Trochlear Nerve Palsy

Abstract OBJECTIVE AND IMPORTANCE: Schwannomas originating from the trochlear nerve without neurofibromatosis are extremely rare. Thirty-four cases have previously been reported in the literature, and only 25 cases were pathologically diagnosed. In addition, intratumoral hemorrhage in intracranial schwannomas is also rare. Approximately 30 cases of intracranial schwannomas with intratumoral hemorrhage have been reported. CLINICAL PRESENTATION: A 42-year-old man presented with left hemiparesis and right trochlear nerve palsy. Magnetic resonance imaging revealed an abnormal cystic lesion beside the brainstem. His symptoms rapidly worsened after enlargement of the mass because of intratumoral hemorrhage. INTERVENTION: Gross total removal of the tumor was performed via the anterior transpetrosal approach. The tip of the trochlear nerve was fanned out and unified with the tumor. The tumor was diagnosed as a schwannoma. CONCLUSION: The patient's hemiparesis improved postoperatively, and he was discharged 1 week after the operation. Magnetic resonance imaging performed 4 months later revealed no regrowth of the tumor. Only right trochlear nerve palsy has persisted. This report is the second case of intratumoral hemorrhage from a trochlear nerve schwannoma.

Superior Oblique

Abstract Although head trauma is the leading cause of acquired trochlear nerve dysfunction, it receives little attention in the neurosurgical literature. A case is reported of closed head injury that resulted in a right superior oblique palsy in association with incoordination on the left side. Diagnostic imaging revealed a normal cranial computed tomographic scan and a left dorsal midbrain lesion on magnetic resonance imaging scan. The relevant anatomy is reviewed, as well as the action of the superior oblique muscle, its agonists and antagonists, and the clinical manifestations of superior oblique dysfunction. This case is one of the few we are aware of in which a relatively isolated trochlear nerve palsy is the result of a lesion that can be documented by diagnostic imaging, and the first in which the imaging modality is magnetic resonance imaging scan.

Facial Nerves

Tolosa–Hunt syndrome is characterized by unilateral retro-orbital headaches and cranial nerve palsies, usually involving cranial nerves III–VI. It is rare for other cranial nerves to be involved, although this has previously been reported. We report a 19-year-old woman presenting with typical features of Tolosa–Hunt syndrome but ultimately developing bilateral facial nerve palsies and enhancement of both facial nerves on magnetic resonance imaging. The patient presented with unilateral retro-orbital headaches and palsies of cranial nerves III–VI. She was diagnosed with Tolosa–Hunt syndrome but was non-compliant with her corticosteroid treatment due to side effects. She returned with progressive left followed by right facial nerve palsy. Her corresponding follow-up magnetic resonance imaging scans showed sequential enhancement of the left and right facial nerves. She ultimately had clinical improvement with IV methylprednisolone. To our knowledge, Tolosa–Hunt syndrome associated with bilateral facial nerve palsy and corroborative facial nerve enhancement on magnetic resonance imaging has not previously been described. Moreover, our patient’s clinical course is instructive, as it demonstrates that this atypical presentation of Tolosa–Hunt syndrome can indeed respond to corticosteroid treatment and should not be mistaken for other entities such as Bell’s palsy.

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.
