Pituitary metastases, in contrast, are a rare condition, estimated as 1.8% of all resected sellar lesions. We present here a rare case of clear cell renal carcinoma metastasis to the pituitary gland. Case Report A 65-year-old patient with holocranial headache and diplopia, whose physical examination showed right eye abduction palsy and ipsilateral anisocoria. Magnetic resonance imaging (MRI) of the pituitary revealed a heterogeneous mass in T1 weighted imaging with mild peripheral contrast enhancement and considerable growth during follow-up. Prolactin levels were high and dropped to normal after use of cabergoline, but remained normal even after the medication was halted. Biopsy was compatible with clear cell renal carcinoma. After surgery, the patient underwent radiotherapy, which was effective in reducing the volume of the lesion. Discussion Only 25 cases of pituitary metastasis arising from the kidney were reported in the literature between the years of 1957 and 2018. Metastases can reach the pituitary through hematogenous spread, cerebrospinal fluid, and contiguous bony lesions. Clinical presentation varies from vague complaints such as fatigue or headache to more specific signs like polyuria and polydipsia, and ∼ 60% of cases have clinical manifestations. Conclusion Case reports of pituitary metastases are low worldwide, with only 25 case reports of kidney metastases in over a 60-year period. The rarity of the lesions and hormonal alterations due to pituitary stalk compression can mislead diagnosis, and some patients may even never be diagnosed regarding their lower life span. In this report, radiotherapy was effective postresection, and accounts for a treatment option. All these issues account for the relevance of these case reports.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chiari malformation (CM) and basilar impression (BI) are conditions usually associated with syringomyelia. Its prevalence has wide geographical variation, being higher in the Northeast of Brazil, making it relevant to study the subject in this region. Objective To analyze the frequency of signs, symptoms, and surgical aspects observed in patients undergoing decompressive treatment. Methods We performed a retrospective analysis of the medical records of patients diagnosed with syringomyelia who received decompressive surgical treatment in various hospitals in João Pessoa, Paraíba, between 1994 and 2021. Results Thirty patients were analyzed. Twenty-nine (96.7%) presented CM and 27 (90.0%) also presented BI. A wide variety of symptoms was found, with significant prevalence of muscle weakness, neck pain, and headache. Brevicollis, a finding considered typical of the Northeastern region and associated with craniocervical junction malformations, was present in 66.7%. The surgical technique used in 90% of patients was similar. Fourteen (46.7%) patients presented difficult craniocervical junction and 4 (13.3%) had occipital bone assimilation. Eighteen (60.0%) presented thickening of the arachnoid membrane. Postoperatively, there was clinical improvement in 21 patients (70%). Conclusions The sample majorly had CM and BI associated with syringomyelia. High prevalence of signs and symptoms related to the Brazilian northeastern phenotype was also found. Syringomyelia, therefore, has peculiarities in the population of the Northeast of Brazil that, when described, allow better understanding of the pathology in this group.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective To establish the usefulness of DC in patients with extensive ischemic stroke who came to the emergency room during the period between May 2018 and March 2019. Methods This was an analytical, prospective, and longitudinal study whose population corresponded to all patients with a diagnosis of extensive ischemic stroke. Results The sample consisted of 5 patients, of which 3 were female and 2 males, the average age was 62.2 years old (minimum 49 years old, maximum 77 years old). Of all the patients who underwent DC, it was found that 80% of the patients did not present an increase in intracranial pressure. Decompressive craniectomy was not performed in a case that responded adequately to medical treatment. The mean values of ICP were 25 mmHg with a minimum value of 20 mmHg and a maximum value of 25 mmHg; in patients with a moderate value, the ICP averages were < 20 mmHg. The mortality was of 40% (RANKIN of 6 points). Conclusions Decompressive craniectomy is useful in extensive ischemic stroke. The decision to implement DC in patients with extensive stroke rests on clinicoradiological parameters. The monitoring of the IPC was not particularly useful in the early detection of the neurological deterioration of the patients studied.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135825111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, invasive monitoring of intracranial pressure (ICP) is a very important tool in neurointensivism. However, there is controversy regarding ICP monitoring and prognosis. Objectives To evaluate whether there is a difference in mortality between patients with severe TBI who underwent invasive ICP monitoring compared with those who did not undergo such procedure. Methodology This is a unicentric study in the prospective cohort mode. A total of 316 patients with severe TBI were evaluated and, out of these 316 individuals, 35 were submitted to ICP monitoring. All clinical data were evaluated by the Tertiary Hospital Neurosurgery team in the city of São Paulo. Results Of the total cohort, 35 (11%) patients underwent ICP monitoring, while 281 did not. Comparing the 2 groups, there was no difference in terms of early mortality between patients who were submitted to monitoring and those who were not (34.3 versus 14.3%; p = 0.09); there was also no difference in terms of hospital mortality (40 versus 28.5%; p = 0.31) or intensive care unit (ICU) length of stay (16.10 days, 95% confidence interval [CI]: 10.6–21.6; versus 20.60 days, 95%CI: 13.50–27.70; p = 0.31).

However, the recovery of the autonomic function after treatment for CTS is rarely addressed in the literature, especially on the long-term. Case Presentation A 59-year-old lady sought treatment for a long-term history of numbness, tingling, and hand and arm pain. CTS was diagnosed by clinical and electrophysiological means. After 6 months of conservative treatment, surgical treatment was offered. Preoperative IRT was performed by static and dynamic evaluations immediately and 5 minutes after the cold challenge test using the FLIR C2 camera with accuracy of 2°C or 2%. Fingers were consistently colder (mean of 3.76°C), which clearly represented an autonomic dysfunction in the patient's hand. The patient underwent mini-open carpal tunnel decompression and did great postoperatively. One year after surgery, the patient was fully recovered and completely asymptomatic. IRT imaging showed a remarkable improvement of fingers temperature (mean of 3.36°C). Conclusions Our long-term results confirmed that functional recovery occurred concomitantly to autonomic recovery, which was demonstrated by consistent improvement in fingers' temperature.

In the present study, we review our experience, considering the technical issues, outcomes, and complications associated with the use of stereotactic intracavitary irradiation (SICI) with colloidal rhenium-186 (186Re) for cystic craniopharyngioma. Material and Methods The records of 33 patients with cystic craniopharyngiomas treated by SICI with colloidal 186Re were retrospectively reviewed. The median radiation dose to the cyst wall was of 408 Gy (range: 175 Gy to 500 Gy). All tumors were composed of a large cyst cavity, and 9 (27.3%) also had a solid component. The mean follow-up period was of 3.7 years. Results After SICI, 31 (93.9%) patients showed radiological evidence of cyst regression, and, in 2 (6.1%), no response was observed. An improvement in the visual deficits was observed in 8 cases (24.2%), and an improvement in endocrinogical disturbances, in 2 cases (6.1%). We observed complications in 3 patients (9.1%): diabetes insupidus in 1 case (3%), aggravation of visual acuity in 1 case (3%), and severe headache after infusion of the colloid in 1 case (3%); and 1 patient (3%) died after meningitis. Conclusion Stereotactic intracavitary irradiation with colloidal 186Re is a safe procedure, with satisfactory results in the present series, and should be considered, in the management of cystic craniopharyngiomas, the first-intention therapy or as an adjuvant to other therapeutical modalities, with acceptable morbidity and mortality rates.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
