Case ReportsTorsion of an accessory spleen: Case report and review of the literature.
Torsion of an accessory spleen is an uncommon cause of abdominal pain. Only a few cases have been reported in the literature. Most cases occur in children, and in most cases the diagnosis is made at surgery. ⋯ The diagnosis was made on contrast-enhanced computed tomography (CT) and was confirmed at surgery. Without treatment, torsion of an accessory spleen can lead to hemorrhagic shock, peritonitis, and bowel obstruction. It is useful for the radiologist to make this diagnosis on imaging so that biopsy can be avoided and surgery performed to avoid complications.

Case ReportsAsymmetric sensorineural hearing loss caused by vestibular schwannoma: Characteristic imaging features before and after treatment with stereotactic radiosurgery.
We report the case of a 71-year-old man who presented with a 2-year history of progressive left-sided hearing loss caused by a cerebellopontine angle mass lesion with classic imaging characteristics of a vestibular schwannoma. Vestibular schwannomas are typically diagnosed on dedicated MRI of the internal auditory canals obtained for asymmetric sensorineural hearing loss, as in this case. We review the characteristic imaging features of vestibular schwannomas that enable their differentiation from other mass lesions of the cerebellopontine angle cistern, allowing for treatment with stereotactic radiosurgery in this case.

Case ReportsCerebellopontine angle meningioma presenting with hearing loss.
We present the case of a 48-year-old woman with a cerebellopontine angle meningioma who presented with sensorineural hearing loss. The lesion was nearly 4 cm in maximum dimension and extended into the internal auditory canal. Hearing loss resulting from cerebellopontine angle tumor is most commonly caused by vestibular schwannomas, which arise directly from the sheath of the vestibular nerve (VIII) in the internal auditory canal. Our case provides a review of magnetic resonance imaging features that aid in differentiation of enhancing cerebellopontine angle masses that can have similar clinical presentations.

Case ReportsThe Arcuate Sign: A Marker of Potential Knee Dislocation? A Report of Two Cases.
The arcuate sign is a well described finding of fibular head avulsion at the insertion site of the arcuate complex. It has been associated with posterolateral corner knee injury and resulting instability. The authors report two patients presenting with the arcuate sign following knee dislocation, which has not been previously described. As unrecognized spontaneously reduced knee dislocation often results in significant morbidity, the authors propose that the arcuate sign should raise clinical suspicion of this injury mechanism.

Case ReportsComputed Tomographic Detection of Toothpick Perforation of the Jejunum: Case Report and Review of the Literature.
Foreign body ingestion is commonly encountered in the emergency department. Although in most cases, the ingested object will pass uneventfully in the feces [1], ingestion of sharp foreign bodies such as dental plates, sewing needles, toothpicks, fish bones and chicken bones carries increased risk of gastrointestinal perforation [2, 3, 4]. The use of toothpicks as both tooth-clearing implements and eating utensils increase the likelihood of toothpick unintentional ingestion [5]. ⋯ These pointed wooden bodies when accidentally swallowed are associated with higher risk of complications, such as gastric, small bowel or colonic perforation, obstruction, colonic impaction, gastrointestinal bleeding, subphrenic abscess, fistula formation, sepsis and/or death due to the damaged caused by the sharp pointed ends [7, 8, 9]. Unfortunately, many patients who ingested such objects fail to remember the mis-swallowing event when symptoms of perforation develop, making diagnosis problematic. We present a case of jejunal perforation secondary to an ingested wooden toothpick correctly diagnosed with Computed Tomography (CT).
