ABSTRACT
@#Contrast Enhanced CT Abdomen is usually used to investigate the source of the small bowel obstruction. A 13-year old girl presented with signs of small bowel obstruction and was complicated with acute renal injury. Non-contrast CT Abdomen showed findings consistent with bezoar, and the findings are similar to the features seen in a contrast study. This case shows that both the plain and the contrast CT abdomen give similar findings of bezoar, one not inferior to the other.
ABSTRACT
Fisherman`s Waders sign is caused by several medical conditions including venous thrombosis, portal hypertension and lymphoma. It is characterized by increased uptake of radiotracer in soft tissues below the mid-thorax level with normal tracer clearance above that level in bone scan. This case reports the Fisherman`s Waders sign in a patient with lymphoma complicated by Inferior Vena Cava (IVC) obstruction by the aid of CT scan and bone scan. Also, literature review of this rare sign is performed in this report. This sign can be found incidentally on bone scan and high level of awareness by the nuclear medicine physicians may alert the treating team for the underlying diagnosis.
ABSTRACT
Colorectal carcinoma is a common lethal disease with signs and symptoms that may be nonspecific. Computed tomography (CT) of the abdomen and pelvis with or without contrast is frequently performed for various general abdominal complaints, but unlike CT colonography, the large bowel may not be optimally prepared for evaluation. As such, careful and diligent assessment of the non-prepared colon in all CT images of the abdomen and pelvis is important, as it ensures that incidental colorectal malignancy is not missed, especially in older patients. This article gives an overview of multidetector CT imaging signs and subtle clues to aid in the diagnosis of colorectal carcinoma, as well as their pitfalls.
