Systemic thromboembolism including multiple cerebral infarctions with middle cerebral artery occlusion caused by the progression of adenomyosis with benign gynecological tumor: a case report.

BACKGROUND: Adenomyosis, a benign gynecological disease, causes cerebral infarction. Similar to Trousseau's syndrome, it elevates cancer antigen 125 (CA125) and D-dimer levels; causes hypercoagulability; and results in cerebral infarction. However, no case of adenomyosis causing major cerebral artery occlusion and requiring endovascular thrombectomy has yet been reported. We report on a woman with middle cerebral artery occlusion caused by adenomyosis progression with a benign gynecological tumor and recurrent cerebral infarction. She was successfully treated by endovascular thrombectomy and hysterectomy. CASE PRESENTATION: A 48-year-old woman with heavy uterine bleeding was transported by ambulance to our hospital. Upon arrival, she presented with impaired consciousness. Laboratory test results revealed decreased hemoglobin (8.2 g/dL) and elevated D-dimer (79.3 µg/mL) levels. Radiological imaging revealed adenomyosis, a left ovarian tumor, multiple uterine myomas, and old and new bilateral renal infarctions. She experienced repeated episodes of excessive menstruation caused by adenomyosis and was scheduled for hysterectomy in 2 months at another hospital. After hospital admission, uterine bleeding stopped. However, 5 days after initial bleeding, she had another episode of heavy uterine bleeding and developed left hemiparesis and dysarthria 20 min later. Brain magnetic resonance imaging revealed bilateral multiple cerebral infarctions indicating right middle cerebral artery occlusion. Thus, endovascular thrombectomy was performed, and anticoagulant therapy was administered. Laboratory test results after thrombectomy revealed elevated CA125 (3536 U/mL) and CA19-9 (892 U/mL) levels. She was at a risk of recurrent heavy uterine bleeding leading to repeated cerebral infarction because of anticoagulant treatment. Therefore, we performed hysterectomy and ovariectomy 11 days after initial bleeding. Histopathological assessment revealed no malignancy. Although she developed asymptomatic pulmonary thromboembolism 14 days after initial bleeding, D-dimer and tumor marker levels returned to normal soon after gynecological surgery. At 15 months post-surgery, she had not experienced further ischemic events. CONCLUSIONS: Adenomyosis with benign gynecological tumors may be associated with elevated D-dimer and tumor marker levels; excessive menstruation; and anemia. It may cause systemic thromboembolism, including cerebral infarction. To our knowledge, no other study has reported that adenomyosis causes major cerebral artery occlusion requiring endovascular thrombectomy. Hysterectomy may be an effective radical treatment of this condition.

Multiple cerebral infarction diagnosed as Eosinophilic Granulomatosis with Polyangiitis by autopsy.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis of unknown cause involving the brain and accompanied by prominent eosinophilia. Intracardiac thrombosis is a major cardiac complication of EGPA that may cause thromboembolism. CASE PRESENTATION: A 53-year-old man presenting with abulia (consciousness disturbance) and left upper limb paralysis was admitted to our hospital. His case was complicated by penetrating branches, small vessel infarcts, and endocardial thrombosis in the right and left ventricle. Cardiomyopathy was also observed. Sixteen days after admission, the patient died from intracranial hemorrhage. Brain autopsy revealed two major findings: 1) large hemorrhagic infarction caused by cardiac embolism; and 2) granuloma and eosinophil infiltration. Vasculitis was accompanied by eosinophil infiltration in the cortical blood vessels and granuloma. CONCLUSIONS: In this case study, we report autopsy findings of brain infarction in a patient with EGPA and endocardial thrombosis. The brain infarction was caused by the cardiac embolisms and vasculitis.

A Case of Multiple Cerebral Infarction Preceding Acute Exacerbation of Idiopathic Thrombocytopenic Purpura.

BACKGROUND: Although it was suggested that idiopathic thromobocytopenic purpura (ITP) can be a paradoxical cause of cerebral infarction, previous reports indicate that cerebral infarction associated with ITP occurs when thrombocytopenia is already evident at the onset of cerebral infarction. CASE REPORT: We report a case of multiple cerebral infarction that preceded acute exacerbation of ITP. An 80-year-old woman with a history of ITP presented with tetraplegia, and brain magnetic resonance imaging revealed multiple infarction in bilateral cerebral and cerebellar hemispheres. For ITP, she was treated with oral prednisolone and subcutaneous injection of thrombopoietin receptor agonists. Her platelet count was within the normal range at the onset of cerebral infarction. Medical work-up did not reveal the obvious causes of her multiple cerebral infarction. On day 10 of hospitalization, she showed melena and oral hemorrhage and her platelet count markedly decreased. Her platelet-associated IgG level was elevated and a diagnosis of acute exacerbation of ITP was made. She was treated with intravenous immunoglobulin and her platelet count increased moderately. However, her neurological symptoms and cerebral infarction on magnetic resonance imaging deteriorated accompanied by hemorrhagic transformation. Finally, she died of respiratory failure. CONCLUSIONS: Our case suggests that thrombophilia accompanied by ITP can precede actual exacerbation of ITP and we have to consider ITP as a possible cause of multiple cerebral infarction, even when the platelet count is within the normal range at the onset of cerebral infarction.

[Characterization and pathophysiological changes of cerebral infarction rat model with qi-deficiency and blood-stasis Syndrome].

This study aimed to observe the general state and changes in pathophysiological indexes of multiple cerebral infarction rat model with Qi-deficienty and Blood-stasis syndrome. Rats were randomly divided into 4 groups(with 30 in each group): the normal group, the sham group, the model group and the Yiqi Huoxue recipe group. Rats in the model group and Yiqi Huoxue group were provided with interruptable sleep deprivation for 7 days before the multiple cerebral infarction operation, and followed by another 4 weeks of sleep deprivation; rats in the Yiqi Huoxue group were intragastrically administrated with drug at a dose of 26 g·kg⁻¹, once a day for 4 weeks. The general state was observed, and the pathophysiological indexes were measured at 48 h, 2 weeks and 4 weeks after administration. The results showed that rats in the normal group and the sham group represented a good general state and behaviors, with a normal morphological structure of brain tissues; rats in the model group featured yellow fur, depression, accidie, loose stools and movement disorder, with obvious brain histomorphological damage, which became aggravated with the increase of modeling time; rats in the Yiqi Huoxue group showed release in the general state and above indexes. Compared with the sham group at three time points, rats in the model group showed decrease in body weight, exhaustive swimming time and RGB value of tongue surface image, and increase in whole blood viscosity of the shear rate under 5, 60 and 150 S⁻¹, reduction in cerebral cortex Na⁺-K⁺-ATPase, Ca²âº-ATPase activity and contents of 5-HT, rise in TXB2 levels and decline in 6-keto-PGF1a in serum(P<0.05, P<0.01). Compared with the model group, rats in the Yiqi Huoxue group showed alleviations in the above indexes at 2 w and 4 w(P<0.05, P<0.01). The results showed that the characterization and pathophysiological indexes in the multiple cerebral infarction rat model with Qi-deficiency and blood-stasis syndrome were deteriorated; Yiqi Huoxue recipe could significantly alliviate the abnormal conditions, which suggested of the model was stable and reliable and the pathophysiologic evolutionary mechanism might be related to energy metabolism dysfunction, vasoactive substance abnormality and changes in neurotransmitters.

Clinical and radiological differentiation between Trousseau syndrome and cardiogenic embolism: a retrospective case-control study.

Background: Trousseau syndrome (TS) is a thromboembolic event in cancer patients caused by abnormalities in coagulation and fibrinolytic mechanisms. Acute multiple cerebral infarction (AMCI) is a rare form of TS. This study aimed to discuss the differentiation of clinical and radiographic characteristics between TS and cardiogenic embolism (CE) with AMCI as the main manifestation. Methods: We retrospectively analyzed 69 patients with TS-AMCI and 105 patients with CE-AMCI who were treated at Shandong Provincial Hospital between August 2018 and October 2022. The clinical baseline data, laboratory indices, and imaging characteristics of the two groups were compared. A logistic regression was used to analyze the risk factors of TS-AMCI, and receiver operating characteristic (ROC) curves were used to analyze the predictive value of the risk factors. Results: In relation to the clinical data, there were statistically significant differences between the two groups of patients in terms of the lipid and coagulation indices. D-dimer [odds ratio (OR) =4.459, 95% confidence interval (CI): 1.871-10.625; P=0.001] and triglyceride (OR =6.001, 95% CI: 2.375-15.165; P<0.001) were independent risk factors for TS-AMCI. In relation to the radiographic characteristics, the infarctions in the TS-AMCI group were widely distributed in multiple arterial supply areas [23 (33.3%) vs. 10 (9.5%); P<0.001]. More importantly, bilateral anterior + posterior circulation was also an independent risk factor for TS-AMCI (OR =15.005, 95% CI: 1.757-128.17; P=0.013). Conclusions: Unexplained AMCI in the cancer-prone age group, abnormalities in the lipid and D-dimer levels, and infarction foci involving multiple arterial blood supply areas suggested a high probability of TS.

[A case of pneumococcal meningitis with reversible arterial stenosis].

A 72-year-old male was diagnosed pneumococcal meningitis and we started treatment with antibacterial drugs and corticosteroids. On the 6th day, his consciousness level decreased. On the 7th day DWI of MRI showed a new infarction in bilateral cerebellar, and MRA showed multiple arterial stenosis. On the 12th day, CT angiography showed expansion of cerebral infarction and progress of diffuse stenosis. After that the stenosis improved over time, it disappeared on the 39th day. These results suggest that vasospasm is involved in the pathology of vascular stenosis.

[A case of multiple cerebral hemorrhage caused by sudden increase of eosinophil in a patient with eosinophilic granulomatosis with polyangiitis].

A 42-year-old woman with bronchial asthma was admitted to our hospital due to sensory dominant mononeuritis multiplex lasting for more than 6 months. At that time, her eosinophil count was 761/µl and her sural nerve biopsy showed no findings suggestive of vasculitis. Four months later, she experienced sudden convulsions and right hemiparesis due to left lobular parietal subcortical hemorrhage, when her eosinophil count was elevated to 3,257/µl. Numerous microbleeds and small infarctions were also detected in the intracerebral areas of different regions with MRI. Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic necrotizing vasculitis of the small vessels, commonly affecting the peripheral nerves. Subarachnoid hemorrhage in patients with EGPA is extremely rare. Steep elevation of the eosinophil count may release certain cytokines, causing cerebral hemorrhage.

Analysis on value of CT and MRI clinical application in diagnosis of middle-aged patients with multiple cerebral infarction.

OBJECTIVE: To compare the application of MRI and CT imageological examination in diagnosis of middle-aged patients with multiple cerebral infarction. METHODS: 218 cases of patients with multiple cerebral infarction were selected for CT and MRI examinations, and the clinical value of CT and MRI examinations in diagnosis and imaging of middle-aged patients with multiple cerebral infarction was compared and analyzed. RESULTS: For the 218 cases of patients, the total detection rate of CT examination was 56.88% and that of MRI examination was 95.87%, indicating a statistically significant difference (x (2)=6.795, P=0.008). For the 85 patients in the group of less than 24 h, the detection rate of CT examination was 37.65% and that of MRI examination was 94.12%, and the comparative analysis between two groups suggested a statistically significant difference (x (2)=6.357, P=0.006); for the 70 cases in the group of 24~72 h, the detection rate of CT examination was 48.57%, and that of MRI examination was 97.14%, suggesting a statistically significant difference (x (2)=5.315, P=0.026); for the 63 cases in the group of greater than 72 h, the detection rate of CT and MRI examinations showed no statistically significant difference (P>0.05). This showed that the cerebral infarction detection rate of MRI examination was significantly higher than that of CT examination in the group of less than 24 h and the group of 24~72 h, while the difference in the cerebral infarction detection rate was not significant in the group of greater than 72 h. The number of lesions detected by MRI examination was significantly higher than that by CT examination (P<0.01); the capability of MRI examination to detect small lesions of cerebral infarction was significantly stronger than that of CT examination (P<0.05). CONCLUSION: MRI has significant advantages in diagnosis of middle-aged patients with multiple cerebral infarction when compared to CT.

Multiple cerebral infarction complicated with vascular Parkinsonism on cognitive function in patients / 公共卫生与预防医学

Objective To analyze the influence of patients with multiple cerebral infarction complicated with vascular Parkinsonism (VaP) on cognitive function, and to provide a theoretical basis for the diagnosis and treatment of patients with multiple cerebral infarction complicated with VaP. Methods A toatl of 206 patients with multiple cerebral infarction admitted to Ningde municipal hospital of ningde normal university from January 2020 to January 2022 were selected and divided into VaP group (n=58) and control group (n=148) according to whether they were complicated with VaP. Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of patients. The scale included 8 cognitive domains including attention and concentration, executive function, memory, language, visual structure skills, abstract thinking, calculation and orientation. Pearson was used to analyze the correlation between VaP and MoCA score in patients with multiple cerebral infarction. Age, sex, years of education, white matter disease, diabetes mellitus, coronary heart disease and other vascular risk factors were compared between the two groups. The independent risk factors for VaP in multiple cerebral infarction were analyzed by multiple linear regression. Results MoCA score in VaP group was significantly lower than that in control group (P<0.05). In terms of each item, scores of attention and concentration, memory, language and computation in VaP group were significantly lower than those in control group (P<0.05). Pearson correlation analysis showed that attention and concentration, memory, language and computational scores were correlated with VaP in patients with multiple cerebral infarction (r=-0.475, -0.314 , -0.302 , -0.389, P<0.05). There were statistically significant differences between the two groups in white matter lesions, lesion sites in left hemisphere and frontal lobe, diabetes mellitus and carotid artery plaque (P<0.05).White matter lesions (OR=2.571), diabetes mellitus (OR=2.369) and lesion location in the left hemisphere (OR=2.958) were independent risk factors for VaP in patients with multiple cerebral infarction (P<0.05). Conclusion The risk of VaP in multiple cerebral infarction is high, which is related to the cognitive function of patients. Early intervention such as brain function training should be given to patients with white matter lesions, diabetes and lesions in the left hemisphere. , can significantly improve patients' cognitive function and reduce the occurrence of VaP.
