showed well-defined and homogeneous hyperintensity on T2-weighted images. The mean maximum diameter of tumors was 38.7 ± 9.3 mm (range: 23.0 - 60.6). The volume of tumors ranged between 4.1 - 52.6 cm(3) with a mean of (18.7 ± 12.5) cm(3). The tumor margin dose irradiated by gamma knife ranged from 9 to 16 Gy (mean 12.3 ± 2.3 Gy). The tumor margin dose irradiated by cyberknife was 20 - 21 Gy in 3 fractions. The mean follow-up period was (60 ± 32) months (range: 12 - 120). Follow-up imaging showed tumor volume decreased over 90% (n = 5), tumor regressed over 50% in volume (n = 9) and no change in tumor volume (n = 1). One patient with large tumor (irradiated 10 Gy) was operated by open surgery at 5 months after gamma knife. Four giant tumors decreased over 50% in volume after cyberknife. Neurologically, none of these patients showed any deterioration. And 16 patients demonstrated an obvious improvement after radiosurgery. At the last follow-up, there were no complications related to radiosurgery. Radiosurgery (Gamma knife or cyberknife) is a safe and effective modality for small- and medium-sized CSH. Fractionated Cyberknife proves to be an effective treatment for large or giant CSH. Thus radiosurgery will be an alternative option to surgery.

Diagnosis and surgical treatment of cavernous sinus hemangiomas: an experience of 20 cases

Objective To elucidate the advances of diagnosis and surgical treatment of the cavernous sinus hemangiomas (CSHs). Methods The data from 20 patients with the CSHs surgically treated by authors from 1996 through 2000 was analyzed retrospectively, and a review of relevant literature was conducted. Results These 20 cases accounted for 16.3% of all intracranial cavernous hemangiomas surgically treated in the same period at Huashan Hospital. The patients were aged from 32∼69 years with an average age of 47 years. There were 17 females and 3 males. The common clinical manifestations were visual loss, diplopia, headache, facial numbness and extraocular muscle palsy. Computed tomography (CT) and magnetic resonance imaging (MRI) were major preoperative diagnostic modalities, but demonstrated nonspecific features. The preoperative misdiagnostic rate was 38.9%. Of the 20 patients undergoing craniotomy via modified pterional approach with or without orbitozygomatic osteotomy, tumors were removed through epidural approach (EDA) in 13 cases, intradural approach (IDA) in 7 cases. Hypotension was induced during the operation in 2 cases. Total tumor removal was achieved in 12 cases (92.3%) in the EDA group and nil in the IDA group. Incomplete tumor removal was 1 case (7.7%) in the EDA group and 7 cases (100%) in the IDA group. One patient in the IDA group died of intracranial hemorrhage postoperatively. Compared with preoperative manifestations, cranial neuropathies at discharge were worsened in 76.9% of patients in the EDA group and 83.3% of patients in the IDA group, improved in 15.4% of patients in the EDA group and 16.7% of patients in the IDA group, unchanged in 7.7% of patients in the EDA group. Follow-up study (range, 1∼6 years; mean, 3 years) was available in 17 patients (89%). All patients in the EDA group improved without tumor recurrence. Nonimprovement (2 cases) and continued worsening (3 cases) occurred in the IDA group. In patients with tumor incompletely removed, the tumor enlarged in 2 cases, and unchanged or decreased in size in 3 cases, in which 2 cases underwent postoperative radiosurgery or radiotherapy. According to pathologic and MRI characteristics, the CSHs can be divided into two types, sponge-like type and mulberry-like type. Conclusion Cavernous hemangioma should be included in differential diagnosis for middle aged females with cavernous sinus tumors. Two types of the CSHs, sponge-like type and mulberry-like type, can be identified. The best microsurgical approach for the removal of the CSHs is epidural approach via the skull-base craniotomy. Radiosurgery should be considered for patients with incomplete tumor removal.
