There are previous reports investigating effectiveness of intraoperative magnetic resonance imaging (IO-MRI) in pituitary adenoma surgery but there is no clear data in the literature recommending when there is no need of intraoperative scan. This retrospective analysis was based on determining which patients does not need any IO-MRI scan following endoscopic endonasal pituitary adenoma surgery. Patients with functional or non-functional pituitary adenomas that were operated via endoscopic endonasal approach (EEA) between June 2017 and May 2019 were enrolled. Patients younger than 18 years old, patients who did not underwent IO-MRI procedure or not operated via EEA were excluded from the study. Hence, this study is designed to clarify if IO-MRI is useful in both functional and non-functional pituitary adenomas, functional adenomas did not split into subgroups. A total of 200 patients treated with pituitary adenoma were included. In Knosp Grade 0 – 2 group, primary surgeon’s opinion and IO-MRI findings were compatible in 150 patients (98.6%). In Knosp Grade 3 – 4 correct prediction were performed in 32 (66.6%) patients. When incorrectly predicted Knosp Grade 3 – 4 patients (n = 16) was analyzed, in 13 patients there were still residual tumor in cavernous sinus and in 3 patients there were no residual tumor. Fisher’s exact test showed there is a statistically significant difference of correct prediction between two different Knosp Grade groups (two-tailed P < 0.0001). Eighteen patients had a residual tumor extending to the suprasellar and parasellar regions which second most common site for residual tumor. Our findings demonstrate that there is no need of IO-MRI scan while operating adenomas limited in the sellae and not invading the cavernous sinus. However, we strongly recommend IO-MRI if there is any suprasellar and parasellar extension and/or cavernous sinus invasion.

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.

Abstract Two cases of trigeminal neurinoma located solely in the cavernous sinus are reported. Preoperatively, magnetic resonance imaging provided the accurate localization of the lesions, allowing precise planning of the surgical approach, that is, a subtemporal lateral approach and a pterional superior approach, respectively. The neurinomas inside the cavernous sinus were removed successfully, and the patients developed no new neurological deficits except for anesthesia in the 1st division of the trigeminal nerve. The characteristic magnetic resonance imaging findings of trigeminal neurinoma in the cavernous sinus are presented, and the different surgical approaches are discussed.

Abstract Magnetic resonance imaging (MRI), computed tomographic (CT) scanning, and angiography or digital subtraction angiography (DSA) were used preoperatively to evaluate 16 surgically proven cases of sellar tumor with extrasellar extension. There were 15 pituitary tumors and 1 schwannoma. The capabilities of MRI in evaluating these tumors were compared with CT scanning and angiography. Bone destruction and tumor calcification were better detected by CT scanning than by MRI. MRI was as effective as CT scanning in detecting a cyst or variation in tumor consistency. Neither MRI nor CT scanning was capable of distinguishing specific tumor types. In every case, MRI was superior to CT scanning for delineating spatial relationships of the tumor to the 3rd ventricle, the optic apparatus, adjacent brain, and parasellar vasculature. Vessel encasement by tumor was clearly seen on MRI when there was no direct indication of this on other studies. Cavernous sinus invasion was not demonstrated by CT scanning, but was indicated by MRI in 5 cases and was surgically confirmed in 3. MRI can provide more precise spatial information on extrasellar tumor extension. Vascular encasement and cavernous sinus invasion may be determined preoperatively. Treatment expectations and operative approaches can be guided by this information. When MRI is available, it is the test of choice for the preoperative evaluation of patients with suspected large pituitary gland (sellar region) tumors. Contrast-enhanced CT scanning and angiography can be used as supplementary studies to add information inherently unique to these techniques. (Neurosurgery 21:540-546, 1987)
