ABSTRACT

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.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):951-959. doi: 10.12998/wjcc.v9.i4.951.

ABSTRACT

BACKGROUND: Pheochromocytoma is a rare catecholamines-secreting tumor arising from chromaffin cells in the adrenal medulla. It classically presents with paroxysmal hypertension, headaches, palpitations, sweating, and metabolic disorders. Atypical presentations such as acute myocardial infarction, heart failure, cardiomyopathy, stroke, and transient erythrocytosis have been infrequently documented.

CASE SUMMARY: We describe the case of a 72-year-old man diagnosed with pheochromocytoma presenting with non-ST segment elevation myocardial infarction, heart failure, and transient erythrocytosis with nonobstructed coronary arteries. This was his second heart attack. The patient was previously diagnosed with myocardial infarction, and an immense mass was found on the left adrenal gland 3 years prior. Based on clinical and laboratory findings, a diagnosis of pheochromocytoma was confirmed. His coronary angiogram showed nonobstructed coronary arteries except for a myocardial bridge in the left anterior descending branch. This was a form of type-2 myocardial infarction. The myocardial cell lesions were caused by sudden secretion of catecholamines by the pheochromocytoma. Even more atypically, his hemoglobin level was obviously elevated at admission, but after a few days of treatment with an alpha-adrenergic receptor blocker, it dropped to normal levels without additional treatment.

CONCLUSION: Pheochromocytoma may be a cause of acute myocardial infarction, heart failure, and transient erythrocytosis.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):854-863. doi: 10.12998/wjcc.v9.i4.854.

ABSTRACT

BACKGROUND: Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare disease characterized by the rapid appearance of aging with an onset in childhood. Serious cardiovascular complications can be life-threatening events for affected patients and the cause of early death. Herein we report a HGPS patient with osteosarcoma hat was successfully managed and is alive 13 years after the diagnosis. This is the first report describing the detailed surgical procedure and long-term follow-up of osteosarcoma in a patient with HGPS.

CASE SUMMARY: The patient was diagnosed with HGPS at 5 years of age with typical features and was referred to our department with a suspected bone tumor of the left proximal tibia at the age of 18. Open biopsy of the tibial bone tumor revealed a conventional fibroblastic osteosarcoma. We have developed and performed a freez ing technique using liquid nitrogen for tumor reconstruction. This technique overcame the small size of the tibia for megaprosthesis and avoided amputation and limb salvage was achieved 13 years post-operatively. Although the patient had a number of surgical site complications, such as wound dehiscence, and superficial and deep infections due to vulnerable skin in HGPS, no recurrence or metastases were detected for 13 years, and she walks assisted by crutches. Her general health was good at the latest follow-up at 31 years of age.

CONCLUSION: A HGPS patient with osteosarcoma was successfully managed and she was alive 13 years after the diagnosis.

Immediate implant placement in combination with platelet rich-fibrin into extraction sites with periapical infection in the esthetic zone: A case report and review of literature

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):960-969. doi: 10.12998/wjcc.v9.i4.960.

ABSTRACT

BACKGROUND: In this case, platelet-rich fibrin (PRF) was added to guided tissue regeneration as a biomaterial in proper order for immediate planting in aesthetic area with periapical infection.

CASE SUMMARY: With the history of endodontic failure in maxillary central incisor, a 34-year-old female patient required the extraction of maxillary anterior residual root and immediate implantation. Cone beam computed tomography and clinical observation were used to assess the regeneration of soft and bone tissue. Before operation, cone beam computed tomography showed the anterior residual root had serious periapical periodontitis with insufficient labial bone in the aesthetic zone. The patient underwent immediate implant placement and reconstruction of the bone substitution by modified guided bone regeneration. The barrier was a three-layer structure of P RF-collagen membrane-PRF that covered the mixture of PRF and Bio-Oss to promote both osteogenesis and soft tissue healing. At 6 mo postoperatively, the definitive crown was placed after accomplished finial impression. One-year follow-up showed a satisfactory aesthetic effect with no obvious absorption of the labial bone and soft tissue.

CONCLUSION: The use of PRF in combination with guided bone regeneration can serve as a reliable and simple adjuvant for immediate implanting in infected socket and result in a stable osteogenic effect with good aesthetic outcome.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):764-773. doi: 10.12998/wjcc.v9.i4.764.

ABSTRACT

Chiari malformations encompass various radiological and clinical entities, sharing the herniation of the rhombencephalic structures through the foramen magnum as a common characteristic. They can be symptomatic or asymptomatic. The therapeutic strategies for these malformations differ on the basis of the diverse pathophysiologic processes that cause them. As Chiari malformations are caused by various pathophysiologic processes, they must be recognized promptly to select the best treatment for each single case.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):970-975. doi: 10.12998/wjcc.v9.i4.970.

ABSTRACT

BACKGROUND: Aortic dissection (AD) is an emergent and life-threatening disorder, and its in-hospital mortality was reported to be as high as 24.4%-27.4%. AD can mimic other more common disorders, especially acute myocardial infarction (AMI), in terms of both symptoms and electrocardiogram changes. Reperfusion for patients with AD may result in catastrophic outcomes. Increased awareness of AD can be helpful for early diagnosis, especially among younger patients.

CASE SUMMARY: We report a 28-year-old man with acute left side chest pain without cardiovascular risk factors. He was diagnosed with acute inferior ST-segment elevation myocardial infarction (STEMI), which, based on illness history, physical examination, and intraoperative findings, was eventually determined to be type A AD caused by Marfan syndrome. Emergent coronary angiography revealed t he anomalous origin of the right coronary artery as well as eccentric stenosis of the proximal segment. Subsequently, computed tomography angiography (CTA) showed intramural thrombosis of the ascending aorta. Finally, the patient was transferred to the cardiovascular surgery department for a Bentall operation. He was discharged 13 d after the operation, and aortic CTA proved a full recovery at the 2-year follow-up.

CONCLUSION: It is essential and challenging to differentiate AD from AMI. Type A AD should be the primary consideration in younger STEMI patients without cardiovascular risk factors but with outstanding features of Marfan syndrome.

Gastroduodenal intussusception caused by gastric gastrointestinal stromal tumor: A case report and review of the literature

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 6;9(4):838-846. doi: 10.12998/wjcc.v9.i4.838.

ABSTRACT

BACKGROUND: Gastric gastrointestinal stromal tumor (GIST) is the most common etiology of gastroduodenal intussusception. Although gastroduodenal intussusception caused by gastric GIST is mostly treated by surgical resection, the first case of gastroduodenal intussusception caused by gastric GIST was treated by endoscopic submucosal dissection (ESD) in Japan in 2017.

CASE SUMMARY: An 84-year-old woman presented with symptoms of postprandial fullness with nausea and occasional vomiting for a month. Initially, she visited a local clinic for help, where abdominal sonography revealed a space-occupying lesion around the liver, so she was referred to our hospital for further confirmation. Abdominal sonography was repeated, which revealed a mass with an alternating concentric echogenic lesion. Esophagogastroduodenoscopy (EGD) was performed under the initi al impression of gastric cancer with central necrosis and showed a tortuous distortion of gastric folds down from the lesser curvature side to the duodenal bulb with stenosis of the gastric outlet. EGD was barely passed through to the 2nd portion of the duodenum and a friable ulcerated mass was found. Several differential diagnoses were suspected, including gastroduodenal intussusception, gastric cancer invasion to the duodenum, or pancreatic cancer with adherence to the gastric antrum and duodenum. Abdominal computed tomography for further evaluation was arranged and showed gastroduodenal intussusception with a long stalk polypoid mass 5.9 cm in the duodenal bulb. Under the impression of gastroduodenal intussusception, ESD was performed at the base of the gastroduodenal intussusception; unfortunately, a gastric perforation was found after complete resection was accomplished, so gastrorrhaphy was performed for the perforation and retrieval of the huge polypoid lesion. The gastric tu mor was pathologically proved to be a GIST. After the operation, there was no digestive disturbance and the patient was discharged uneventfully on the 10th day following the operation.

CONCLUSION: We present the second case of gastroduodenal intussusception caused by GIST treated by ESD. It is also the first case report of gastroduodenal intussusception by GIST in Taiwan, and endoscopic reduction or resection is an alternative treatment for elderly patients who are not candidates for surgery.
