“…In some cases, CCAM lesions gradually became smaller or even disappeared at the later stage of pregnancy[ 20 ]. More than 15% of CCAM lesions can disappear after birth[ 21 ]. In this study, postnatal CT found no lesions in five cases, macrocystic CCAM was confirmed in four cases, and microcystic CCAM was confirmed in one case, with a lesion disappearance rate of 16.1% (5/31).…”

BACKGROUND Congenital cystic adenomatoid malformation (CCAM) and bronchopulmonary sequestration (BPS) are the most common lung diseases in fetuses. There are differences in the prognosis and treatment of CCAM and BPS, and the clinical diagnosis and treatment plan is usually prepared prior to birth. Therefore, it is quite necessary to make a clear diagnosis before delivery. CCAM and BPS have similar imaging features, and the differentiation mainly relies on the difference in supply vessels. However, it is hard to distinguish them due to invisible supplying vessels on some images. AIM To explore the application value of magnetic resonance imaging (MRI) in the differential diagnosis of fetal CCAM and BPS. METHODS Data analysis for 32 fetuses with CCAM and 14 with BPS diagnosed by prenatal MRI at Huzhou Maternal and Child Health Care Hospital and Anhui Provincial Children’s Hospital from January 2017 to January 2020 was performed to observe the source blood vessels of lesions and their direction. Pathological confirmation was completed through CT examination and/or operations after birth. RESULTS After birth, 31 cases after birth were confirmed to be CCAM, and 15 were confirmed to be BPS. The CCAM group consisted of 21 macrocystic cases and 10 microcystic cases. In 18 cases, blood vessels were visible in lesions. Blood supply of the pulmonary artery could be traced in eight cases, and in 10 cases, only vessels running from the midline to the lateral down direction were observed. No lesions were found in four macrocystic cases and one microcystic case with CCAM through CT after birth; two were misdiagnosed by MRI, and three were misdiagnosed by prenatal ultrasonography. The BPS group consisted of 12 intralobar cases and three extralobar cases. Blood vessels were visible in lesions of nine cases, in four of which, the systemic circulation blood supply could be traced, and in five of which, only vessels running from the midline to the lateral up direction were observed. Three were misdiagnosed by MRI, and four were misdiagnosed by prenatal ultrasonography. CONCLUSION CCAM and BPS can be clearly diagnosed based on the origin of blood vessels, and correct diagnosis can be made according to the difference in the direction of the blood vessels, but it is hard distinguish microcystic CCAM and BPS without supplying vessels. In some CCAM cases, mainly the macrocystic ones, the lesions may disappear after birth.

“…In 1997, Stocker et al 14,15 classified CCAM into three types, type 1, 2, and 3, depending on the characteristics of the mass and source of the tissue. Type 1 originates from distal bronchus tissue or proximal bronchiole >2 cm in diameter and has multiple thin-wall cysts lined with a ciliated pseudostratified epithelium.…”

“…6 Then, in 2002, Stocker added two more types of CCAM classification: types 0 and 4. 14 Type 0 arises from tracheal or bronchus tissue, while type 4 arises from alveolar tissue. CCAM has the potential to develop into malignancy, especially in CCAM type 4.…”

“…Congenital cystic bronchiectasis is thought to be the result of developmental arrest. This may result in cyst formation, retention of fluid or air, and the risk of subsequent infection [1]. Congenital cystic bronchiectasis has been found almost exclusively in infants and young children [2,3] and also has been reported accompanying other congenital anomalies [4], or in patients with deficiency of bronchial cartilages.…”

Background and purpose: Congenital bronchiectasis (CB) is still an important problem for certain serious pulmonary infections. Surgical treatment of childhood CB has not been discussed extensively because of decline in prevalence and increased experience dealng with this disease. Although the incidence has declined over the past years in societies with high socioeconomic status, CB is still an important health problem in our country. This disease can be diffuse or focal. Diffuse CB is thought to occur owing to underlying systemic illness that causes abnormalities in airway clearance. For patients with bilateral disease, lung transplantation would be the only probable surgical approach. For patients with focal disease, conversely, the removal of the diseased lung had played the main role in the treatment of this disease. Recently, it has been shown that patients with an earlier and more localized disease can be successfully controlled by conservative approaches. It remains controversial as to which children would benefit from surgery and surgical points that may affect the outcome. Therefore, a retrospective study was conducted to evaluate the results of surgical treatment of CB in children. Patients and Methods: We retrospectively reviewed the medical records of 79 consecutive children who underwent surgery for CB in our clinic between 2006 and 2021. Patient demographics, clinical features, radiologic examinations, details of surgery including type of resection, operative morbidity, mortality and outcomes were analyxed. Results: Seventy-nine patients underwent 83 pulmonary resections during the study period. The mean ages at diagnosis of CB and at the time of surgery were 8.10 ± 4.10 years (range, 1 to 17 years) and 9.70 ± 4.20 years (range, 2 to 18 years), respectively. There were 44 males (55.7%) and 35 females (44.3%). The causes of bronchiectasis were congenital hypoplasy of bronchi (n = 31), secondary bronchiectasis was additional nonspecific pulmonary infection (n = 42) and foreign body aspiration (n = 6). Chest X-rays, bronchography and bronchoscopy (n = 79), chest HRCT (n = 61), angiopulmonography (n = 23) were used, and pulmonary function tests (n = 48) were performed. The types of resections were segmenectomy (26.5%), lobectomy (35.4%), and lobectomy with segmentectomy (17.8%), bilobectomy (8.9%) and pneumonectomy (11.4%). Four patients with bilateral bronchiectasis subsequently required second operation for the other lung. Two of those had undergone right lower lobectomy, by one child underwent right upper lobe, and another left lower lobectomies. One patient with incomplete resection subsequently required second operation for ongoing bronchiectasis underwent complementary right pneumonectomy. Morphological study (n=39) Postoperative complications were encountered in 6 patients (7.6%). In terms of long-term outcomes of treatment 78 (98.7%) patients were followed-up at least 6 months up to 14 years. The postoperative status of the patients as follows: “well” in - 49 patients (60.7%), “improved” in 23 patients (29.5%), “ orsened” in 6 patients (7.7%). And unfortunately two patients “died” (2.6%). Conclusions: The decision for bronchiectasis surgery should be made in cooperation with the chest diseases unit. Anatomic localization of the disease should be mapped clearly by radiologic and angiographic investigations. A radiologic and morphologic evidence of reversal of airway abnormality has been shown in cases of post-infectious bronchiectasis and congenital defects of bronchial wall. The morbidity and mortality rates of bronchiectasis surgery are within acceptable ranges. Most of the children benefit from surgery, especially when complete excision is accomplished. Segmentectomy and lobectomy are well tolerated in children without increase in morbidity and mortality. Therefore, resection of damaged part of the lung tissue may be preferred instead of removing high volume lung tissue.
