Ileal bronchogenic cyst: A case report and review of literature

Repeated misdiagnosis of small intestine bronchogenic cyst: a case report

Bronchogenic cysts are uncommon congenital malformations of the respiratory system. These cysts can be categorized as intrapulmonary, mediastinal, or ectopic. Ectopic bronchogenic cysts, which lack distinctive clinical and imaging features, are particularly challenging to diagnose. This study presents a 48-year-old woman having a small intestinal bronchogenic cyst. She was repeatedly misdiagnosed as having an ovarian chocolate cyst or a cystic mass of bladder origin three years ago. However, no cyst was found during the operation. Half a year prior to presenting at our hospital, the patient developed frequent urination, prompting her to seek further treatment. We eventually discovered a cyst in the small intestine. The histological evaluation of the specimen showed a bronchogenic cyst. Small intestine bronchogenic cysts are extremely rare and easily misdiagnosed. It should be considered as one of the differential diagnoses of pelvic cysts. Particularly, when intraoperative exploration of the pelvic cavity fails to detect any cysts, consideration should be given to the possibility of small intestine bronchogenic cysts.

Clinical and imaging characteristics of patients with bronchogenic cysts: a single-center retrospective analysis

BACKGROUND

Bronchogenic cysts (BCs) are rare and usually asymptomatic malformations detected during imaging examinations. We aimed to investigate the clinical and imaging characteristics of patients with BCs.

METHODS

We retrospectively evaluated patients who received surgery to remove their BCs from January 2015 to January 2019. Their baseline characteristics, clinical information, and imaging results were reviewed.

RESULTS

Our study included 129 patients, with 57 males and 72 females and a mean age of 42.7 years old. The most common location for BCs was the mediastinum (67 patients, 51.9%). Fewer than half of the patients (53 patients, 41.1%) reported clinical symptoms, with chest pain being the most common (16 patients, 30.2%). Neck BCs were more frequently observed in young patients (P = 0.002) and were more often associated with thyroid cancer (P = 0.007). A computed tomography scan was the most commonly used method to diagnose BCs in the lung and mediastinum, whereas ultrasound was the most commonly used diagnostic method for neck BCs. The characteristic images were well-defined, thin-wall cystic lesions in varying densities. A few lesions showed small, calcified spots along the rim or cavities.

CONCLUSIONS

Although most BCs were found in the mediastinum, their locations could vary in different sex and age groups. Particular attention should be paid to young patients with BCs in the neck to rule out thyroid cancer.

A 44-Year-Old Man With Chronic Lower Chest Pain

CASE PRESENTATION

A 44-year-old man was admitted to the hospital because of chest pain located around his lower thoracic spine with deep inspiration for 6 months. He denied having any cough, dyspnea, fever, or weight loss. He had no history of trauma. He was a nonsmoker, without any other personal or familial medical history. He had been examined at some hospitals, but the cause had not been determined.

Segmental Dilatation of Ileum Involving Bronchogenic Cyst in a Newborn

Objective: Congenital segmental intestinal dilatation (SID) and bronchogenic cyst in the abdomen are two uncommon and different pathologies. We report a bronchogenic cyst associated with segmental intestinal dilatation. Case: A 2-day-old 3300 g term infant developed bilious vomiting. A jejunoileal segment with a diameter of 10 cm was detected at surgery. Histologically, the wall musculature and enteric plexus of the segmentally enlarged small intestine stained normally for CD117 and negative for calretinin. A bronchogenic cyst of 3 cm in diameter was centered on the mesenteric border of the dilated intestine. Conclusion: SID has a normal staining pattern for CD117 (for interstitial cells of Cajal) and negative for calretinin. it would suggest that the innervation is defective, may be associated with a bronchogenic cyst in the newborn, causing obstruction, requiring surgery.

Abdominal bronchogenic cyst: A rare case report

BACKGROUND

Bronchogenic cysts are cystic masses caused by congenital abnormal development of the respiratory system, and usually occur in the pulmonary parenchyma or mediastinum.

CASE SUMMARY

A rare case of a bronchogenic cyst discovered in the abdominal cavity of a 35-year-old man is reported. Physical examination found a space-occupying lesion in the patient’s abdomen for 4 d. Laparoscopic exploration found the cyst tightly adhered to the stomach and its peripheral blood vessels; therefore, intraoperative laparotomy was performed. The cystic mass was resected en bloc with an Endo-GIA stapler. The final postoperative pathological diagnosis confirmed an abdominal bronchogenic cyst.

CONCLUSION

This is a rare case of a bronchogenic cyst that was discovered within the abdominal cavity of a male patient. The cyst is easily confused with or misdiagnosed as other lesions. Therefore, it is necessary to distinguish abdominal bronchogenic cyst from gastrointestinal stromal tumor, Meckel’s diverticulum, enteric duplication cyst, or lymphangioma. Although computer tomography and magnetic resonance imaging were the primary diagnostic approaches, endoscopic ultrasound-guided fine-needle aspiration could assist with clarification of the cytological or histopathological diagnosis before surgery.

Subdiaphragmatic bronchogenic cysts: Case series and literature review

Bronchogenic cysts are congenital malformations caused by aberrant foregut budding. They major occur in the thorax, with subdiaphragmatic cases being uncommon. Here, we present a series of 19 patients diagnosed with subdiaphragmatic bronchogenic cysts histopathologically at a single institution in China from 2012 to 2021. A literature review was also conducted by searching the PubMed database using keywords related to “bronchogenic cysts” and “subdiaphragmatic,” yielding 107 cases. Taken together, the 126 cases had a median age of 41.0 years (interquartile range, 30.0–51.0 years) and 62 of them were male (49.2%). The cysts were most commonly detected in the left adrenal region (36.2%), followed by the pancreatic region (11.5%) and gastric cardia/lesser curvature of the stomach (9.2%). All patients except two underwent surgery for a definite diagnosis, symptom alleviation, and (or) malignancy prevention. Most patients recovered fast and were discharged from the hospital within 1 week after surgery, and the surgical complications were infrequent. The prognosis was generally favorable, as no recurrence was reported during the follow-up as long as 77 months.

Bronchogenic cysts with infection in the chest wall skin of a 64-year-old asymptomatic patient: A case report

BACKGROUND

Skin bronchogenic cysts are extremely rare congenital bronchocystic changes caused by the abnormal development of the trachea, bronchial trees or lung buds during the embryonic period. The first case of skin bronchogenic cysts was reported in 1945. Since then, this disease has attracted increasing attention, but due to the low incidence, its pathogenesis is still not clear.

CASE SUMMARY

Here, we report another case of skin bronchogenic cysts with infection in a 64-year-old female patient. The patient had no symptoms for more than 60 years until her chest wall was recently found to be swollen, and she felt pain and discomfort. At the same time, secretions were found on the surface of the swelling. Color Doppler ultrasound examination showed abnormal echoes in the soft tissue under the frontal chest wall, suggesting the presence of cysts. Cytological puncture resulted in about 2 mL of pus and showed the presence of more acute inflammatory cells. The final clinical diagnosis was skin cyst with infection, and surgery was carried out. The pathological results obtained after surgery showed that the cystic wall was covered with column-like cilia epithelial cells, and the interstitial structure was partially inundated with inflammatory cells. After a variety of examinations and clinical diagnoses, we finally confirmed that the patient was suffering from bronchogenic cyst.

CONCLUSION

This article not only describes the case of an elderly patient with rare skin bronchogenic cysts with infection but also provides a detailed and correct diagnosis and a successful treatment process, which is of great value for the diagnosis and treatment of the disease.

Retroperitoneal Bronchogenic Cyst Located in the Presacral Space: A Case Report

Bronchogenic cysts are rare congenital anomalies that are most frequently found in the mediastinum along the tracheobronchial tree, especially in the posterior aspect of the superior mediastinum. Bronchogenic cysts have also been reported in intrapulmonary, intrapericardial, abdominal, and retroperitoneal locations. Herein, we report a case of a retroperitoneal bronchogenic cyst in the presacral space. The patient was diagnosed based on a post-operative histopathological examination.
