Abstract
BACKGROUND Leiomyosarcoma (LMS) is a rare neoplasm that arises from tissues of embryonic mesodermal origin. Primary tissues of origin can include smooth muscle cells of the abdominopelvic viscera, blood vessels, or arrector pili muscles. LMS is known to metastasize to the lungs, with few reported cases of spread to the central nervous system. OBSERVATIONS A 66-year-old male with cutaneous LMS of the left forearm with metastases to the lungs and kidney that had been treated with chemoradiation presented with worsening headaches. Magnetic resonance imaging revealed a sellar lesion. An endocrine workup was unremarkable. Imaging over 6 months revealed rapid interval growth. Positron emission tomography demonstrated moderate uptake. Given the rapid growth, the patient was offered an endoscopic endonasal approach for resection. Pathology confirmed LMS. LESSONS To the authors' knowledge, this is the first documented case of LMS metastasis to the sella. Pituitary carcinoma or metastases to the sellar region should be in the differential among patients with sellar region tumors with a rapid growth rate, bony erosion, or findings of lesions in the upper cervical lymph nodes or soft tissue. Tumors that show significant interval growth should raise suspicion for nonadenomatous lesions, and surgical intervention should be considered even in the absence of endocrinological dysfunction or cranial neuropathies. https://thejns.org/doi/10.3171/CASE2435.

Giant primary intracranial multi-fossa leiomyosarcoma involving the frontal sinus, ethmoid air cells, anterior fossa, middle fossa, and intraventricular space: A case report and literature review. Surg Neurol Int 2023; 14:384. [PMID: 37941634 PMCID: PMC10629320 DOI: 10.25259/sni_647_2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 10/11/2023] [Indexed: 11/10/2023] Open
Abstract
Background Leiomyosarcomas (LMSs) is a type of sarcoma that arises from smooth muscle and generally presents in the abdomen. Although intracranial LMS has been identified before, most reported presentations have been in immunocompromised patients. Here, we present an intracranial LMS in an immunocompetent patient. Case Description A 22-year-old male with a history of an atypical pineal parenchymal tumor of intermediate differentiation resected by suboccipital craniotomy at the age of 12 followed by adjuvant radiation therapy, presented with 3 weeks of decreased appetite, weight loss, and lethargy. He subsequently underwent transbasal approach skull base tumor resection. Histologic examination of the mass along with the patient's history of radiation was supportive of a low-grade, radiation-induced LMS arising from the anterior fossa of the skull or meninges and extends to the frontal sinus and ethmoid air cells. Conclusion Primary intracranial LMS is an extremely rare diagnosis and presenting symptoms vary with the location and size of the tumor. Due to the poor specificity of clinical symptoms, diagnosis is often based on histology. The most common treatment is surgical resection. Adjuvant chemotherapy with various agents has been found to be somewhat effective outside the central nervous system. When LMS does occur, a history of immunocompromised state or previous radiation exposure is often present. Pathological confirmation is required for an appropriate diagnosis.

Abstract
Background Leiomyosarcoma is a highly malignant soft-tissue sarcoma with a poor prognosis. In recent years, treatment for leiomyosarcoma has not shown much progress. Primary intracranial leiomyosarcoma (PILMS) is a much rarer type of neoplasm, which occurs more frequently in immunocompromised patients. PILMS cases reported in the literature are scarce and treatment strategy and prognosis are still under debate. In this study, a case of PILMS secondary to the total resection of giant cell glioblastoma is reported. Case Description A 38-year-old male was hospitalized with a three-month history of a temporal opisthotic bump. His medical history included a total resection of a tumor located in the right temporal lobe performed 4 years earlier. Pathological examination led to a diagnosis of giant cell glioblastoma, and the patient underwent postoperative chemotherapy with temozolomide for 6 weeks plus simultaneous radiotherapy with 63.66 Gary. Four years later, during regular follow-up, a preoperative MRI brain scan resulted in a well-defined signal pointing out two nodule-like features located at the right temporal lobe and subcutaneous soft tissue, respectively, and near the area where the previous giant cell glioblastoma was located. The mass was completely removed by a transtemporal approach and postoperative pathology revealed that the mass was a leiomyosarcoma. The patient underwent postoperative radiotherapy and no recurrence occurred until now. Conclusions To date, research on soft-tissue sarcoma, especially PILMS, has not made much progress, and a limited number of studies have provided few details on the management of PILMS. The treatment of choice for PILMS is aggressive multimodal treatment based on total tumor resection and radiotherapy. Moreover, systemic treatment with chemotherapy and targeted therapy, such as olaratumab, as well as further research still needs to be performed as many questions are left unanswered. To our knowledge, this is the first report on a case of PILMS secondary to glioblastoma, which might serve as a potential reference for clinicians and clinical studies.

Abstract
Primary intracranial mesenchymal neoplasms are rare tumors. These tumors are usually metastatic disease from other primary sites. We presented a 31-year-old man with a 6-month history of gradually enlarging frontal mass and positional headache. There was no other symptom demonstrating other organs' involvement. The patient underwent an uncomplicated craniotomy with clear surgical margins. The pathology review and the immunohistochemistry staining confirmed leiomyosarcoma grade II. We prescribed radiation therapy with tumor dose of 60 Gy in 30 fractions with conformal treatment planning to the tumor bed. As this disease has a high potency for metastasis, we advised four courses of single agent doxorubicin chemotherapy 75 mg/m2 every 4 weeks starting one month after the end of radiotherapy. In the last follow-up visit 34 months later, the patient was disease free in physical exam and imaging findings.

Abstract
Primary intracranial leiomyosarcomas (PILMSs) are extremely rare neoplasms, and their management remains unclear. The authors aimed to enunciate the radiological features and design a treatment protocol based on previously published cases combined with our series. Clinical data from all 12 cases of PILMS treated at their institute between 2008 and 2018 were reviewed. Meanwhile, they searched the Ovid MEDLINE, Embase, PubMed, Web of Science and Cochrane databases using the keywords "leiomyosarcoma" and "intracranial," "central nervous system," "cerebral," or "brain" Previously published data were processed and used according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The authors' cohort included 4 males (33.3%) and 8 females (66.7%) ranging in age from 13 to 67 years with a mean of 44.1 ± 5.0 years. Gross total resection (GTR), subtotal resection, and partial resection were achieved in 8 (66.7%), 3 (25%), and 1 (8.3%) patient, respectively, and only four patients (33.3%) received adjuvant therapy after surgery. After a mean follow-up of 30.5 ± 7.6 months, 6 patients (50%) experienced recurrences, and all of them died at the final. Twenty-seven patients (15 were male and 12 were female), in the literature cases, were identified between January 1980 and November 2019, presenting with PILMS. GTR and non-GTR were achieved in 21 (77.8%) and 6 (22.2%) patients, respectively. Postoperative radiotherapy was administrated in 17 patients (63.0%), and postoperative chemotherapy was administrated in 9 patients (33.3%), After a mean follow-up of 22.2 ± 4.1 months, recurrence and death occurred in 8 (36.4%) and 4 (14.8%) cases, respectively. In the pooled cases, the univariate analysis model revealed that only GTR was a significantly favorable factor for increased progression-free survival (hazard ratio 0.270, 95% confidence interval = 0.093-0.787, p = 0.016) and overall survival (hazard ratio 0.255, 95% confidence interval = 0.073-0.890, p = 0.032). GTR was recommended as an optimal treatment; meanwhile, postoperative radiation was also a choice to help increase the survival of patients of PILMS.

Abstract
PURPOSE Epstein Barr virus (EBV)-associated smooth muscle tumors (SMT) in the central nervous system are rare tumors. EBV-associated SMT mainly occur in patient with compromised immune status. We report on a case of a HIV positive patient, who developed multiple EBV-SMTs, intracranially and in the spine. We systematically review the literature on the topic. CASE REPORT A 46 years old female with HIV was imaged for complaints of headaches for 2 years, when an intracranial lesion was found. The patient was followed with sequential MRI scans before an excision was performed 5 years later. Pathology revealed an EBV-associated SMT. Multiple other lesions appearing in the brain and in the spine over years were treated by stereotactic radiosurgery or by surgery. At the time of this report, the patient is alive under HARRT treatment without recurrence. METHODS A systematic PRISMA guided literature research was conducted on the topic reviewing multiple databases for EBV-associated SMT located in brain or spine. We identified 52 patients from the literature and performed a pooled analysis. RESULTS All patients in this cohort except one were immuno-suppressed from HIV, post-transplant therapy or because of CIS. Female predominance and a median age of 35 years was identified as was frequent multifocality. Therapeutic strategies varied but were mostly multidisciplinary with surgery. CONCLUSION Based on our results, EBV-associated SMT should be included in the differential diagnosis of intracranial lesions mimicking meningiomas in immuno-suppressed patients. Stereotactic radiosurgery can be offered as an alternate treatment option for suitable lesions. Long-term surveillance via MRI scanning is recommended for follow up.

Abstract
Primary leiomyosarcomas of the central nervous system are extremely rare tumors, with few cases reported in the literature. In this article we report the case of a patient with an intracranial leiomyosarcoma of the cavernous sinus. This is the case of a 23-year-old man with a history of human immunodeficiency virus (HIV) and Epstein-Barr virus infection, with clinical picture of headache and left palpebral ptosis, who underwent nuclear magnetic resonance imaging that showed a lesion that occupied the cavernous sinus. Excisional biopsy reported fusocellular mesenchymal neoplasm with smooth muscle differentiation by immunohistochemistry compatible with low-grade leiomyosarcoma. The patient was initially taken to a partial resection, without treatment. Subsequently, the patient presented progression of his disease, so the area of neurosurgery considered that the lesion was unresectable due to its location and the risk of sequelae. It was then decided to treat the patient with intensity-modulated radiation therapy technique external radiotherapy. At six months of treatment, the patient continues asymptomatic with a stable disease.

Abstract
RATIONALE Primary intracranial leiomyosarcoma (LMS) is an extremely rare tumor in the central nervous system (CNS), and usually seen in immunocompromised individuals. Only a few cases of primary intracranial LMS have been documented in the literature and no study focused on their MRI findings. We reported a case of primary intracranial leiomyosarcoma in a immunocompetent patient and review its imaging features. PATIENT CONCERNS A 20-year-old female was admitted to our hospital, complaining with nausea, weight loss and progressive headache in recent 2 years. DIAGNOSIS The magnetic resonance imaging scan of the brain revealed a large well-defined extra-cerebral mass adherent to left temporal meninges. The mass was iso-intense on T1-weighted images (T1WI), lightly iso to hypointense on T2-weighted images (T2WI) and enhanced uniformly with contrast medium. The preoperative diagnosis is meningioma. INTERVENTIONS A left craniotomy was performed for the complete resection of the mass. OUTCOMES The lesion was diagnosed via surgical histopathology and immunochemistry as leiomyosarcoma. No evidence of recurrence and complications were found in the following 13 months. LESSIONS Primary intracranial leiomyosarcoma which has some special MR imaging features should be considered in the differential diagnosis of intracranial tumor.

Abstract
Primary intracranial leiomyosarcoma (PIL) is a rare non-infectious aetiology of focal mass lesions among HIV-infected individuals. With only 16 published cases worldwide, information on its pathophysiology, risk factors, clinical course and management options is limited. We report two cases of PIL in HIV-infected Filipino men who presented with 1-3 months history of persistent headache, progressing in severity. Both had cranial MRI revealing intracranial mass diagnosed as leiomyosarcoma by excision biopsy and immunohistochemical staining. Both patients underwent adjuvant cranial radiotherapy and chemotherapy. Biologics were initiated in one patient. Both patients were alive with evidence of the disease.

Abstract
The increasing vital roles of long coding RNA (lncRNAs) in the glioma tumorigenesis have renewedly and roundly recognized. Nevertheless, the in-depth that lncRNAs modulate the gliomagenesis is still elusive. In this research, we focus on the functional study of lncRNA SNHG12 in the glioma pathogenesis. SNHG12 expression was enhanced and high-expressed in the glioma clinical tissue samples and cell lines, especially in the advanced clinical grade. In functional study, knockdown of SNHG12 impaired the proliferation, induced the apoptosis in vitro and, meanwhile, inhibited the tumor growth in vivo. In mechanistic study, it was found that SNHG12 harbored the complementary binding sites with miR-101-3p at 3'-UTR, acting as a miRNA 'sponge'. Furthermore, miR-101-3p also targeted the 3'-UTR of FOXP1 mRNA. The three elements construct the SNHG12/miR-101-3p/FOXP1 axis. Overall, we confirmed a functional regulatory pathway that SNHG12 and miR-101-3p regulated the expression of FOXP1 in glioma cells, forming the SNHG12/miR-101-3p/FOXP1 pathway. This finding might act as a valuable target for glioma.
