However, incidence of calvarial TB is very low and it presents in varied forms posing a diagnostic dilemma and delay in management.\u0000 Objectives This article reports a case series of 15 patients with varied presentations of calvarial TB from a tertiary care superspeciality center of Haryana state in India.\u0000 Material and Methods Study is a retrospective analysis of 15 patients with calvarial TB treated between 2018 and 2021 in a tertiary care hospital. Clinical features, radiological findings, surgical and medical management, and outcomes were reviewed.\u0000 Results Of the 15 patients, 9 were males and age ranged between 12 and 45 years. Mean duration of symptoms was 2.9 months (range 1–5 months). The most common presenting symptoms were scalp swelling, discharging sinus, and pain. Four patients were treatment defaulters of pulmonary TB and two patients were found human immunodeficiency virus positive. Brain imaging showed peripherally enhancing extradural collection with bone erosions in most cases. Eleven patients were managed conservatively with fine-needle aspiration cytology (FNAC) or local debridement/sinus excision. Four patients were managed surgically with drainage of collection, excision of necrotic bone, followed by antitubercular therapy. One patient needed cerebrospinal fluid diversion for associated hydrocephalous with tubercular meningitis which could not recover and succumbed.\u0000 Conclusion Calvarial TB is a rare occurrence of common prevalent diseases. Conservative management with FNAC and sinus excision followed by antitubercular treatment are the mainstay of treatment. Surgery should be reserved for extensive lesion or lesion with mass effect.","PeriodicalId":94300,"journal":{"name":"Asian journal of neurosurgery","volume":"44 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141924204","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}

This study compares the impact of two FD stents with different effective metal surface area (EMSA) values on OA occlusion. <b>Materials and Methods</b> A numerical model of a 59-year-old female patient with a giant aneurysm in the left internal carotid artery and a jailed OA was created based on clinical data.

Most of these lesions are located in the thoracic and thoracolumbar regions. Magnetic resonance imaging is a valuable tool for understanding their location and provides important information regarding their origin and expansion. The aim of our study was to evaluate the demographics, presentations, surgical management, and outcome of a spinal arachnoid cyst. <b>Materials and Methods</b> All the patients from January 2003 to December 2021 who were symptomatic for spinal arachnoid cysts were taken for study. A retrospective analysis was performed. Radiological investigations were performed, and patients were graded according to the Nabors classification. Operative results were graded according to surgical technique. <b>Results</b> The study included 22 patients, 11 female and 11 male patients, with a male-to-female ratio of approximately 1:1. The mean age of presentation was 34.7 years (4-60 years). Of 22 patients, 15 have intradural arachnoid cysts, 7 have an intradural extramedullary arachnoid cyst, and 8 have an intramedullary arachnoid cyst. Symptoms varied from weakness in the lower limbs (50%), quadriparesis and spasticity (32%), bladder/bowel incontinence (14%), and pain (10%). Out of 22 patients, complete cyst excision was performed in 17 patients, marsupialization in 4 patients, and cystic-subarachnoid shunt in one patient. Weakness and spasticity gradually recovered over a period of time. At 1-year follow-up, all the patients had complete improvement in their weakness, spasticity, and bladder functions.
