Purpose: Subhepatic cecums are rare conditions (0.3-0.5% of live births) that result from a malrotation event during embryologic development. Although this condition is uncommon, it presents unique challenges for diagnosing appendicitis due to the appendix being displaced to the right upper quadrant instead of its typical right lower quadrant location.
Methods: An 85-year-old male cadaver with a medical history significant for type 2 diabetes mellitus, atrial fibrillation, systolic congestive heart failure, and severe protein malnutrition was used during routine dissections of the gastrointestinal system.
Results: A subhepatic cecum was identified with a vermiform appendix situated just below the liver. Further examination revealed a unique variation in the pathways of the ileocecal artery to accommodate the malrotation.
Conclusion: Despite being rare, understanding this developmental variation is beneficial for the accurate diagnosis and treatment of patients with unusual presentations of appendiceal and colonic pathologies.

Purpose: To report the first documented case of an enlarged hypoglossal branch of the ascending pharyngeal artery (APA) traversing the hypoglossal canal and continuing to the anterior inferior cerebellar artery (AICA).
Methods: Magnetic resonance imaging (MRI), including extracranial and intracranial magnetic resonance angiography (MRA), was performed for the evaluation of suspected cerebrovascular disease in a 58-year-old man presenting with acute-onset right hemianopsia. The examinations were performed using a 3-Tesla scanner, and intracranial MRA was performed using a standard 3-dimensional time-of-flight technique.
Results: MRA demonstrated an enlarged right APA entering the hypoglossal canal and continuing to the AICA. The right vertebral artery was hypoplastic and continued to the posterior inferior cerebellar artery.
Conclusion: We report the first documented case of continuity between the APA traversing the hypoglossal canal and the AICA. A meticulous review of MRA source images and the creation of maximum-intensity-projection and partial volume-rendering images are useful for the reliable recognition of this variation.

Variations in the hepatic arterial system, observed in up to 22% of the population, significantly influence the outcomes of hepatobiliary and pancreatic procedures. This study describes an extremely rare variant involving an aberrant right posterior hepatic artery (aRPHA) originating from the gastroduodenal artery (GDA) alongside a replaced left hepatic artery (LHA). Awareness of such variants is critical during pancreaticoduodenectomy to prevent ischemic complications.
