The kidney bean sign (more commonly called the coffee bean sign; also bent inner tube sign) is a radiologic sign observed on abdominal radiographs that indicates the presence of a sigmoid volvulus, a form of bowel obstruction. It is seen as an area of hyperlucency resembling a coffee bean. [1]
Histologically, there are nests of transitional epithelial cells with longitudinal nuclear grooves (coffee bean nuclei) lying in abundant fibrous stroma. The coffee bean nuclei are the nuclear grooves exceptionally pathognomonic to the sex cord stromal tumour, the ovarian granulosa cell tumour, with the fluid-filled spaces Call–Exner bodies ...

After taking a thorough history, the diagnosis of colonic volvulus is usually easily included in the differential diagnosis. Abdominal plain x-rays are commonly confirmatory for a volvulus, especially if a coffee bean sign is seen. These refer to the shape of the air-filled closed loop of colon which forms the volvulus.
Sigmoid colon volvulus, also known as sigmoid volvulus, is volvulus affecting the sigmoid colon.It is a common cause of bowel obstruction [1] and constipation.It is common in Asia, India (7% of intestinal obstruction) and especially South India because of the high fibre diet.
For example, tumor markers like Ki-67 can be used to choose form of treatment or in prognostics but are not useful to give a diagnosis, while other tumor markers have the opposite functionality. Therefore it's important to follow the guidelines of the specific tumor marker. Tumor markers are mainly used in clinical medicine to support a ...
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. [1] Computed tomography provides an overall better surgical strategy planning, and possibly fewer unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. [2]
