    Abstract Background: Developmental meningoceles of the sphenoid sinus are uncommon. When encountered, they are often associated with cerebrospinal fluid (CSF) rhinorrhea.
    Observations: The authors present the case of a 27-year-old female with a large meningocele eroding through the sella turcica and sphenoid sinus into the nasopharynx. The patient presented with intractable headaches and amenorrhea without CSF rhinorrhea.
    Lessons: The patient underwent an endoscopic endonasal transsphenoidal reduction of the meningocele with reelevation of the pituitary gland and skull base reconstruction with abdominal fat graft and nasoseptal flap.

    Abstract Introduction and importance: Acute colonic pseudo-obstruction (ACPO) is an uncommon phenomenon that is especially rare in young patients and can result in bowl ischemia and perforation if left untreated. Furthermore, pneumoperitoneum is almost always a concerning imaging finding and in the context of recent colonic resection may be a sign of anastomotic leakage.
    Case presentation: We describe a case of a young female patient with postpartum ACPO who subsequently underwent a hemicolectomy with colorectal anastomosis. The patient's hospital course was complicated by massive postoperative pneumoperitoneum that resulted in resection of the anastomosis and creation of an end colostomy. However, despite this measure, there was recurrent pneumoperitoneum on cross-sectional imaging 36 h later. This was treated non-operatively and the remainder of their hospital course was uneventful.
    Clinical discussion: A potential etiology for ACPO during pregnancy may be due to compression of parasympathetic plexus nerves by the gravid uterus. Idiopathic pneumoperitoneum has been documented on a number of occasions, though this is generally in older patients. It can present with signs of peritonitis or can be asymptomatic. Simultaneous pneumothorax and pneumoperitoneum is rare and may be due to the transmission of air from the peritoneum to the mediastinum and thorax. The pneumoperitoneum itself may be due the air leakage through the significantly distended colon into the peritoneum.
    Conclusion: The combination of ACPO following pregnancy and associated pneumothorax, pneumomediastinum, and recurrent pneumoperitoneum suggest a communicating defect between the thoracic, mediastinal, and peritoneal cavities. Furthermore, the possibility of underlying colonic dysmotility should be considered prior to the restoration of large bowel continuity.

    Abstract Pseudoaneurysms of the middle meningeal artery are rare events following head trauma. Given the potential for significant morbidity and mortality associated with pseudoaneurysm rupture, it is recommended that they be treated early. Endovascular embolization is a viable alternative to open surgical intervention. Here, we describe a case of an incidentally found middle meningeal artery pseudoaneurysm in a patient with a carotid-cavernous fistula after head injury. The pseudoaneurysm was treated with endovascular coil embolization.

    Abstract Background: Imaging modalities with increased spatial resolution have allowed for more precise quantification of cerebral aneurysm shape in 3-dimensional (3D) space. We conducted a systematic review and meta-analysis to assess the correlation of individual 3D morphometric measures with cerebral aneurysm rupture status.
    Methods: Two independent reviewers performed a PRISMA (preferred reporting items of systematic reviews and meta-analysis)-guided literature search to identify articles reporting the association between 3D morphometric measures of intracranial aneurysms and rupture status.
    Results: A total of 15,122 articles were identified. After screening, 39 studies were included. We identified 17 3D morphometric measures, with 11 eligible for the meta-analysis. The meta-analysis showed a significant association with rupture status for the following measures: nonsphericity index (standardized mean difference [SMD], 0.66; 95% confidence interval [CI], 0.53-0.79; P < 0.0001; I
    Conclusions: Based on the results of a meta-analysis containing 39 studies, the nonsphericity index, undulation index, elongation, flatness, and sphericity demonstrated the most consistent correlation with rupture status.

    Abstract Objective: Although the role of inflammation in the development of aneurysms is established, less is known about the development of intracranial aneurysms in the setting of underlying autoimmune disease. The underlying systemic inflammatory characteristics of disorders such as systemic lupus erythematosus, rheumatoid arthritis, and Sjögren's syndrome may influence the development of intracranial aneurysms through common inflammatory pathways. The authors hypothesized that there is an association between underlying autoimmune disease and aneurysm growth and rupture.
    Methods: Medical records of patients who underwent cerebral angiography between August 2018 and August 2021 were manually reviewed. Autoimmune diseases as defined for this study are those known to have systemic inflammatory effects on the central nervous system or multiple other organ systems. Statistical analysis, including construction of multivariable linear and logistic regression models, was performed using R version 4.1.0.
    Results: Chart review identified 190 patients with 469 ruptured and unruptured saccular intracranial aneurysms. There were 31 patients with 44 aneurysms identified as having an autoimmune disease. The mean size of a ruptured aneurysm was significantly smaller among patients with autoimmune disease compared with patients without autoimmune disease (4.14 mm vs 5.34 mm, p = 0.03). The multivariate logistic regression model did not identify any significant association between rupture and autoimmune disease when controlling for other variables (p = 0.49). In the multivariate linear regression model, autoimmune disease was still significantly associated with a smaller size at rupture (p = 0.04), and smoking was associated with a larger size at rupture (p = 0.03) when controlling for other variables. A second multivariate logistic regression model found autoimmune disease to be independently associated with rupture at a size smaller than 7 mm (p = 0.02), while smoking was independently associated with rupture at a size larger than 7 mm (p = 0.01).
    Conclusions: Autoimmune disease is associated with a smaller aneurysm size at rupture, although it is not associated with rupture itself. This association may be due to inflammatory pathways that are common to autoimmune diseases as well as aneurysm wall development. Although the authors were unable to identify any association between rupture status and the presence of autoimmune disease, the association between smaller size at rupture and autoimmune disease warrants further studies, as autoimmune disease may influence the trajectory of aneurysm development and the decision to treat.
