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.

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 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 appearance, although classically occurring in primary achalasia, can also occur in pseudoachalasia due to a gastric tumor involving the gastro-esophageal junction.
Aortic Dissection Radiology Reference Article RadioGyan
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.

Barium swallow showed the classic "bird beak" sign (Figure 2), and the high-resolution esophageal manometry (Figure 3) confirmed the diagnosis of type III esophageal achalasia based on the Chicago.

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.
(a) Barium oesophagram that shows dilatation and bird beak sign
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.
Achalasia with bird beak sign Radiology Case
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.
A case of sigmoid volvulus with classical bird's beak sign
Bird's beak sign. The "bird's beak" sign is a classic finding on esophagrams; it describes a dilated proximal esophagus with a smooth-tapered, distal esophagus at the level of the esophageal hiatus in the setting of achalasia. 1 The smooth tapering of the distal esophagus resembles the beak of a bird (Figure 1). On imaging and manometry.
Barium swallow showed "Bird beak sign" suggestive of achalasia
Warblers, gnatcatchers and wrens have slender, tweezerlike bills fit for plucking unsuspecting insects off leaves and tree branches with precision. Other species prefer hitting the bird equivalent of the drive-thru. Purple martins, nighthawks and flycatchers have wide, flattened beaks for catching insects in midair.

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 .
Double Cervical Bird Beak Sign Resulting in Dysphagia
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.
