Infection may play an important role in the pathogenesis of alveolar osteonecrosis following facial herpes zoster: a case report and literature review.

BACKGROUND: Herpes zoster (HZ) is one of the most common skin diseases caused by viruses. Facial HZ develops when the varicella-zoster virus affects the trigeminal nerve, and alveolar osteonecrosis is a rare complication. However, the exact pathogenesis of postherpetic alveolar osteonecrosis remains unclear. CASE DESCRIPTION: We encountered a patient who presented to the dermatology clinic with facial HZ and tooth exfoliation in the upper right jaw, and panoramic radiography revealed decreased bone density and poor alveolar socket healing in his right maxilla. Biopsy of the alveolar process revealed fragments of nonvital lamellar bone, which were devoid of osteoblasts and osteocytes and were surrounded by numerous neutrophils and bacterial aggregates. Thus, the diagnosis of alveolar osteonecrosis following facial HZ was confirmed. He then underwent resection of the osteonecrotic tissue. The pathological findings of postoperative tissue were similar to those of previous biopsies. Varicella-zoster virus and multiple types of bacteria were detected through next-generation sequencing, and the species of bacteria were consistent with the results of bacterial culture. Antibiotics and valaciclovir were administered during the perioperative period. The patient showed good recovery at the 9-month follow-up. CONCLUSIONS: The coexistence of bacterial and viral infection may play an important role in the pathogenesis of alveolar osteonecrosis following HZ. To our knowledge, we are the first to directly explore microbial pathogens in a case of postherpetic alveolar osteonecrosis through next-generation sequencing and bacterial culture. We recommend that oral examinations be carefully conducted for patients who are diagnosed with facial HZ, even if their facial rashes have faded away. We suggest that a prolonged and full-dose antiviral therapy course may be beneficial for the treatment of facial HZ with intraoral lesions. The implementation of dental preventive measures should be considered for patients with facial HZ. The application of antibiotics and excision of necrotic bone may reduce the abundance of bacteria in lesions and improve wound healing.

Pain type and neuropathic pain components in acute herpes zoster.

OBJECTIVES: The aim of this study was to investigate the pain type (nociceptive or neuropathic) and neuropathic pain components in patients with acute herpes zoster (HZ). METHODS: Patients with acute HZ referred to the outpatient Dermatology and Venereology clinic between January 2021 and January 2022 were retrospectively detected. The demographic data including gender and age, rash localization, pain severity, and neuropathic pain components were recorded. Pain severity and neuropathic pain components were evaluated using a Visual Analog Scale (VAS) and Douleur Neuropathique 4 (DN4), respectively. RESULTS: The study included a total of 58 patients, comprising 33 females and 25 males. Of these patients, 35 (60.3%) were found to have neuropathic pain. Itching, burning, pins and needles, and tingling were the most frequently reported neuropathic pain signs and symptoms. The proportion of female patients with neuropathic pain was found to be significantly higher than that of male patients (p=0.021). No significant differences were observed in the distribution of pain across different body sites or in the age of patients with neuropathic pain (p>0.05). Itching was significantly more common in younger patients (p=0.02). CONCLUSION: In conclusion, the study found that over half of the patients with acute HZ experienced neuropathic pain, and this was more frequently observed in female patients. Analysis of different components of neuropathic pain showed significant differences in age, gender, and site distribution. The findings of this study may have important implications for the manage-ment and treatment of acute HZ.

[Left mandibular osteonecrosis following herpes zoster of the third branch of left trigeminal nerve: A case report].

Herpes zoster of trigeminal nerve was a common skin disease caused by varicella-zoster virus infection. Simple involvement of the third branch of trigeminal nerve was rare, and so were oral complications such as pulpitis, periodontitis, spontaneous tooth loss, bone necrosis, etc. This article presented a case of herpes zoster on the third branch of the left trigeminal nerve complicated with left mandibular osteonecrosis. We reported the case of a 64-year-old man with sudden pain in the left half of the tongue 1 month ago, and then herpes on the left facial skin appeared following with acute pain.The local hospital diagnosed it as herpes zoster and treated it with external medication. A few days later, he developed gum pain in the left mandibular posterior tooth area. He was admitted to Peking University School and Hospital of Stomatology one week ago with loose and dislodged left posterior tooth accompanied by left mandibular bone surface exposure. Clinical examination showed bilateral symmetry and no obvious restriction of mouth opening. Visible herpes zoster pigmentation and scarring on the left side of the face appeared. The left mandibular posterior tooth was missing, the exposed bone surface was about 1.5 cm×0.8 cm, and the surrounding gingiva was red and swollen, painful under pressure, with no discharge of pus. The remaining teeth in the mouth were all Ⅲ degree loosened. Imageological examination showed irregular low-density destruction of the left mandible bone, unclear boundary, and severe resorption of alveolar bone. The patient was diagnosed as left mandibular osteonecrosis. Under general anesthesia, left mandibular lesion exploration and curettage + left mandibular partial resection + adjacent flap transfer repair were performed. The patient was re-exmained 6 months after surgery, there was no redness, swelling or other abnormality in the gums and the herpes pigmentation on the left face was significantly reduced. Unfortunately, the patient had complications of postherpetic neuralgia. This case indicate that clinicians should improve their awareness of jaw necrosis, a serious oral complication of trigeminal zoster, and provide early treatment. After the inflammation was initially controlled, surgical treatment could be considered to remove the necrotic bone, curettage the inflammatory granulation tissue, and extraction of the focal teeth to avoid further deterioration of the disease.

Acute gastric dilatation with segmented abdominal paresis as a rare manifestation of herpes zoster: a case report and review of the literature.

BACKGROUND: Herpes zoster is a common disease that can affect men and women at any age. Sensory neuropathy is the most common complication while motor neuropathy of the abdominal muscles is rare complication appearing in ~ 0.7% of patients. Furthermore, visceral nerve involvement causing gastroparesis is an extremely rare postherpetic complication. We present an extremely rare case of acute gastric dilatation with segmented abdominal paresis as a rare manifestation of herpes zoster infection. CASE PRESENTATION: A 91-year-old Asian man was admitted to hospital with 2-day history of vomiting and left abdominal protrusion. He was previously treated for a rash on the left abdominal wall as herpes zoster infection with oral valaciclovir 2 weeks prior. On physical examination, characteristic herpes zoster rash scars and an ipsilateral abdominal bulge were observed on the left side. Computed tomography revealed no abdominal wall defect, mass, or stenosis. Remarkable distension of the stomach, asymmetrical left flank wall bulge, and a thinner abdominal wall on the left compared with the right side were shown. He was diagnosed as acute gastric dilatation owing to gastroparesis and segmental paresis of the abdominal musculature associated with herpes zoster infection. The patient showed significant improvement in symptoms and abdominal paresis within a month of conservative treatment, including nasogastric tube decompression and mosapride administration. CONCLUSION: Acute gastric dilatation with abdominal paresis is an extremely rare complication of herpes zoster infection, and to date there have been no reports in the literature. It alerts us that, when examining patients with abdominal bulge, we should be conscious of this rare pathology for the optical diagnosis, avoiding unnecessary invasive examination or surgical exploration.

Associations between organic erectile dysfunction and the risk of herpes zoster and postherpetic neuralgia in men.

BACKGROUND: Whether erectile dysfunction (ED) leads to considerable stress for affected men remains unclear? In this study, we investigated whether organic ED (OED) is associated with increased risks of herpes zoster (HZ) and postherpetic neuralgia (PHN). METHODS: A representative subset of Taiwan's National Health Insurance Research Database was employed for this study. Enrollees with OED from the years 2000 to 2018 were selected. To ensure comparability between the case and control groups, we implemented 1:1 propensity score matching based on age, index year, comorbidities, and medications. RESULTS: The case group included 20,808 patients with OED, while the control group consisted of 20,808 individuals without OED. The OED group exhibited a significantly elevated risk of HZ (adjusted hazard ratio [aHR] = 1.74) and PHN (aHR = 1.56) compared to the non-OED group. CONCLUSIONS: Men experiencing OED seem to face elevated risks of HZ and PHN compared to those without OED. ED may serve as a warning sign for individuals at HZ risk.

Herpes zoster of posterior division of mandibular branch of trigeminal nerve.

Herpes zoster is a disease caused by the reactivation of dormant varicella zoster virus present in the sensory root ganglion. It presents with a vesicular rash on an erythematous base similar to that seen in classical varicella, however, with only a single dermatomal distribution. The rash is usually seen throughout the affected dermatome as the dorsal root ganglia for each dermatome are clustered together. We present a case of an otherwise healthy male who developed a vesicular rash confined to the distribution of the posterior division of the mandibular nerve. Though the entire mandibular nerve arises from a single ganglion, the skin area supplied by the anterior division of the mandibular nerve was spared. This case provides evidence to show that there is anatomic segregation of cell bodies of nerves traversing anterior and posterior divisions of mandibular division in the trigeminal ganglion and that partial involvement of a sensory root ganglion is possible in immunocompetent patients.

Radiofrequency regulation of the sphenopalatine ganglion in managing herpes zoster ophthalmicus neuralgia: A case series.

INTRODUCTION: Trigeminal herpes zoster, which comprises 10% to 20% of cases of herpes zoster, often leads to severe pain in the ophthalmic branches. Current treatments, including drug therapy and minimally invasive interventions, have limitations; accordingly, there is a need to explore alternative approaches. This study aimed to evaluate the efficacy and safety of computerized tomography (CT)-guided pulsed radiofrequency of the sphenopalatine ganglion in patients with intractable trigeminal herpetic pain. PATIENT CONCERNS: Three patients with intractable trigeminal ophthalmic zoster neuralgia were studied. All patients complained of bursts of headache, which occurred at least 10 times a day, usually in the periorbital and frontal regions. Conventional treatments, including oral medications and radiofrequency therapy targeting the trigeminal-semilunar ganglion and supraorbital nerve, could not sufficiently provide relief. DIAGNOSIS: Two patients were diagnosed with herpes zoster in the ocular branch of the trigeminal nerve with conjunctivitis, while one patient was diagnosed with postherpetic neuralgia in the ocular branch of the trigeminal nerve. INTERVENTIONS: This study employed a novel approach that involved CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion. OUTCOMES: In all three patients, pain relief was achieved within 1 to 3 days after treatment. During the follow-up, one patient had pain recurrence; however, its severity was ≈ 40% lower than the pretreatment pain severity. The second patient had sustained and effective pain relief. However, the pain of the third patient worsened again after 2 months. The average follow-up duration was 3 months. None of the enrolled patients showed treatment-related adverse reactions or complications. CONCLUSION: Our findings indicated that CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion was a safe and effective intervention for pain in patients with trigeminal ophthalmic zoster neuralgia, suggesting that it may be a therapeutic option if other treatments fail.

Circadian changes of autonomic function in patients with zoster-associated pain: A heart rate variability analysis.

OBJECTIVE: To investigate the circadian changes of the autonomic function in patients with zoster-associated pain (ZAP). METHODS: A total of 37 patients with ZAP from April 2022 to October 2022 were enrolled as the observation group, and 37 normal volunteers at the same time were selected as the control group. All participants were required to wear a 24-h Holter, which was used to compare the heart rate variability (HRV) between the two groups. HRV analysis involved time- and frequency-domain parameters. RESULTS: There was no statistically significant difference in general information between two groups. Patients with ZAP had an increased mean heart rate and decreased the standard deviation of normal-to-normal (SDNN) R-R interval, the root mean square of the differences (RMSSD) in successive RR interval, low frequency (LF), and high frequency (HF) compared with control groups in all periods (p < .05). The ratio of LF/HF between two groups had no significant difference (p = .245). SDNN had no significant difference between day and night in the control group (p > .05), whereas SDNN of ZAP patients in night period was reduced than that in day period (p < .001). The level of RMSSD during the day was lower than those at night in the control group (p < .05), whereas no significant difference of RMSSD between two periods was observed in patients with ZAP (p > .05). CONCLUSION: The results of this study indicated that ZAP contributes to the decline of autonomic nervous system (ANS) function, especially parasympathetic components. The patients with ZAP lost parasympathetic advantage and had a worse ANS during the night.

Transforaminal Epidural Block and Erector Spinae Plane Block to Manage Acute Zoster-Associated Pain: A Retrospective Case-Control Study.

Background and Objectives: Achieving adequate pain reduction in the acute phase of herpes zoster is essential for preventing postherpetic neuralgia (PHN). For this purpose, appropriate antiviral medications, oral analgesic medications, and various nerve block methods could be applied. Erector spinae plane block (ESPB) is a simple, novel ultrasound-guided block technique, and its use has increased because the procedure is convenient and relatively safe. Although several cases have reported the zoster-associated pain (ZAP) control effect of ESPB, the efficacy of ESPB has not been compared with that of other types of nerve blocks for managing ZAP. This study aimed to compare the efficacy of ESPB with that of other types of nerve blocks for managing ZAP. Study Design: Retrospective case-control study. Materials and Methods: Medical records of 53 patients with acute thoracic herpes zoster were reviewed. We divided the participants into two groups: patients who received transforaminal epidural injection (TFEI) (n = 32) and those who received ESPB (n = 21). The efficacy of the procedure was assessed by a numerical rating scale (NRS) and by recording patient medication doses before the procedure and at 1 week, 1 month, 2 months, and 3 months after the procedure. Results: The time required for pain intensity to decrease to NRS ≤ 2 was not significantly different between the groups. The rate of medication discontinuation also was not different between the groups. There was no significant difference between the two groups in the proportion of clinically significant PHN (NRS ≥ 3) at any time point. Limitations: The relatively small sample size from a single center and the retrospective nature of the study served as limitations. Conclusions: The clinical effects of ESPB and TFEI were similar in patients with acute thoracic herpes zoster. ESPB could be considered an interventional option for ZAP management.

Neuralgia in the occipital region associated with ipsilateral trigeminal herpes zoster: Three case reports.

BACKGROUND: Nerve fibers related to pain and temperature sensation in the trigeminal nerve territory converge with the upper cervical spinal nerves from the level of the lower medulla oblongata to the upper cervical cord. This structure is called the trigemino-cervical complex and may cause referred pain in the territory of the trigeminal or upper cervical spinal nerves. CASE SERIES: Here, we report three cases of paroxysmal neuralgia in the occipital region with mild conjunctivitis or a few reddish spots in the ipsilateral trigeminal nerve territory. The patients exhibited gradual progression of these reddish spots evolving into vesicles over the course of several days, despite the absence of a rash in the occipital region. The patients were diagnosed with trigeminal herpes zoster and subsequently received antiherpetic therapy. Remarkably, the neuralgia in the occipital region showed gradual amelioration or complete resolution before the treatment, with no sequelae reported in the occipital region. DISCUSSION: The trigemino-cervical complex has the potential to cause neuralgia in the occipital region, as referred pain, caused by trigeminal herpes zoster. These cases suggest that, even if conjunctivitis or reddish spots appear to be trivial in the trigeminal nerve territory, trigeminal herpes zoster should be considered when neuralgia occurs in the ipsilateral occipital region.

Professor FU Wenbin's experience of "acupuncture-moxibustion-consolidation" holistic idea in treatment of laryngeal herpes zoster with vocal cord paralysis. / 符文彬教授整合思维"一针二灸三巩固"模式治疗喉带状疱疹伴声带麻痹的临床经验.

This paper introduces professor FU Wenbin's clinical experience in the treatment of laryngeal herpes zoster with vocal cord paralysis, using the holistic mode of treatment, in which, acupuncture, moxibustion and consolidation regimens are integrated. Regarding the core pathogenesis of the disease, the invaded exogenous toxic heat is transformed into fire that flows to the throat. Soothing liver and releasing heat is the general principle of treatment, guiding the entire process of treatment. For acupuncture regimen, the filiform needling is used and the acupoint prescription is composed of Baihui (GV 20), Yintang (GV 24+), Lianquan (CV 23), the four-gate points (bilateral Hegu [LI 4] and Taichong [LR 3]), the group points for conducting qi back to the primary (Zhongwan [CV 12], Xiawan [CV 10], Qihai [CV 6] and Guanyuan [CV 4]), as well as bilateral Fengchi (GB 20), Wangu (GB 12) and Yifeng (TE 17). Besides, the pricking technique is delivered to the posterior wall of the pharynx for soothing the liver, regulating the spirit, reducing the heat and benefiting the throat. For the moxibustion regimen, moxibustion is applied to Fengchi (GB 20), Feishu (BL 13), the four-flower points (bilateral Geshu [BL 17] and Danshu [BL 19]), Shenshu (BL 23) and Mingmen (GV 4), which nourishes the spleen and stomach and reduces the heat pathogen through the heating action of moxibustion specially. In the stage of consolidation, the bloodletting and cupping technique is used at Xinshu (BL 15), Ganshu (BL 18) and Jianjing (GB 21) to eliminate the liver stagnation and the intradermal needling is delivered to sustain the needling stimulation and consolidate the therapeutic effect.

Hospitalizations of patients with herpes zoster in Poland during 2012-2021: A population-based study.

INTRODUCTION: The varicella-zoster virus (VZV) is an infectious agent that causes both chickenpox and herpes zoster/shingles (HZ). This infection can take various clinical forms, result in permanent complications, and be a marker of immunosuppression, e.g. in the course of a neoplastic disease. The aim of this study is to analyze epidemiological trends in hospitalization and hospital mortality rate among HZ patients in Poland (2012-2021). METHODS: Our study is a population-based, retrospective analysis of hospital discharge records of patients with HZ. Data were obtained from the National Institute of Public Health in Poland, and they covered the period from 2012 to 2021. All hospitalization records with primary or secondary ICD-10 B02 code diagnosis were included in the study. RESULTS: We analyzed the total number of 23,432 hospital discharge records of HZ patients in 2012-2021. The study group consisted of 22,169 (94.6 %) hospitalization records of first-time diagnosis of HZ in hospitalized patients: 9,309 males (42 %) and 12,860 females (58 %). In this group, 70.3 % were patients over 60 years old. The mean and median age was 64 and 69 years, respectively. The mean annual first-time hospitalization rate for HZ was estimated to be 5.8 per 100,000 person-years (95 % CI: 4.8-6.7 per 100,000 person-years). The hospitalization rate for HZ was similar during 2012-2019. There was a significant decrease in hospitalizations in 2020-2021 in comparison with the previous years (R2 = 0.42, p < 0.05). Women showed a higher hospitalization rate than men (p < 0.001). Urban residents had a higher hospitalization rate than rural residents (p < 0.001). In the analyzed period, 246 deaths were recorded (1.1 % of all hospitalized HZ patients) -119 males and 127 females. CONCLUSIONS: The HZ-related number of hospitalizations and mortality in Poland are relatively low, but HZ is still a significant health problem. Risk factors include female gender, older age and residence in urban areas.

Combined Therapy of Paravertebral Nerve Pulsed Radiofrequency and Subcutaneous Block for Acute/Subacute Herpetic Neuralgia: A Retrospective Study.

OBJECTIVES: This retrospective study aimed to investigate the effectiveness and safety of early combined therapy with CT-guided paravertebral nerve (PVN), pulsed radiofrequency (PRF), and subcutaneous block on acute/subacute herpes zoster (HZ). METHODS: A total of 98 medical records were analyzed. All patients underwent CT-guided PRF on PVN immediately followed by a single subcutaneous block with lidocaine and dexamethasone in acute/subacute phase. The therapy efficacy was evaluated by pain numeric rating scale (NRS) and effective rate, which was defined as a percent of cases with a reduction in pain NRS>50% at day 1, week 2, 4, 12, and 24 after the procedure. The incidences of medication reduction and postherpetic neuralgia (PHN) were also retrieved. Further comparison was conducted between acute group (disease duration<30 days from HZ onset) and subacute group (30 day50% in prior medications amounted to 83% and the incidence of clinically meaningful PHN decreased to 23%. The clinical efficacy was more profound in acute group than in subacute group at every time points ( P <0.05). No severe complications occurred. DISCUSSION: Our data revealed surprising levels of pain relief by combination therapies of PRF and subcutaneous block targeting different sites of pain pathway, thus suggesting a valuable treatment option for acute/subacute herpetic neuralgia.

Time-varying association between herpes zoster infection and subsequent occurrence of stroke.

OBJECTIVES: The aim of this study was to investigate the shape of the time-varying relationship between herpes zoster infection, nominally shingles, and the occurrence of stroke. STUDY DESIGN: Retrospective cohort study. METHODS: Using the Italian Health Search Database, a cohort of patients aged ≥18 years who were registered between 2002 and 2021 was selected. In this cohort, a nested case-control analysis was used to model the time-varying distance (in months) between the dates of shingles and post-herpetic stroke, using a regression cubic spline, based on the odds of the occurrence of stroke compared with those without shingles. RESULTS: The dataset comprised 42,513 cases (51.1% males; mean age [stanndard deviation {SD}]: 71.0 [11.8] years) and 425,124 related controls (51.1% males; mean age [SD]: 70.9 [12] years). In the first 12 months following shingles diagnosis, a rapid increase in the risk of stroke was observed, reaching an odds ratio of 1.31 (95% confidence interval: 1.21-1.41); subsequently, there was some risk reduction and a new symmetric increase within the first 4.2 years of follow-up, thus shaping a bimodal distribution. Then, a new increase in the stroke risk was reported, although less steep, which was followed by a regular risk reduction (still 10% higher compared with those without shingles), resulting in a right-skewed relationship between the time from the shingles diagnosis and the occurrence of stroke. This association was no longer statistically significant 13.1 years after shingles diagnosis. CONCLUSIONS: This study demonstrated that the risk of post-herpetic stroke has a short- and long-term association according to a risk continuum relationship. These findings confirm the relevance of vaccination coverage for herpes zoster.

[Electrical dorsal root ganglion stimulation (DRGS) for the treatment of refractory postherpetic neuralgia]. / Elektricheskaya stimulyatsiya gangliya zadnikh koreshkov spinnogo mozga (DRGS) dlya lecheniya refrakternoi postgerpeticheskoi nevralgii.

Postherpetic neuralgia (PHN) is a rare complication of herpes zoster characterized by prolonged and excruciating pain. Traditional treatments for PHN, such as analgesics, anticonvulsants and antidepressants, do not always bring the desired result. One promising alternative that is attracting the attention of the scientific community is dorsal root ganglion stimulation (DRGS). This method focuses on targeted and precise targeting of the source of pain, providing a new level of effectiveness in the treatment of PHN. OBJECTIVE: A retrospective analysis of the technique and results of implantation of a permanent device for stimulating the spinal ganglia in patients with refractory PHN at the Burdenko Neurosurgical Center. MATERIAL AND METHODS: The study was conducted in 7 patients (5 men, 2 women) with refractory PHN in the period from 2018 to 2020. The age of the patients ranged from 57 to 84 years (average age 74±8.4). All patients were implanted with Boston systems (Precision or Spectra versions). Stimulation parameters: pulse width - 120-210 µs, frequency - 30-130 Hz, amplitude at the lower limit of the appearance of paresthesia with the possibility of increasing with increased pain up to 5 mA. The position of the electrode depended on the location of the pain. All systems were implanted under X-ray guidance. RESULTS: The duration of follow-up observation was more than 2.5 years. The average pain intensity one year after treatment was 3.42±2.45 points on the visual analogue scale (VAS) (a 62.3% decrease in intensity compared to baseline). In 3 (42.8%) patients, the result was characterized by us as «excellent¼ (intensity according to VAS decreased by 75% or more), in 1 (14.2%) - as «good¼ (intensity according to VAS decreased by 50-74%), in 1 (14.2%) - as «moderate¼ (VAS intensity decreased by 25-49% and in 2 (28.5%) as «unsatisfactory¼ (VAS intensity decreased by less than 25%, or postoperative complications occurred). CONCLUSION: Given the complicated nature of PHN, the use of dorsal ganglion stimulation appears to be a promising and innovative treatment approach. Further research is needed to introduce this technique into clinical practice for the treatment of patients suffering from PHN.

Rare Combination of Abducens Nerve Palsy and Optic Neuritis on the Same Side: Case Report and Review of 8 Patients in Literature.

The concurrent development of abducens nerve palsy and optic neuritis on the same side is rare. Here we presented an 82-year-old man who developed the combination of abducens nerve palsy and optic neuritis on the left side 2 months after the sixth inoculation of COVID-19 mRNA vaccine. In past history at 45 years old, he experienced subarachnoid hemorrhage and underwent surgery for the clipping of intracranial aneurysm. The patient had no systemic symptoms, such as general fatigue, fever, arthralgia, and skin rashes. Physical and neurological examinations were also unremarkable. Since the aneurysmal metal clip used at that time was not compatible with magnetic resonance imaging, he underwent computed tomographic (CT) scan of the head and showed no space-occupying lesion in the orbit, paranasal sinuses, and brain. As an old lesion, the anterior temporal lobe on the left side had low-density area with metallic artifact on the left side of the skull base, indicative of metal clipping. In 4 weeks of observation from the initial visit, he showed complete recovery of visual acuity and became capable of abducting the left eye in full degrees. We also reviewed 8 patients with the combination of abducens nerve palsy and optic neuritis in the literature to reveal that the combination of signs did occur in mild meningitis with rare infectious diseases and in association with preceding herpes zoster in the first branch of the trigeminal nerve. The course of the present patient suggested that the combination of signs might be vaccine-associated.
