imaging of hydropneumothorax

Boerhaave's syndrome is a potentially fatal emergency, typically induced by forceful retching, which leads to increased intra-esophageal pressure. It commonly presents with vague symptoms such as chest pain or more classic symptoms like subcutaneous emphysema and vomiting. We present an unusual case of Boerhaave syndrome secondary to rapid and excessive intake of carbonated drinks in a 22-year-old male, who presented to our emergency department with atypical symptoms of fever and shortness of breath. Imaging studies showed left-sided hydropneumothorax with an esophageal pleural fistula, and multidisciplinary teams were involved in the patient's management...

BACKGROUND: Non-expandable lung (NEL) has severe implications for patient symptoms and impaired lung function, as well as crucial implications for the management of malignant pleural effusion (MPE). Indwelling pleural catheters have shown good symptom relief for patients with NEL; hence, identifying patients early in their disease is vital. With the inability of the lung to achieve pleural apposition following thoracentesis and the formation of a hydropneumothorax, traditionally, chest X-ray and clinical symptoms have been used to make the diagnosis following thoracentesis...

Parvimonas micra , an oral anaerobe and a known gastrointestinal microbiota, has also been found to be enriched in mucosal tissues of the colon. Our patient presented with chest pain, productive cough, and hypoxia. He was diagnosed with COVID-19 pneumonia with a suspected superimposed bacterial infection. After the initiation of treatment, the patient developed a right hydropneumothorax/loculated pleural effusion on X-ray. Bedside drainage was done, and cross-sectional imaging showed findings of pleural empyema...

Pneumothorax ex vacuo and trapped lung represent challenging clinical entities, especially in the context of pre-existing comorbidities. This case report outlines the diagnostic and management pathway of a 38-year-old patient with cerebral palsy who initially presented with empyema. Following the evacuation of the empyema, the patient developed pneumothorax ex vacuo, a rare phenomenon occurring due to a vacuum-like negative intrapleural pressure initiated by lung collapse. Initially suspected to have an infectious etiology based on laboratory findings, the patient was later found to have a large hydropneumothorax through a combination of imaging, laboratory studies, and clinical evaluations without confirming infection or malignancy...

BACKGROUND: Late-presenting congenital diaphragmatic hernia occurs beyond the neonatal period, and is relatively rare, presenting with nonspecific respiratory and gastrointestinal symptoms. CASE: We report a rare case of late-presenting congenital diaphragmatic hernia in a 7-year-old girl, who presented with abdominal pain, shortness of breath and fever on admission. Work-up revealed intrathoracic gastric perforation, acute pancreatitis and septic shock with a diaphragmatic defect...

Electrical impedance tomography (EIT) is a non-invasive technique for visualizing the internal structure of a human body. Capacitively coupled electrical impedance tomography (CCEIT) is a new contactless EIT technique that can potentially be used as a wearable device. Recent studies have shown that a machine learning-based approach is very promising for EIT image reconstruction. Most of the studies concern models containing up to 22 electrodes and focus on using different artificial neural network models, from simple shallow networks to complex convolutional networks...

OBJECTIVE: In complicated parapneumonic effusion or Empyema, approximately 25% of patients require surgical intervention which can be associated with a mortality risk of almost 20%. However, the use combination of rt-tPA and DNase in elderly patients with prohibitive surgical risk has improved outcomes. The main goal of our study is to highlight the utility of intrapleural thrombolysis in patients with prohibitive risk for surgery. METHODS: A retrospective record review study of patients (n=23) with complicated parapneumonic pleural effusion or empyema treated with tPA and DNase from January 1st of 2015 to March 18th, 2019 at VACHCS...

We present the case of a 35-year-old patient without pathological history who developed hemopneumothorax due to altitude barotrauma during a commercial airline flight. The computed tomography (CT) of the chest identified the presence of right hydropneumothorax and emphysema "blebs" and bubbles. After the therapeutic insertion of a drain tube, the patient returned to the country by land transport. Three weeks later, he was diagnosed with right-sided pleurisy based on a CT scan with contrast material. A surgical intervention was then performed, and three biopsy samples were taken; the histopathological result highlighted suggestive elements for the diagnosis of desquamative interstitial pneumonia (DIP)...

A 37-year-old male presented with left-sided hydropneumothorax. After drainage of fluid and air from the pleural cavity, chest radiograph and computed tomography of chest showed characteristic radiological image of ruptured hydatid cyst. The diagnosis was supported by positive echinococcal serology.

Congenital diaphragmatic hernias are rarely seen and they are usually diagnosed in the neonatal period. Congenital diaphragmatic de-fect, also known as Bochdalek hernia, usually occurs with the persistence of the pleuroperitoneal canal in the left posterolateral region of the diaphragm in the embryological period. Although it is rarely seen in the adults, conditions such as intestinal volvulus, strangulation, or perforation with congenital diaphragm defect progress with high mortality and morbidity. In this study, we reported our case that we operated for intrathoracic gastric perforation with congenital diaphragmatic defect...

Hydatid disease is a zoonosis caused by a larva of the tapeworm Echinococcus. All organs can be involved, but it is frequently located in liver for adults and lung for children. The clinical features are nonspecific. Imaging findings has an important place in the diagnosis and the follow-up. Rupture is the most common complication of a hydatic cyst and has a variety of imaging findings depending on the ruptured layer, the amount of air within the cyst and the type rupture. We report the case of a 10-year-old boy presenting shortness of breath and fever among other symptoms revealing by chest X-ray and thoracic CT scan, a lung ruptured hydatic cyst to the pleural cavity causing a tension hydro-pneumothorax and a superadded infection...

Portable chest radiography is a valuable tool in the intensive care unit. However, the supine position causes superposition of anatomical structures resulting in less reliable detection of certain abnormalities. Recently, a portable digital tomosynthesis (pDTS) prototype with a modified motorized X-ray device was developed. We aimed to compare the diagnostic value of pDTS to standard bedside chest radiography in the diagnosis of a posterior pneumothorax. A modified motorized X-ray device was developed to perform 15 radiographic projections while translating the X-ray tube 25 cm (10 cm ramp up and 15 cm during X-ray exposure) with a total radiation dose of 0...

Effusive pneumothorax can be hemopneumothorax, pyopneumothorax, or hydropneumothorax depending on the type of fluid compartment within the pleural cavity. Hydropneumothorax is the abnormal collection of air and serous fluid within the pleural cavity. Here, we report a case of a 34-year-old male who presented to the emergency department with cough and breathlessness. We did bedside point-of-care ultrasound-assisted clinical evaluation as the patient was vitally unstable, which showed "hydro point" and "defective barcode sign," which suggested hydropneumothorax...

Primary mediastinal synovial sarcomas constitute a rare subset of mediastinal tumors. The diagnosis is often delayed at the time of presentation impacting the five-year survival rate due to its highly aggressive natural history. We report a 22-year old female with a monophasic variant of the primary mediastinal synovial sarcoma. A 22-year-old female, with a two-month history of productive cough, fever, breathlessness, was referred to our center in view of persistent right-sided hydropneumothorax despite multiple thoracocenteses...

We report a diagnostically challenging case of a 77-year-old man who presented with shortness of breath and was found to have a large right hydropneumothorax with collapse of the right lung. A malignancy was suspected, but pleural fluid cytology and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT imaging were negative. He then underwent video-assisted thoracoscopy with biopsies of the pleura and chest wall which revealed malignant pleural mesothelioma (MPM). Older patients with early stage MPM are more likely to have false-negative FDG PET/CT results...

A 75-year-old man with a history of epithelioid mesothelioma and a right-sided indwelling pleural catheter (IPC) presented with a history of a purulent fluid drainage via the IPC. The pleural fluid cultured Klebsiella oxytoca and Enterococcus faecalis He was treated with a course of oral fluoroquinolone followed by uneventful IPC replacement. One and half hours postprocedure, the patient had a witnessed drop in conscious level accompanied by seizure like activity. Acute stroke was suspected and a CT head was performed...

OBJECTIVE: To analyze radiological changes in portable chest radiographs in coronavirus disease-19(COVID-19) patients to optimize the management of hospitalized patients. METHODS: We retrospectively reviewed 638 portable radiographs of 422 hospitalized COVID-19 patients with RT-PCR confirmed COVID-19 infection. All the radiographs were reported in a structured format by two experienced radiologists. A severity score was assigned to every Chest Xray (CXR) and correlation was done with the CT scans whenever available...

There are limited systematic studies on hematologic disease complicated by air leak syndrome (ALS). Physicians in radiology departments and hematology departments have a limited awareness of ALS.The aim of this study was to explore the similarities and differences in clinical data between the clinical group and imaging group in patients with hematologic disease complicated by ALS.Clinical and CT data for 59 patients with hematologic disease complicated by ALS in our hospital were retrospectively reviewed. Patients were assessed by clinical grouping and image grouping...

Thoracic endometriosis syndrome (TES) is an extremely rare disorder, and it is defined as the presence of functional endometrial tissue in pleura, airways, and lung parenchyma. We describe a rare case of a 29-year-old nulliparous female who presented with abdominal pain, dyspareunia, and shortness of breath. She complained of worsening of symptoms around the menstrual cycle. Initial workup showed markedly elevated CA-125 levels. A chest radiograph and CT of the chest, abdomen, and pelvis demonstrated large tension hydrothorax, ascites, and bilateral ovarian cysts...

BACKGROUND: Pneumopericardium is an uncommon clinical finding. It most commonly occurs after chest trauma but can also emerge as a complication following interventional or surgical procedures and can result in life-threatening complications. A high index of clinical suspicion should be present and once the condition is recognized, it should be managed promptly. Paucity of literature on pneumopericardium makes outlining any new case of paramount importance to emphasize the aspects of diagnosis and management of this rare condition...
