The paper reports acupuncture treatment for one case of oculomotor nerve palsy after cranial-orbital communicating tumor surgery. The acupoint prescription was composed of the local acupoints of the eyes (Yansanzhen, Tijian, Cuanzhu [BL2], Yuyao [EX-HN4] and Sizhukong [TE23]), the acupoints on the head, face and neck (Yangbai [GB14], Sibai [ST2] and Fengchi [GB20]), Guanyuan (CV4) on the abdomen, and those on the four limbs (Hegu [LI4], Zusanli [ST36], Shenmai [BL62] and Zhaohai [KI6]). The point-to-point needling technique with the eyelid lifted was operated at Tijian, Cuanzhu (BL2), Yuyao (EX-HN4), and Sizhukong (TE23). Warm needling with moxa cone placed on the needle handle was operated at Guanyuan (CV4) and Zusanli (ST36), and the usual needling technique was delivered at the rest acupoints. The treatment was given once daily, discontinued for 1 day after every 6 treatments. One course of treatment was composed of 7 days, and 6 courses were required. After treatment completion, the upper eyelids were basically symmetrical and the bilateral eye cracks were equal, the double vision appeared occasionally. No recurrence and no aggravation were reported in 1 month of follow up visit.

OBJECTIVE

To describe the clinical presentation, management and outcome of a rare case of isolated oculomotor nerve palsy in an immunocompromised adult secondary to a central nervous system (CNS) tuberculoma.

This is a case report.

A Filipino male in his 30s developed severe throbbing headache followed by binocular diplopia and drooping of the right upper eyelid. Findings were compatible with a neurologically-isolated pupil-involving, complete oculomotor nerve palsy on the right. Brain magnetic resonance imaging demonstrated enlargement and contrast enhancement of the cisternal portion of the right oculomotor nerve. Serologic testing was positive for the human immunodeficiency virus (HIV) and syphilis. Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis and elevated protein. CSF polymerase chain reaction was positive for Mycobacterium tuberculosis (TB). The patient was treated with penicillin, quadruple anti-Koch’s, and anti-retrovirals. Eyelid position and ocular motility improved after treatment. Aberrant regeneration of the right oculomotor nerve was observed with elevation of the right eyelid on downgaze (pseudo-Graefe sign).

CNS tuberculoma may present as a neurologically-isolated oculomotor nerve palsy, particularly in immunocompromised individuals. In TB-endemic countries, like the Philippines, it should be considered in the differential diagnosis. Early recognition and appropriate antimicrobial therapy can lead to neurologic improvement.

OBJECTIVE: To analyze the clinical characteristics and genetic etiology of a child with Christianson syndrome (CS). METHODS: A 1-year-and-5-month-old boy with CS diagnosed at the First Affiliated Hospital of Zhengzhou University in April 2021 was selected as the study subject. Clinical data were retrospectively analyzed. Peripheral blood samples were obtained from the child and his parents, followed by genomic DNA extraction and whole exome sequencing (WES). Candidate variant was validated by Sanger sequencing. This study has been approved by the Medical Ethics Committee of the Hospital of Zhengzhou University (Ethics No. 2024-KY-1103-001). RESULTS: The child has manifested with seizures, microcephaly, and global developmental delay. WES revealed that he has harbored a novel de novo hemizygous nonsense variant of the SLC9A6 gene, namely c.1014G>A (p.W338*). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic. CONCLUSION The hemizygous c.1014G>A nonsense variant of the SLC9A6 gene probably underlay the pathogenesis in this child. Above discovery has expanded mutational spectrum of the SLC9A6 gene and enabled definite diagnosis of the child.

Dorsal midbrain syndrome (DMS) is a supranuclear palsy of vertical gaze characterized by conjugate upgaze palsy, light-near dissociation, convergence-retraction nystagmus, lid retraction, and skew deviation. Majority of cases are due to primary midbrain lesions such as strokes or neoplasms, or due to pineal gland tumors compressing the said area. Presented here is the case of a 57-year-old male who came in with a chief complaint of diplopia and the typical signs of DMS. Cranial tomography scan revealed a parenchymal hemorrhage at the left thalamocapsuloganglionic region, a rarely reported site of a primary lesion causing DMS. In this case, the syndrome may have been a consequence of the mass effects and perilesional edema associated with the thalamocapsuloganglionic hemorrhage, or may have been due to disruption of supranuclear inputs to the dorsal mibdrain. This case provides further evidence that DMS may arise from lesions without obvious involvement of the said region. This case also highlights the importance of a thorough physical examination to elicit the findings associated with DMS, and the need to correlate these with a keen analysis of diagnostic test results.

OBJECTIVE: To report on a rare case of Neurofibromatosis type 2 (NF2) manifesting as oculomotor nerve palsy and explore its genetic basis. METHODS: A patient with NF2 who had presented at Beijing Ditan Hospital Affiliated to Capital Medical University on July 10, 2021 was selected as the study subject. Cranial and spinal cord magnetic resonance imaging (MRI) was carried out on the patient and his parents. Peripheral blood samples were collected and subjected to whole exome sequencing. Candidate variant was verified by Sanger sequencing. RESULTS: MRI revealed bilateral vestibular Schwannomas, bilateral cavernous sinus meningiomas, popliteal neurogenic tumors, and multiple subcutaneous nodules in the patient. DNA sequencing revealed that he has harbored a de novo nonsense variant of the NF2 gene, namely c.757A>T, which has replaced a codon (AAG) encoding lysine (K) at position 253 with a stop codon (TAG). This has resulted in removal of the Merlin protein encoded by the NF2 gene from position 253 onwards. The variant was not found in public databases. Bioinformatic analysis suggested that the corresponding amino acid is highly conserved. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PVS1+PS2+PM2_Supporting+PP3+PP4). CONCLUSION The heterozygous nonsense variant c.757A>T (p.K253*) of the NF2 gene probably underlay the disease in this patient with an early onset, atypical but severe phenotype.

OBJECTIVES: Oculomotor nerve palsy is a kind of disease with many causes, showing eye movement disorders, abnormal eyelid position, and/or damage of the pupil. The etiology of oculomotor nerve palsy in different departments is different. The study discussed the etiology, localization of the lesion, and prognosis for oculomotor nerve palsy firstly diagnosed in department of ophthalmology. METHODS: Clinical data of 137 hospitalized patients with oculomotor nerve palsy at the Department of Ophthalmology, the First Medical Center of PLA General Hospital from 2009 to 2018 were retrospectively collected. The etiology and its distribution characteristics in different age groups, the location of the lesion, and the prognosis of patients were analyzed. RESULTS: In 137 patients, the top 3 causes for oculomotor nerve palsy were head trauma (38.69%), cavernous sinus lesions (12.40%), and orbital inflammation (9.49%). Other causes included intracranial aneurysm, the intracranial space-occupying lesion, cerebral vessel diseases, infection, orbital tumors, diabetes, the operation of nasal cavity. Traumatic oculomotor nerve palsy was more common in young adults aged 20-49 years and in the patients with cerebral vascular disease in elderly people aged 60-69 years, while diabetic oculomotor nerve palsy is common in middle-aged and elderly people aged 50-69 years. The age distribution of other etiological types was relatively balanced. Seventy-five cases of orbital apex lesions were due to trauma, inflammation, infection, and tumor; 40 cases of cavernous sinus lesions were due to inflammation, tumor, and thrombosis; 6 cases of subarachnoid lesions were due to aneurysms, tumors, and trauma; 5 cases were oculomotor nucleus lesions were due to infarction; 11 cases could not be allocated because of unknown etiology. After treatment, the corrected visual acuity of oculomotor nerve palsy side was not significantly improved. The patients with oculomotor nerve palsy caused by intracranial aneurysm, cerebrovascular disease, and diabetes mellitus had the highest proportion of partial or complete recovery from ptosis and ocular dyskinesia. CONCLUSIONS Oculomotor nerve palsy is a common cause of ophthalmoplegia and diplopia. Head trauma, cavernous sinus lesions, and orbital inflammation are the most common causes for oculomotor nerve palsy first diagnosed in ophthalmology department. Traumatic oculomotor nerve palsy is common in adolescents. Oculomotor nerve palsy caused by diabetes and cerebrovascular disease are common in the middle-aged and elderly people. Most of the lesions locate in the orbital apex and cavernous sinus. The prognosis of corrected visual acuity is poor. The prognosis of ptosis and ocular dyskinesia caused by intracranial aneurysm, cerebrovascular disease, and diabetes is good. Figuring out the cause timely and accurately is the basis and key to treat oculomotor nerve palsy.

Upon review, it is noted that recurrent painful ophthalmoplegic neuropathy (RPON) is a rare neurological syndrome characterized by recurrent unilateral headaches and painful ophthalmoplegia of the ipsilateral oculomotor nerve. As seen on brain MRI, thickening and enhancement of the oculomotor cranial nerve can be observed in these cases. We experienced a case of RPON in an adult patient who showed thickening and enhancement of the oculomotor nerve on gadolinium-enhanced 3D-FLAIR image. The authors report a case of RPON with a review of the literature.

Oculomotor nerve palsy limits the specific direction eyeball movement, and represents diplopia, mydriasis, and ptosis. The vascular-associated etiologies of oculomotor nerve palsy are the microvascular ischemia due to hypertension or diabetes, or compression of the nerve by the aneurysm. For the aneurysm, if not treated properly, it may result in mortality or severe neurological impairment. Thorough history taking, physical examinations, and proper imaging modality are needed to make an accurate diagnosis. A 76-year-old female with decreased mentality and anisocoria presented at our emergency department. An 83-year-old female presented with right ptosis and lateral-side deviated of the right eyeball. No definite lesion was noted on the initial non-contrast brain computed tomography (CT) and magnetic resonance imaging diffusion. An aneurysm was detected on CT angiography taken several hours later in the former patient. For the latter patient, a giant aneurysm was detected on magnetic resonance angiography that had been performed at another hospital 4 days earlier. These two patients underwent transfemoral cerebral angiography with coiling. They were discharged with no neurological sequelae.
