RESUMEN
Introduction: Trends regarding the locations of hypertensive cerebral hemorrhages are unclear. To clarify hypertensive hemorrhage trends, we investigated intracerebral hemorrhages (ICHs) over an 18-year period, focusing on thalamic hemorrhages compared with other sites of hemorrhages. Methods: We reviewed the cases of patients hospitalized for hypertensive ICH in 2004-2021 at our hospital; 1,320 eligible patients were registered with a primary ICH/intraventricular hemorrhage. After exclusion criteria were applied, we retrospectively analyzed 1,026 hypertensive ICH cases. Results: The proportions of thalamic and subcortical hemorrhages increased over the 18-year period, whereas putaminal hemorrhage decreased. Multivariate logistic regression analyses revealed that for thalamic hemorrhage, ≥200 mmHg systolic blood pressure (p = 0.031), bleeding <15 mL (p = 0.001), and higher modified Rankin scale (mRS) score ≥ 4 at discharge (p = 0.006) were significant variables in the late period (2013-2021) versus the early period (2004-2012), whereas for putaminal hemorrhage, significant factors in the late period were triglyceride <150 mg/dL (p = 0.006) and mRS score ≥ 4 at discharge (p = 0.002). Among the features of the thalamic hemorrhages in the late period revealed by our group comparison with the putaminal and subcortical hemorrhages, the total and subcortical microbleeds were more notable in the thalamic hemorrhages than in the other two types of hemorrhage, whereas cerebellar microbleeds were more prominent when compared only with subcortical hemorrhages. Discussion: Our findings revealed an increasing trend for thalamic hypertensive hemorrhage and a decreasing trend for putaminal hemorrhage. The thalamic hemorrhage increase was observed in both young and older patients, regardless of gender. The main features of thalamic hemorrhage in the late period versus the early period were decrease in larger hemorrhage (≥15 mL) and an increase in cases with higher systolic blood pressure (at least partially involved a small number of untreated hypertensive patients who developed major bleeding). The total and subcortical microbleeds were more notable in the thalamic hemorrhages of the late period than in the putaminal and subcortical hemorrhages. These results may contribute to a better understanding of the recent trends of hypertensive ICHs and may help guide their appropriate treatments for this condition.
RESUMEN
Central post-stroke pain (CPSP) is a neuropathic pain syndrome that frequently occurs following cerebral stroke. The pathogenesis of CPSP is mainly due to thalamic injury caused by ischemia and hemorrhage. However, its underlying mechanism is far from clear. In the present study, a thalamic hemorrhage (TH) model was established in young male mice by microinjection of 0.075 U of type IV collagenase into the unilateral ventral posterior lateral nucleus and ventral posterior medial nucleus of the thalamus. We found that TH led to microglial pannexin (Panx)-1, a large-pore ion channel, opening within the thalamus accompanied with thalamic tissue injury, pain sensitivities, and neurological deficit, which were significantly prevented by either intraperitoneal injection of the Panx1 blocker carbenoxolone or intracerebroventricular perfusion of the inhibitory mimetic peptide 10Panx. However, inhibition of Panx1 has no additive effect on pain sensitivities upon pharmacological depletion of microglia. Mechanistically, we found that carbenoxolone alleviated TH-induced proinflammatory factors transcription, neuronal apoptosis, and neurite disassembly within the thalamus. In summary, we conclude that blocking of microglial Panx1 channels alleviates CPSP and neurological deficit through, at least in part, reducing neural damage mediated by the inflammatory response of thalamic microglia after TH. Targeting Panx1 might be a potential strategy in the treatment of CPSP.

@#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: Thalamic hemorrhage (TH) with hematoma extension into the brainstem can lead to poor outcomes. In this study, we discuss the feasibility of the endoscopic-assisted contralateral paramedian supracerebellar infratentorial (SCIT) approach as a therapeutic method for treating such patients. Case presentation: A patient suffered from a sudden loss of consciousness and right limb weakness, and a CT scan indicated TH with hematoma extension into the brainstem. She consented to undergo surgery by the endoscopic-assisted contralateral paramedian SCIT approach. Results: Now, the patient can open her eyes on her own and move her left arm in response to commands. Conclusion: The endoscopic-assisted contralateral paramedian SCIT approach may be a viable therapeutic method for treating TH patients with hematoma extension into the brainstem.
RESUMEN
Background Basal ganglia hemorrhage (BGH) is a severe neurologic condition associated with significant morbidity and mortality, and its optimal management remains a topic of debate. Our study assessed the surgical outcomes of BGH patients at the 3-month mark using the modified Rankin Scale (mRS). Methods This retrospective observational study was conducted over 10 years at an advanced neuro-specialty hospital in Eastern India, including patients who underwent decompressive craniotomy and hematoma evacuation. Variables were systematically coded and analyzed to evaluate the postoperative outcome with age (in years), preoperative motor (M) status, and hematoma volume. Results This study enrolled 2,989 patients with a mean age of 59.62 (standard deviation: 9.64) years, predominantly males ( n = 2,427; 81.2%). Hypertension (1,612 cases) and diabetes mellitus (1,202 cases) were the most common comorbidities. Common clinical presentations included ipsilateral weakness (1,920 cases) and/or altered mental status (1,670 cases). At the 3-month mark postsurgery, 2,129 cases (71.2%) had a favorable outcome based on mRS, while 389 cases (13.0%) had an unfavorable outcome. The regression equation showed that age was inversely related to the percentage of individuals achieving a favorable outcome. It also revealed that the preoperative motor score was positively correlated with favorable outcomes. Hematomas smaller than 60 mL had better outcomes, with 1,311 cases (69.1%) classified as good outcomes and 337 cases (17.8%) as bad outcomes. Fatal outcomes related to the illness were observed in 471 patients (15.8%) within the study population. Conclusion Surgery for BGH showed a substantial improvement in outcomes, particularly in patients with M5/M4 motor status. The preoperative motor score (M status) emerged as a crucial predictor of favorable neurological outcomes. Age and hematoma volume, however, were found to be nondefinitive factors in determining good outcomes.
RESUMEN
Central poststroke pain (CPSP) is a central neuropathic pain syndrome that occurs following a stroke and mainly manifests as pain and paresthesia in the body region corresponding to the brain injury area. At present, due to the lack of clinical attention given to CPSP, patients suffer from long-term pain that seriously affects their quality of life. Current literature indicates that microRNA (miR)-223 can impede inflammation and prevent collateral damage. The NLR family pyrin domain containing 3 (NLRP3) inflammasome induces IL-18 and IL-1ß secretion and maturation and participates in the inflammatory response. Previous evidence has confirmed that miR-223 can negatively regulate NLRP3 in the development of inflammatory responses. However, whether the miR-223 targeting of NLRP3 is involved in CPSP remains unclear. In the present study, the expression of miR-223 was detected by reverse transcription-quantitative PCR analysis. The expression levels of NLRP3, caspase-1, ASC, IL-18, IL-1ß, ERK1/2, p-ERK1/2 and GFAP were detected by western blot analysis. The results demonstrated that thalamic hemorrhagic stroke triggered by microinjection of collagenase â £ (Coll IV) into the ventral posterior lateral (VPL) nucleus results in pain hypersensitivity. miR-223 expression level were significantly reduced in the CPSP model. The expression levels of NLRP3, caspase-1, ASC, IL-18 and IL-1ß were significantly increased in the CPSP model. The expression level of GFAP was detected to determine astrocyte activation. The results demonstrated that astrocyte activation induced by Coll IV produced a CPSP model. The p-ERK1/2 expression level was demonstrated to be significantly increased in the CPSP model. The introduction of an miR-223 agomir significantly attenuated thalamic pain and significantly decreased the levels of NLRP3, caspase-1, ASC and proinflammatory cytokines (IL-18 and IL-1ß). Furthermore, introducing a miR-223 antagomir into the VPL nucleus of naïve mice mimicked thalamic pain and significantly increased the levels of NLRP3, caspase-1, ASC and proinflammatory cytokine levels (IL-18 and IL-1ß). These results indicated that miR-223 inhibited NLRP3 inflammasome activity (caspase-1, NLRP3 and ASC), which ameliorated thalamus hemorrhage-induced CPSP in mice via NLRP3 downregulation. In conclusion, these results may determine the mechanisms underlying CPSP and facilitate development of targeted therapy for CPSP.
RESUMEN
Neuropathic pain is often chronic and can persist after overt tissue damage heals, suggesting that its underlying mechanism involves the alteration of neuronal function. Such an alteration can be a direct consequence of nerve damage or a result of neuroplasticity secondary to the damage to tissues or to neurons. Recent studies have shown that neuroplasticity is linked to causing neuropathic pain in response to nerve damage, which may occur adjacent to or remotely from the site of injury. Furthermore, studies have revealed that neuroplasticity relevant to chronic pain is modulated by microglia, resident immune cells of the central nervous system (CNS). Microglia may directly contribute to synaptic remodeling and altering pain circuits, or indirectly contribute to neuroplasticity through property changes, including the secretion of growth factors. We herein highlight the mechanisms underlying neuroplasticity that occur in the somatosensory circuit of the spinal dorsal horn, thalamus, and cortex associated with chronic pain following injury to the peripheral nervous system (PNS) or CNS. We also discuss the dynamic functions of microglia in shaping neuroplasticity related to chronic pain. We suggest further understanding of post-injury ectopic plasticity in the somatosensory circuits may shed light on the differential mechanisms underlying nociceptive, neuropathic, and nociplastic-type pain. While one of the prominent roles played by microglia appears to be the modulation of post-injury neuroplasticity. Therefore, future molecular- or genetics-based studies that address microglia-mediated post-injury neuroplasticity may contribute to the development of novel therapies for chronic pain.
RESUMEN
To summarize and analyze the clinical efficacy and safety of neuroendoscopic surgery (NES) in the treatment of patients for severe thalamic hemorrhage with ventricle encroachment (THVE). Eighty-three patients with severe THVE were treated in the Neurosurgery Department of Anqing Hospital Affiliated to Anhui Medical University from July 2019 to August 2021. Our study was approved by the ethics committee. The patients were randomly divided into NES group and extraventricular drainage (EVD) group. The hospital stay, Glasgow coma scale (GCS) scores on the 1st and 14th days postoperatively, the incidence of intracranial infections, and the clearance of postoperative hematomas were compared and analyzed between the two groups. The patients had follow-up evaluations 6 months postoperatively. The prognosis was evaluated based on the activity of daily living (ADL) score. A head CT or MRI was obtained to determine whether there was hydrocephalus, cerebral infarction, or other related complications. Eighty-three patients were randomly divided into 41 cases of NES group and 42 cases of EVD group. The length of postoperative hospital stay was 17.42 ± 1.53 days, the GCS scores were 6.56 ± 0.21, and 10.83 ± 0.36 on days 1 and 14, respectively; intracranial infections occurred in 3 patients (7.31%) and the hematoma clearance rate was 83.6 ± 5.18% in the NES group, all of which were significantly better than the EVD group (P < 0.05). After 6 months of follow-up, 28 patients (68.29%) had a good prognosis, 5 patients (12.19%) died, and 4 patients (9.75%) had hydrocephalus in the NES group. In the EVD group, the prognosis was good in 15 patients (35.71%), 12 patients (28.57%) died, and 17 patients (40.47%) had hydrocephalus. The prognosis, mortality rate, and incidence of hydrocephalus in the NES group were significantly better than the EVD group (P < 0.05). Compared to traditional EVD, NES for severe THVE had a higher hematoma clearance rate, and fewer intracranial infections and patients with hydrocephalus, which together improve the clinical prognosis and is thus recommended for clinical use.

Neural plasticity compensates for the loss of motor function after stroke. However, whether neural plasticity occurs in the somatosensory pathways after stroke is unknown. We investigated the left-right somatosensory interaction in two hemorrhagic patients using a paired somatosensory evoked potentials (p-SEPs) recorded at CP3 and CP4, which was defined as an amplitude difference between the SEPs of paired median nerve stimulations to both sides and that of single stimulation to the affected side. Patient 1 (61-year-old, left thalamic hemorrhage) has a moderate motor impairment, severe sensory deficit, and complained of pain in the affected right upper limb. Patient 2 (72-year-old, right thalamic hemorrhage) had slight motor and sensory impairments with no complaints of pain. Single SEPs (s-SEPs) were obtained by stimulation of the right and left median nerves, respectively. For paired stimulations, 1 ms after the first stimulation to the non-affected side, followed by a second stimulation to the affected side. In patient 1, a s-SEP with stimulation to the non-affected side and a p-SEP were observed in CP4. However, a s-SEP was not observed in either hemisphere with stimulation to the affected side. On the other hand, in patient 2, a s-SEP in CP3 with stimulation to the non-affected side and in CP4 with stimulation to the affected side were observed; however, a p-SEP was not observed. In addition, to investigate the mechanism by which ipsilateral median nerve stimulation enhances contralateral p-SEP in patient 1, we compared the SEP averaged over the first 250 epochs with the SEP averaged over the second 250 epochs (total number of epochs recorded: 500). The results showed that in the patient 1, when the bilateral median nerve was stimulated continuously, the habituation did not occur and the response was larger than that of the s-SEP with unilateral median nerve stimulation. In the current case report, the damage to the thalamus may cause neuroplasticity in terms of the left-right interaction (e.g., left and right S1). The somatosensory input from the affected side may interfere with the habituation of the contralateral somatosensory system and conversely increase the response.
RESUMEN
Neonatal thalamic hemorrhage is a strong risk factor for developing encephalopathy with continuous spikes and waves during sleep (ECSWS), even when not accompanied by widespread cortical destruction. The efficacy and indication of resective epilepsy surgery in such patients has not yet been reported. A 4-year-old boy was diagnosed with ECSWS based on strong epileptiform activation during sleep and neurocognitive deterioration. He had a history of left thalamic hemorrhage related to a straight sinus thrombosis during the newborn period. He presented with daily absence seizures that were refractory to medical treatment. At age 5, he underwent intracranial electroencephalogram (EEG) recording using depth and subdural strip electrodes placed in the left thalamus and over bilateral cortex, respectively. Interictal and ictal epileptiform discharges were observed in the thalamus, always preceded by discharges in the left or right parietal lobe. Left hemispherotomy successfully normalized the EEG of his unaffected hemisphere and extinguished his seizures. This is the first case report documenting resective epilepsy surgery in a patient with ECSWS due to neonatal thalamic injury without widespread cerebral destruction. Based on intracranial EEG findings, his injured thalamus did not directly generate the EEG abnormalities or absence seizures on its own. Patients with ipsilateral neonatal thalamic injury and even mild lateralized cortical changes may be candidates for resective or disconnective surgery for ECSWS.
RESUMEN
Objective:To explore the effects of hematoma removal by neuroendoscopy or craniotomy on thalamic hemorrhage.Methods:Eighty-three patients with thalamic hemorrhage, admitted to our hospital from September 2016 to March 2019, were chosen in our study; 44 patients accepted hematoma removal by neuroendoscopy and 39 patients accepted hematoma removal by craniotomy under microscope. These patients were divided into severe type ( n=55) and mild type ( n=28) according to Glasgow coma scale scores at admission. The efficacy and safety of the two procedures were compared. Patients were followed up until one year after onset, and their recovery was assessed by Glasgow outcome scale (GOS). Results:As compared with those in the craniotomy group, patients in the neuroendoscopy group had significantly small volume of intraoperative blood loss ([284.90±31.74] mL vs. [45.70±6.94] mL), significantly shorter hospital stays ([18.40±2.75] d vs. [14.70±2.13] d), and statistically lower incidence of epilepsy (15.4% vs. 2.3%, P<0.05). In critical survived patients, the GOS scores in the endoscopic group were 4.99±0.48 until one year after onset, which were significantly higher than those in the craniotomy group (2.64±0.41, P<0.05). Conclusion:As compared with hematoma removal by craniotomy, that by neuroendoscopy has the advantages of minimal invasion, good visual field, and high efficiency in the treatment of thalamic hemorrhage.
RESUMEN
Arteriovenous malformation (AVM) fed by the artery of Percheron (AOP) is extremely rare, with only one case described in the literature to date. We herein present a case of a 43-year-old female with hemorrhagic thalamic AVM mainly supplied by the AOP, who subsequently underwent conservative management and recovered well except for mild right hemiparesis. This case highlights that the AOP is a rarely recognized but clinically significant entity and should be identified when dealing with AOP-associated neurovascular disorder as described.
RESUMEN
BACKGROUND: Although surgeries for intracerebral hemorrhage remain controversial, endoscopic surgery is considered a promising surgical treatment. The most fatal type of thalamic hemorrhage is the medial type, which is always combined with expansion of the hematoma into the third ventricle. The current endoscopic approach to this lesion involves injury to the mediodorsal nucleus of the thalamus (MDT). CASE DESCRIPTION: We report 5 cases of medial thalamic hemorrhage with third intraventricular involvement treated by an endoscopic-assisted translateral ventricular transchoroidal fissure approach. The preoperative average volume of the parenchymal hematomas was 9.63 mL, while the preoperative average volume of the intraventricular hematomas was 23.35 mL. The average surgical duration was 80.6 minutes. No intraoperative MDT incision was needed in any patient. The evacuation rates of parenchymal and intraventricular hematomas were 74.21%-98.84% and 85.89%-99.51%, respectively. Three months after the surgery, the average Glasgow Coma Scale scores improved to 13.8 from 7.2 preoperatively. No ventriculoperitoneal shunt was needed in any patient. CONCLUSIONS: The endoscopic-assisted translateral ventricular transchoroidal fissure approach is a safe and effective approach for evacuation of a medial thalamic hemorrhage with third intraventricular involvement. This approach allows parenchymal hematoma evacuation through the rupture of the third ventricle without incising the MDT in the lateral ventricle.

PURPOSE: Thalamic hemorrhage breaking into ventricles (THBIV) is a devastating disease with high morbidity and mortality rates. Endoscopic surgery (ES) may improve outcomes, although there is no consensus on its superiority. We investigated the efficacy and safety of ES and compared the outcomes of different management strategies by ES, hematoma puncture and drainage (HPD), and external ventricular drainage (EVD) in patients with THBIV. METHODS: We retrospectively analyzed patients with THBIV treated by ES, HPD, or EVD at our hospital from June 2015 to June 2018. Patients were categorized into anteromedial and posterolateral groups based on THBIV location, and then the two groups were further divided into ES, HPD, and EVD subgroups. Individualized surgical approach was adopted according to the location of the hematoma in the ES subgroups. Patient characteristics and surgical outcomes were investigated. RESULTS: We analyzed 211 consecutive patients. There were no significant differences in clinical characteristics or incidence of perioperative procedure-related complications (postoperative rebleeding and intracranial infection) in either anteromedial or posterolateral groups. Compared with other therapeutic methods, the ES subgroups had the highest hematoma evacuation rate, shortest drainage time, and lowest incidence of chronic ventricular dilatation (all p < 0.05). Among the three anteromedial subgroups, ES subgroup had the best clinical outcomes which was assessed by the modified Rankin Scale, followed by HPD and EVD subgroups (p < 0.01); while in the posterolateral subgroups, clinical outcomes in the ES and HPD subgroups were similar and better than that in the EVD subgroup (p = 0.037). CONCLUSION: Individualized surgical ES approach for removal of thalamic and ventricular hematomas is a minimally invasive, safe, and effective strategy for the treatment of THBIV with a thalamic hematoma volume of 10-30 mL.

The aim of the present study was to investigate the efficacy of endoscopic surgery via a Kocher point approach for intraventricular hemorrhage (IVH) caused by thalamic hemorrhage (TH), in comparison with external ventricular drainage (EVD). Between January 2016 and August 2017, a total of 40 patients with IVH caused by TH were enrolled. The patients were assigned to an EVD group and an endoscopic surgery group in a non-randomized manner. The pre-operative characteristics recorded included age, pre-operative Glasgow Coma Scale (GCS) score, hemorrhage volume, length of neuro-intensive care unit stay and Graeb score of IVH. Outcomes included the GCS score at 2 weeks after surgery, 30-day and 90-day mortality rates, modified Rankin scale at 6 months after ictus and ventriculo-peritoneal (VP) shunt rate. The baseline characteristics were not significantly different between the two groups. The VP shunt rate in the EVD group was significantly higher compared with that in the endoscopic surgery group (50.0 vs. 15.0%; P=0.02; odds ratio, 5.7). In conclusion, smartphone-assisted endoscopic surgery via Kocher's point is feasible and safe, and significantly reduces permanent shunt dependency for IVH caused by TH.
RESUMEN
OBJECTIVE: To test whether robot-assisted surgery can improve prognosis of small-volume thalamic hemorrhage and to provide a surgical basis for treatment of small-volume thalamic hemorrhage. METHODS: This retrospective study included patients with thalamic hemorrhage and hematoma volume of 5-15 mL treated from December 2015 to December 2018. Patients were divided into an operation group and a nonoperation group. General data, types of hematoma, incidence of complications, Scandinavian Stroke Scale score, and modified Rankin Scale score were recorded and analyzed. RESULTS: Retrospectively, 84 cases met inclusion criteria: 35 cases in operation group and 49 cases in nonoperation group. At 90 days after onset, mortality was 11.4% in the operation group and 4.1% in the nonoperation group (P > 0.05). The Scandinavian Stroke Scale score in the operation group (43.3 ± 8.5) was higher than in the nonoperation group (36.1 ± 10.0) (P < 0.05). The modified Rankin Scale score in the operation group (2.9 ± 0.3) was lower than in the nonoperation group (3.7 ± 0.2) (P < 0.05). The incidence of pneumonia (8.6%) and renal dysfunction (14.3%) was lower in the operation group than in the nonoperation group (28.6% and 34.7%, respectively) (P < 0.05). There was no significant difference between the 2 groups in the incidence of central fever (5.7% vs. 12.2%), stress ulcer (11.4% vs. 16.3%), and ion balance disturbance (20.0% vs. 26.5%) (P > 0.05). CONCLUSIONS: Robot-assisted drainage of thalamic hemorrhage can improve prognosis and reduce the incidence of pneumonia and renal dysfunction.

Paroxysmal sympathetic hyperactivity (PSH) is a clinical condition characterized by abnormal paroxysmal surges in sympathetic nervous system activity. PSH is known to occur after severe head injury and hypoxic encephalopathy. Cases of PSH that develop after stroke have been reported worldwide; however, PSH is not commonly reported in the field of stroke research in Japan. Some studies have suggested that gabapentin may improve the symptoms of PSH. To our knowledge, this is the first case report demonstrating the efficacy of trazodone for the treatment of PSH that developed after thalamic hemorrhage. A 45-year-old woman presented to our clinic with headache and paralysis of the left side of her body after experiencing right thalamic hemorrhage; a conservative treatment was initiated at our hospital. Immediately upon hospitalization, she developed high fever, tachycardia, tachypnea, constipation, and overactive bladder and had breathing difficulties. Blood sampling revealed elevated levels of myocardial escape enzymes; however, coronary angiography did not show any significant stenosis or occlusion. The patient's symptoms improved after the administration of trazodone. She was diagnosed with catecholamine cardiomyopathy associated with PSH after intracranial hemorrhage and was subsequently transferred to a recovery and rehabilitation hospital unit where the oral administration of trazodone continued. Prolonged PSH contributes significantly to the impairment of daily activities in patients with stroke; therefore, early diagnosis and treatment are critical. Here, we report on the efficacy of trazodone as an effective treatment option for improving clinical outcomes and reducing the stay in the stroke care unit.

Cerebral sinovenous thrombosis (CSVT) is a focal or diffuse disruption of cerebral blood flow secondary to occlusion of cerebral veins and/or sinuses. The challenge of CSVT during the neonatal age has led to a great interest in this condition among neonatologists, child neurologists, and pediatric neuroradiologists. The highly variable clinical spectra, etiologies, and prognosis require fine medical skills and a high level of suspicion. Nevertheless, the diagnosis is often delayed or missed altogether. Differences in brain vulnerability at different stages of maturation may explain the spectrum of associated brain lesions, which varies with gestational age. Treatment is controversial and reported clinical outcomes vary widely. The controversial treatment of CSVT with anticoagulant therapy is based only on case series and expert consensus, there is lack of safety data.

BACKGROUND: Brain tumor are a major etiology of secondary intracranial hemorrhage (ICH) because ICH in patients with cancer often occurs from an intratumoral hemorrhage. However, it is sometimes difficult to detect a tumor when it is tiny and buried, especially during initial examination. CASE DESCRIPTION: A 65-year-old woman who was diagnosed with pulmonary small cell carcinoma 6 months previously developed sudden-onset consciousness disturbance and left hemiparesis. Head computed tomography (CT) showed a round, high-density lesion with a diameter of 31 mm in the right thalamus. There was no enhancement with administration of contrast agent.
