Acute diverticulitis is a painful condition of the gastrointestinal tract that results from sudden inflammation of one or more diverticula in the bowel wall. Right-sided acute diverticulitis, such as cecal diverticulitis, is uncommon diagnosis that can be easily misdiagnosed as acute appendicitis as it shares similar clinical presentation. An unusual complication of right-sided acute diverticulitis such as perforated cecal diverticulitis has different management from acute appendicitis. Thus, definitive diagnosis of this clinical condition with imaging is crucial to optimal management. We report a case of 43-year-old man who presented to the Emergency Department with acute onset severe right lower quadrant abdominal pain associated with anorexia, fever, and nausea. Computed tomography scans obtained showed findings consistent with perforated diverticulitis limited to the cecum, and normal caliber appendix. Conservative medical treatment was decided based on localized imaging findings with excellent outcome.

Congenital absence of the internal carotid artery is a rare occurrence. Even more infrequent are cases where the patient has a bilateral absence of the internal carotid arteries. Reported is a case of a 52-year-old woman who presented with optic nerve neuropathy, and was incidentally discovered to have a congenital bilateral absence of her internal carotid arteries. During computed tomography angiography imaging looking for cerebral venous thrombosis, related to her preexisting condition of bilateral elevated optic discs and residual left optic neuropathy, the findings were made. The absence of the arteries is not always recognizably symptomatic, with most findings being incidental through imaging studies only. This is because collateral flow allows for sufficient cerebral circulation. However, this condition puts such patients at higher risk for conditions such as aneurysms and subsequently strokes where the collateral flow exists.

Ewing sarcoma of the cervical spine is a rare diagnosis. Early recognition and treatment of this condition improves survival. Reported is a case of a 20-year-old male patient who presented with increasing neck pain. Computed tomography and magnetic resonance imaging showed a mass with a primary differential diagnosis of Ewing sarcoma. As a result of mass effect and spinal cord compression, immediate medical intervention was deemed necessary to prevent neurologic deficits.
