Omohyoid muscle syndrome (OMS) is one of the rare causes of lateral neck swelling during swallowing and it is often a worrisome observation due to the concern of malignancy and cosmetic deformity. Anatomical variation, congenital weakness, or trauma may cause incompetence of the fascial-retaining mechanism and subsequently OMS. Its prevalence is unknown as only a few cases were reported in the past and none in Malaysia. Diagnosing OMS is very challenging. Hence, imaging techniques like real time ultrasound or dynamic computed tomography can be useful in assessing the affected muscles.

Internal abdominal herniation can be a cause for bowel obstruction and still being under diagnosed. Transmesenteric internal herniation is increasing in occurrence as more surgical intervention being performed. Clinical diagnosis of internal herniation can be very challenging. Computed tomography could be the first imaging modality to discover a clinically unsuspected internal herniation especially in patient with previous surgical intervention. Radiologist should be aware of computed tomography features like reversal of the normal anatomical arrangement of the bowels as well as the mesenteric vessel changes, which raise the suspicion of internal hernia in patient presenting with bowel obstructive symptoms.
