Abstract

INTRODUCTION:

Signs in radiology are usually based on many common objects or patterns that are easily recognizable in everyday life. The objective behind this association is to aid in the understanding and diagnosis of the disease process. These signs can be seen in different imaging modalities such as plain radiograph and computed tomography.

PRESENTATION OF CASE:

4 consecutive cases of sigmoid volvulus presented at our tertiary hospital between January 2016 and June 2017. 2 of these cases were managed surgically and others were managed conservatively. The CT scan and abdominal radiographs in these patients were reviewed with consultant radiologist, which bear resemblance to the percussion instrument known as the steel pan.

DISCUSSION:

The literature has described few radiological signs of sigmoid volvulus in the past. In the following case series, we would like to introduce the "Steel pan Sign", a novel radiological pattern which bears a close resemblance to the percussion instrument known as the steel pan. The Steel pan sign is easier to recognize on CT scan of the abdomen. However, in some cases it can be seen on plain X-Rays.

CONCLUSION:

The appearance of sigmoid volvulus on CT scans as well as on plain abdominal X-rays bears a significant resemblance to the pattern observed on the face of the Trinidadian steel pan, the recognition of which can aid in the diagnosis of this disease.

KEYWORDS:
