Fourth Nerve Palsy

Objectives. Schwannomas originating from the trochlear nerve are extremely rare; only 30 cases have been reported in the literature. Many operative approaches have been utilized for lesion resection, but the advantages of the anterior transpetrosal approach are numerous and include excellent exposure, minimal extradural retraction of the temporal lobe, and minimal cerebrospinal fluid leaks. We report the second case of a trochlear schwannoma resected via the anterior transpetrosal approach.Setting. A 64-year-old male presented with 3-month history of diplopia and headaches. On physical examination, he was found to have a right fourth nerve palsy. Brain magnetic resonance imaging revealed a mass within the right ambient cistern compressing the adjacent midbrain. A right-sided anterior transpetrosal approach was used—which confirmed that the trochlear nerve entered the mass—to achieve gross total resection. Pathological examination confirmed diagnosis of schwannoma. The patient was discharged on postoperative day 3. He experienced a persistent fourth nerve palsy postoperatively with an otherwise normal neurological examination. Follow-up imaging confirmed complete removal of the tumor.Conclusion. The anterior transpetrosal approach is an excellent approach for removal of trochlear schwannomas involving the cisternal course of the trochlear nerve. It affords complete visualization of this anatomical region while introducing minimal morbidity.

Background Kawasaki disease (KD) is an acute multisystem vasculitic syndrome that predominantly affects infants and young children. Neurological complications are rare in patients with KD and the diagnosis is challenging. We report a case of KD that manifested as bilateral facial nerve palsy and meningitis. Case report A 6-month-old boy presented with a 10-day history of fever. Four days before admission, the patient developed a rash, conjunctival injection, perioral and perianal excoriation, and bilateral facial nerve palsy. Brain magnetic resonance imaging was normal. Echocardiography showed dilated coronary arteries and coronary artery aneurysms. A cerebrospinal fluid examination showed an elevated leukocyte count. A diagnosis of KD was made, and the patient was treated with gamma globulin and aspirin. The patient’s fever subsided on the following day and the right-sided facial nerve palsy was relieved 1 month later. An 18-month follow-up showed that the left-sided facial nerve palsy persisted and the patient’s condition remained stable. Conclusion KD manifesting as bilateral facial nerve palsy and meningitis is extremely rare. Clinicians should be aware of this condition, and early diagnosis and appropriate treatment should be emphasized.

A 64-year-old man with a midbrain cavernoma and prior bleeding presented with a 1-week history of diplopia, partial left oculomotor nerve palsy, and worsening dysmetria and right-sided weakness. MRI revealed a hemorrhagic left tectal plate and midbrain cavernoma. A left suboccipital supracerebellar transtentorial approach in the sitting position was performed for resection of his lesion utilizing the lateral mesencephalic sulcus safe entry zone. Postoperatively, he developed a partial right oculomotor nerve palsy; imaging depicted complete resection of the cavernoma. He recovered from the right third nerve palsy, weakness, and dysmetria, with significant improvement of his partial left third nerve palsy.The video can be found here: https://youtu.be/ofj8zFWNUGU.

Miller-Fisher syndrome (MFS) is a rare condition characterized by the classical triad of ophthalmoplegia, ataxia, and areflexia (Fisher, 1956). It is considered a variant of Guillain-Barré syndrome (GBS) with which it may overlap, or it can occur in more limited forms. We report a case of a thirty-five-year-old male who presented with a six-day history of diplopia, following a recent chest infection. On examination, he was found to have bilateral sixth nerve palsy, bilateral fourth nerve palsy, bilateral areflexical mydriasis, ataxia and total absence of reflexes. After excluding other conditions, a diagnosis of Miller-Fisher syndrome was made. The patient was administered intravenous immunoglobulin and made an uneventful recovery.

Radial nerve palsy was induced by radial nerve compression, which was often caused by humerus bone fracture. This leads to pain, weakness, or loss of function mostly in the wrist, hand, and fingers. We reported a case of a 24-year-old male patient with complaints of swelling of the right-hand wrist joint and pain during extension and flexion while moving. He had a three-month history of mild displaced humeral shaft fracture from a traffic accident and an intramedullary Ender nailing was performed. He now has been admitted with swelling in his right wrist joint and pain while moving his hand. The case was diagnosed as Radial nerve palsy. Surgery was performed, the proximal and distal ends of the radial nerve were separated at the humeral bone's surface. The radial nerve stumps were enough long to be sutured. Our one-month follow-up shows no complications. The majority cases of radial nerve palsy will resolve within a few weeks after surgery, as our patient did, and the most prominent is patient education.

Abstract Trigeminal schwannomas are benign lesions arising from the Schwann cells of the trigeminal nerve. This is an unusual tumor that accounts for less than 0.4% of intracranial pathologies, even though they are the second most frequent schwannoma after the vestibular schwannoma. The tumor spreads along the natural course of the V nerve at its cisternal portion, along the ganglion inside Meckel's cave or through its peripheral division. Even though the tumor can reach great size and become multicompartmental. We present a 51-yr-old woman, with an history of 3 mo of incapacitating facial pain, that was found on examination to be on the territory of the third division of the trigeminal nerve on the right side. The MRI depicted a large homogeneous enhancing lesion at the base of the right middle fossa with extension through the petrous apex to the most superior and medial part of the posterior fossa. The patient was operated by the senior author, through a middle fossa approach, dissecting between the two layers of the middle fossa dura (the apparent inner and the true outer layer of the cavernous sinus), the so called middle fossa “peeling”. We achieved total resection of the tumor, but the patient presented after surgery with facial nerve paresis. This is thought to be related to geniculate ganglion manipulation, as it was unprotect by bone at the middle fossa and the patient maintained lacrimal function (post-geniculate alteration). It resolved completely after 6 mo. The patient consented to publication of her images.

Background. Pituitary apoplexy (PA) is a clinical syndrome caused by acute ischemic infarction or hemorrhage of the pituitary gland. The typical clinical presentation of PA includes acute onset of severe headache, visual disturbance, cranial nerve palsy, and altered level of consciousness. Case Report. A 78-year-old man presented to the emergency department with one-day history of ptosis and diplopia and an acute-onset episode of altered level of consciousness which was resolving. He denied having headache, nausea, or vomiting. Physical examination revealed third-cranial nerve palsy and fourth-cranial nerve palsy both on the right side. Noncontrast computed tomography (CT) scan of the head was unremarkable. Brain magnetic resonance imaging (MRI) showed a pituitary mass with hemorrhage (apoplexy) and extension to the right cavernous sinus. The patient developed another episode of altered level of consciousness in the hospital. Transsphenoidal resection of the tumor was done which resulted in complete recovery of the ophthalmoplegia and mental status. Conclusion. Pituitary apoplexy can present with ophthalmoplegia and altered level of consciousness without having headache, nausea, or vomiting. A CT scan of the head could be negative for hemorrhage. A high index of suspicion is needed for early diagnosis and timely management of pituitary apoplexy.

A 19-year-old young woman was admitted to our Unit for irregular menstrual cycles within 40- to 60-day intervals for 7 months. She had no history of abdomino-pelvic surgery or acute pelvic pain. Pelvic magnetic resonance imaging revealed a right ovarian mass (Figure1A & B), measuring 6.0 cm X 5.1 cm X 5.0 cm. The patient underwent laparoscopy. At the laparoscopic examination, we evidenced a right ovarian teratoma about 6.0 cm X 6.0 cm and a small mesosalpinx cyst about 2.5 cm X 2.0 cm on the right fallopian tube (Figure 2A). On the left, neither fallopian tube nor ovary was detected (Figure 2B). We performed laparoscopic cystectomy and sutured residual ovarian tissues for hemostasis. Subsequent urinary ultrasonography demonstrated a normal urinary tract without any congenital anomaly. The pathological examination confirmed the diagnosis of mature teratoma and right mesosalpinx serous cyst. The patient was successfully discharged at the third day with no complications.

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.

Abstract We describe the case of a 42-yr-old female patient with a 2-yr history of headache that has progressively worsened. Physical examination revealed no neurological deficit. Magnetic resonance imaging showed a large tumor of the left lesser sphenoid wing that enhanced with gadolinium and produced displacement of the midline and the Sylvian fissure. A thorough analysis of the origin of the tumor was done to establish the surgical strategy. With the patient positioned supine with the head slightly turned to the right side, fixed in a 3-pin head clamp, a pterional craniotomy was performed. Since the origin of the tumor is in the lesser wing an early extradural devascularization of the tumor was done with drilling out all the hyperostotic bone of the lesser sphenoid wing, including the lateral base of the anterior clinoid process. Intradural debulking and resection showed the effect of extradural devascularization with an important decrease in bleeding, allowing the total resection of the tumor. An immediate postop magnetic resonance showed a complete removal of the tumor. The patient presented a paresis of the oculomotor nerve that completely resolved in the 3-mo follow-up. In the following video illustration, we narrate this operative case and highlight the nuances of this approach.1 The patient has given assent and written consent for videos, images, or clinical or genetic information to be published.

Hypertrophic Cranial Pachymeningitis

We report a rare case of granulomatosis with polyangiitis (GPA) presenting with hypertrophic cranial pachymeningitis (HCP), abducens nerve palsy, and stenosis of the internal carotid artery (ICA). A 59-year-old Japanese man presented with a year history of nasal obstruction and a 2-month history of slight headache. Histopathological examination of the granulomatous mucosa in the ethmoid sinuses resected by endoscopic sinus surgery revealed necrotizing vasculitis with multinucleated giant cells. The patient was diagnosed with the limited form of GPA as a result of the systemic examination. He declined immunosuppressive treatment. Eighteen months after the diagnosis of GPA, he presented with diplopia and severe headache. Though nasal findings indicating GPA were not observed in the nasal cavity, CT scan revealed a lesion of the right sphenoid sinus eroding the bone of the clivus. Gadolinium-enhanced MRI of the brain showed thickening of the dura mater around the right cavernous sinus and clivus. Magnetic resonance angiography and cerebral angiography revealed narrowing at the C5 portion of the ICA. Intravenous methylprednisolone pulse therapy followed by oral prednisolone and cyclophosphamide resolved headache and dramatically improved HCP and stenosis of the ICA.
