A case of sigmoid volvulus with classical bird's beak sign
Transesophageal echocardiography showed a large thrombus in left atrial appendage (type Ib) protruding to the left atrium (LA). The thrombus had an echolucent centre giving appearance of bird's beak ('Bird-beak sign'; figure 1, see online supplementary video 1).

This sign can be distinguished from other described bird's beak signs as previously mentioned, and can possibly be diagnostic of achalasia for resource poor settings. The cost of an upper GI endoscopic study and conventional manometry ranges between $600-$700 USD, and this facility is not available in our public setting, versus a barium.

The hummingbird sign, also known as the penguin sign, refers to the appearance of the brainstem in patients with progressive supranuclear palsy (PSP) . The atrophy of the midbrain results in a profile of the brainstem (in the sagittal plane) in which the preserved pons forms the body of the bird, and the atrophic midbrain the head, with beak.

Bird's beak sign of the sigmoid is one of the signs of sigmoid volvulus. It represents gradual narrowing/tapering of the sigmoid colon up to the level of obstruction during contrast/barium insertion to the rectum or on CT. When located in the sigmoid colon, it suggests the diagnosis of sigmoid volvulus. If the obstruction is complete, no.
Barium swallow showed "Bird beak sign" suggestive of achalasia
Laboratory results were within normal limits. A plain radiograph of the abdomen revealed a "coffee bean" sign. We also observed an impressive picture of a typical "whirl" sign and a "bird's beak" sign on an emergent abdominal computed tomography (CT) scan. Also, his CT scan revealed marked distension and a twisted loop of sigmoid colon.

The esophageal bird's beak sign. Achalasia is an esophageal motility disorder characterized by abnormally decreased relaxation of the lower esophageal sphincter and decreased esophageal peristalsis [ 1 - 3 ]. While there is some uncertainty as to the role of the myenteric plexus ganglion cells in the pathogenesis of this condition.

The bird's beak sign of the esophagus is used to refer to the tapering of the inferior esophagus in achalasia. The same appearance is also referred to as the rat's tail sign.

The thrombus had an echolucent centre giving appearance of bird's beak ('Bird-beak sign'; figure 1, see online supplementary video 1). The patient was started on aggressive anticoagulation, rate control and diuretic therapy. After 2 months the patient underwent successful PTMC. Open in a separate window.

Case Discussion. The patient was suspected for sigmoid volvulus on x-ray (unfortunately, not available). Subsequently, Gastrografin enema was performed for therapeutic detorsion of the volvulus. However, therapeutic detorsion by Gastrografin enema was not achieved and the patient underwent sigmoidoscopy which finally relieved the volvulus.

This bird beak sign, originally applied to the appearance of sigmoid volvulus on conventional radiographs, can also be appreciated on axial CT images of the loop-type cecal volvulus. A specific CT sign for volvulus is the whirl sign , which has been described in volvulus of the midgut, cecum, and sigmoid colon 3 .

The inner bones of the bill do not grow as the bird ages, although the rhamphotheca grows continuously throughout the bird's life and is worn down through use. Sometimes, this causes the bills of caged birds to grow unusually long, but fortunately, experienced vets can trim the beak back into shape. In nature, constant regeneration helps.

The bird's beak sign metaphorically describes the fluoroscopic appearance of sigmoid volvulus. The sigmoid colon twists around its mesenteric axis, narrowing the lumen with resultant varying degrees of obstruction. On contrast enemas, the narrowed lumen just distal to the point of obstruction shows smooth tapering that resembles a bird's.
