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.

Warblers, gnatcatchers and wrens have slender, tweezerlike bills fit for plucking unsuspecting insects off leaves and tree branches with precision.

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 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.
Double Cervical Bird Beak Sign Resulting in Dysphagia
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.

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.

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.

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 .

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 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.

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.
