Radical Removal

Cavernous sinus cavernomas, a rare vascular malformation, represents 3% of all benign cavernous sinus tumors. Both clinical and radiological signs are important for differentiating this condition from other cavernous sinus diseases. The best treatment is radical removal tumor surgery; however, due to the tumor being located in the cavernous sinus, there are many difficulties in the surgery. We report a case of a 35-year-old female who only presented sporadical headache. After serial magnetic resonance imaging acquisitions, a tumor measuring 30 mm in the left cavernous sinus and heterogenous enhencement was observed. Then, the patient underwent an operation with an extradural basal temporal approach. Postoperatively, the tumor was safely gross total removed. The patient developed left oculomotor nerve palsy but fully recovered after 3 months of acupunture treatment, and developed persistent left maxillofacial paresthesia. The surgical treatment for cavernous sinus cavernomas may be considered a best choice regarding safety and efficiency.

Hunt Syndrome

Tolosa-Hunt Syndrome is a rare disease characterized by painful ophthalmoplegia affecting third, fourth, and/or sixth cranial nerve caused by non-specific inflammation in the cavernous sinus or superior orbital fissure of unknown etiology. We presented a 67-year-old female with Tolosa-Hunt Syndrome. She had a right-sided headache and periorbital pain with double vision. Examination showed right-sided ptosis, right-sided trochlear and abducens nerve palsy, and partial right-sided oculomotor nerve palsy with hypoesthesia in the area of the ophthalmic division of the trigeminal nerve. Magnetic resonance imaging of head and orbit showed altered signal intensity changes in the optic nerve and lateral rectus muscle. After steroid therapy, pain and ptosis were significantly improved in 72 hours. Tolosa-Hunt Syndrome is a diagnosis of exclusion, with clinical presentation, normal investigations, magnetic resonance imaging findings, and response to steroid therapy crucial in making the diagnosis.

Abstract OBJECTIVE We used gadolinium (Gd)-enhanced constructive interference in steady state (CISS) magnetic resonance imaging with the Leksell GammaPlan (LGP; Elekta AB, Stockholm, Sweden) system for accurate preoperative evaluation of the anatomic localization of intradural and/or extradural C2–C3 aneurysms. METHODS Anatomic localization of 8 unruptured aneurysms of the C2–C3 segment was evaluated using Gd-enhanced CISS imaging with LGP. Four patients diagnosed with intradural aneurysms, 1 with a combined intraextradural aneurysm, and 1 with an intracavernous aneurysm underwent operation. The aneurysmal localizations diagnosed preoperatively by Gd-enhanced CISS imaging with LGP were compared with intraoperative findings. RESULTS By use of Gd-enhanced CISS imaging with LGP, 3-dimensional visualization of the internal carotid artery, aneurysms at the C2–C3 segment, optic nerve, oculomotor nerve, cavernous sinus, and anterior clinoid process was possible in 8 patients. The localization of intradural or combined intra-extradural aneurysms was diagnosed on the basis of the oculomotor nerve and the cavernous sinus depicted in 3-dimensional images. The oculomotor nerve and the cavernous sinus serve as landmarks for the proximal ring on images of the carotico-oculomotor membrane. Intradural or intra-extradural localization of C2–C3 aneurysms with this novel technique was in complete agreement with intraoperative findings in 6 surgical cases. CONCLUSION This study demonstrated the utility of Gd-enhanced CISS imaging used with LGP for accurate preoperative localization of intradural and/or extradural aneurysms at the C2–C3 segments.

The aim of the review was to summarize information on clinical manifestations, diagnostic features, as well as methods for correction of scar defects after cesarean section (CS) outside pregnancy. Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.

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.
