Purpose: To describe a case of short common trunk of the occipital artery (OA) and ascending pharyngeal artery (APA) arising from the internal carotid artery (ICA).
Methods: A 36-year-old woman with a history of surgical resection of a right lateral ventricular meningioma and atheromatous plaque of the right ICA underwent cranial magnetic resonance (MR) imaging and MR angiography of the head and neck region with a 3-Tesla scanner.
Results: MR angiography of the neck region showed a small atheromatous plaque at the origin of the right ICA and an anomalous artery arising from the posteromedial aspect of the right ICA at the distal end of the carotid bulb.

Background Photoacoustic microscopy (PAM) can be used to detect strong absorption from endogenous and exogenous contrast material, making it promising for detailed structural and functional imaging of hepatic sinusoids, including dynamic visualization of permeability. Purpose To evaluate whether PAM-based quantitative parameters of liver function and integrity (lacunarity, blood oxygen saturation [Sao], and Evans blue [EB] permeability) are associated with histopathologic indexes of fibrosis in a mouse model. Materials and Methods Between October 2022 and July 2023, a total of 35 male C57BL/6 mice were included in this study and received intraperitoneal injection of carbon tetrachloride to establish mouse models of progressive liver fibrosis, with seven mice in each group.

Anastomotic leakage (AL) is a significant complication following rectal cancer surgery, adversely affecting both quality of life and oncological outcomes. Recent advancements in artificial intelligence (AI), particularly machine learning and deep learning, offer promising avenues for predicting and preventing AL. These technologies can analyze extensive clinical datasets to identify preoperative and perioperative risk factors such as malnutrition, body composition, and radiological features.

In this manuscript, I comment on the article by Pospisilova published in the recent issue of the journal, in which selective embolization was used to treat anorectal hemangioma, a rare disease causing lower gastrointestinal bleeding. Anorectal hemangioma can easily be mistaken; for example, the patient in this case was previously misdiagnosed with ulcerative colitis. Choosing the appropriate tests and understanding the typical manifestations of anorectal hemangioma under colonoscopy, computerized tomography, magnetic resonance imaging and other tests are beneficial for diagnosis.

A critical clinical consideration, in addition to other common risk factors predisposing individuals to idiopathic intracranial hypertension (IIH), involves the potential co-occurrence of increased intracranial pressure and elevated cerebrospinal fluid protein levels in the presence of underlying malignancies. Primary diffuse leptomeningeal melanomatosis, an exceptionally rare condition with few reported cases in the pediatric population, illustrates this scenario. Timely decision-making based on clinical suspicion to perform a biopsy and involving a skilled pathologist for accurate reporting are essential steps toward achieving a definitive diagnosis.
