A case of acute colonic pseudo-obstruction, sigmoid volvulus, and massive pneumoperitoneum in a young female patient.

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.

Spontaneous sphenoid sinus meningocele with associated amenorrhea and headache: illustrative case.

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.

Post-traumatic Middle Meningeal Artery Pseudoaneurysm Treated With Endovascular Coil Embolization.

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.

Association between underlying autoimmune disease and small aneurysm size at rupture.

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.
