Killian-Jamieson diverticulum: real-time sonographic findings

Diagnosis of bilateral pharyngoesophageal diverticula with using swallow contrast-enhanced ultrasound: a case report

Pharyngoesophageal diverticulum (PED) is a rare disease of the esophagus that is usually asymptomatic and often found incidentally during a thyroid ultrasound examination. Due to its anatomical location close to the thyroid, it is easily misdiagnosed as a thyroid nodule, which leads to unnecessary thyroid biopsies and surgical treatment. The occurrence of a single esophageal diverticula is common, while the existence of multiple diverticula is rare. Left side diverticula are more common than right sided ones, while bilateral occurrences are rarely reported. We report an extremely rare case of bilateral pharyngeal esophageal diverticula. The patient was a 55-year-old asymptomatic man who came to our hospital after thyroid nodules were identified in another hospital. Due to the extensive clinical experience of the ultrasound physician at our facility, the patient was suspected to have bilateral esophageal diverticula, which was confirmed by using swallow contrast-enhanced ultrasound (CEUS). Consequently, unnecessary thyroid treatments were avoided in this patient. This study shows that although bilateral pharyngeal diverticula are unusual, the possibility of their existence should be considered if nodules are located posterior to the bilateral thyroid glands and have suspicious imaging characteristics. Particular attention should be given to nodules located on the right side of the thyroid, which are sometimes overlooked easily due to their very low incidence. If real-time ultrasound cannot be used in making the diagnosis, PED can be further identified using swallowing CEUS to avoid unnecessary thyroid fine needle aspiration (FNA) and surgical treatment.

Ultrasonographic characteristics of Killian-Jamieson diverticula

PURPOSE

A Killian-Jamieson diverticulum (KJD) may be mistaken for a thyroid nodule on ultrasound (US). The purpose of this retrospective study was to search for specific US features that would help differentiate between KJD and thyroid nodules.

METHODS

A total of 12 patients with KJD who had undergone an US examination of the neck were identified. The size, shape, boundary, echopattern, location, color flow signals on color Doppler US of KJD and the relationship between the lesion and esophageal wall were analyzed. The change of size, shape and internal echotexture were also observed when the lesion was compressed with the probe and when the patient was asked to drink water.

RESULTS

All KJD were confirmed by barium esophagography. All KJD were posterior to the left thyroid lobe on US, and were associated with a semicircular hypoechoic anterior wall. The internal echotexture was heterogeneous. In eight cases, the connection to the esophageal wall was seen. When compressing with the US probe or when the patients swallowed water, the size, shape or internal echotexture of the lesion changed.

CONCLUSION

The specific criteria for US diagnosis of KJD included the connection to the esophageal wall and the fact that the internal echotexture, shape and size of KJD changed in real-time when the patient swallowed water or when the lesion was compressed with the transducer.

Presentation and Management of Killian Jamieson Diverticulum: A Comprehensive Literature Review

Objective:

To examine the clinical presentation, diagnostic evaluation, and management of Killian–Jamieson diverticula (KJD) through literature review.

Methods:

A comprehensive literature review was conducted through December 2018 using keywords Killian–Jamieson diverticula/diverticulum. Data extracted included clinical presentation, imaging characteristics, surgical management, and postoperative care.

Sources:

PubMed and Google Scholar.

Results:

Sixty-eight cases of KJD in 59 reports (29M:39F; median 58 years old) were identified for review. The most common presentation was dysphagia (n = 39), suspected thyroid nodule (n = 24) and globus (n = 14). The majority of KJD (n = 51) occur on the left, with rare reports of right side (n = 11) and bilateral (n = 5) presentation. Thirty-two cases describe surgical management: 22 utilizing a transcervical approach, with (n = 13) or without (n = 9) cricopharyngeal myotomy; and 10 reported endoscopic surgery. Diverticula managed transcervically averaged 3.8 cm in size in comparison to average 2.8 cm in the endoscopic group. Time to diet initiation after transcervical surgery averaged 4 days versus 2 days after endoscopic surgery. Complications were reported in 2/68 cases; both were diverticula recurrence after endoscopic surgery.

Conclusion:

Killian–Jamieson diverticula is a rare diagnosis that should be considered in the evaluation of dysphagia, globus, and also suspected thyroid nodule. When patient symptoms warrant intervention, a transcervical approach, with or without cricopharyngeal myotomy, is most commonly utilized. In recent years, an endoscopic approach has been presented as an alternative for smaller diverticula. Further understanding of the optimal treatment and postoperative management for KJD requires larger cohorts.

Killian-Jamieson diverticulum mimicking a thyroid nodule: A case report

Killian-Jamieson diverticulum (KJD) is a rare disease of the cervical esophagus, often misidentified as thyroid nodules on ultrasonography. We performed carotid artery ultrasonography for an asymptomatic 68-year-old man. The ultrasound showed an oval nodule with heterogeneous echogenicity surrounded by a multilayered rim in the posterior left thyroid gland. As endoscopy and computed tomography confirmed pharyngoesophageal diverticulum in the anterolateral wall of the esophagus, we reached a final diagnosis of KJD. In cases where a thyroid nodule is detected by ultrasound, physicians should be aware of the possibility of KJD before performing invasive procedures.

Pharyngoesophageal diverticula simulating thyroid nodules: An unusual occurrence with unique features

Pharyngoesophageal diverticula (PED) of the Zenker's and Killian-Jamieson types arise in close proximity to the thyroid gland, and may rarely be confused with a thyroid nodule on ultrasonography. In this brief report, we detail the cytologic, clinical, and radiologic findings of three PED that were thought to be thyroid nodules, and were subjected to fine-needle aspiration (FNA). The patients were females with an age range of 51-64 years. All three patients had multiple thyroid nodules, and two patients reported symptoms attributable to the diverticulum. Nodule sizes ranged from 1.0 to 2.7 cm, and either the right or left thyroid lobe could be involved. Microcalcifications were present by ultrasonography in all three cases. FNA of these thyroid nodule mimics showed squamous cells with granular or amorphous debris, bacterial and/or fungal colonies, inflammation, and food particles. These cytologic features, particularly the presence of vegetable or meat fragments, are characteristic, and have also been reported in the few previous reports of PED. The presence of a diverticulum was confirmed with imaging studies in all our patients. Although a rare occurrence, the inadvertent FNA of a PED masquerading as a thyroid nodule is important to recognize, as a recommendation for appropriate radiologic studies could potentially avoid inappropriate therapy for thyroid disease.
