A case of intrathoracic desmoid tumor with pulmonary Mycobacterium abscessus disease

Publication date: Available online 20 January 2020Source: Respiratory Medicine Case ReportsAuthor(s): Takuma Katano, Eri Hagiwara, Hiromasa Arai, Midori Sato, Takafumi Yamaya, Michihiko Tajiri, Takashi OguraAbstractA 68-year-old man who was on treatment for pulmonary Mycobacterium avium complex complained a worsening of sputum. Although he archived negative sputum culture two months ago, sputum culture tests revealed the newly isolation of Mycobacterium abscessus repeatedly. Chest computed tomography showed newly-appeared extra-pulmonary mass lesion in contact with a cyst at the bottom of his right lung. From the results of contrast-enhanced magnetic resonance imaging, we first suspected loculated pleural effusion due to Mycobacterium abscessus infection. A thoracoscopic examination was performed as the right pneumothorax developed, and the pleural lesion was successfully resected and diagnosed as an intrathoracic desmoid tumor. Intrathoracic desmoid tumor is very rare, and this is the first report of a case with pulmonary Mycobacterium abscessus disease.

CONCLUSIONS: In patients with suspected blunt thoracoabdominal trauma, positive POCS findings are helpful for guiding treatment decisions. However, with regard to abdominal trauma, a negative POCS exam does not rule out injuries and must be verified by a reference test such as CT. This is of particular importance in paediatric trauma, where the sensitivity of POCS is poor. Based on a small number of studies in a mixed population, POCS may have a higher sensitivity in chest injuries. This warrants larger, confirmatory trials to affirm the accuracy of POCS for diagnosing thoracic trauma. PMID: 30548249 [PubMed - as supplied by publisher]

Rationale: Radiofrequency ablation (RFA) is a safe and effective local treatment modality with a low complication rate and is commonly used to treat hepatocellular carcinoma (HCC). The clinical outcome of RFA may be closely related to the location, size, and shape of index tumors, and major complications, including hemorrhage, liver abscess, infarction, visceral organ perforation, hemothorax, pneumothorax, tumoral seeding, and hepatic failure. Cardiac tamponade is a rare and serious life-threatening complication associated with RFA. To date, a review of the medical literature reported 5 cases of cardiac tamponade after R...

Background: There is increasing evidence in patients with Primary Spontaneous Pneumothorax (PSP) of emphysema-like change (ELC) and inflammation. Pulmonary function tests (PFTs) are global metrics, not sensitive to subtle disease. Computed tomography scans can provide detailed structural, but not direct functional, information. Hyperpolarised 129Xenon magnetic resonance imaging (MRI) allows functional assessment of ventilation.Methods: Patients underwent 129Xe MRI ventilation scan with a single breath-hold of 1L 129Xe with ~10% hyperpolarisation. Percentage ventilation of lung receiving 129Xe hyperpolarized gas were analys...

Rationale: Langerhans’ cell histiocytosis (LCH), also called histiocytosis X, is an uncommon disorder manifesting in a variety of ways. Although LCH can involve various organs including bone, skin, and lymph nodes, multisystem involvement of LCH is rare in adults. Patient concerns: A 31-year-old woman first presented to our hospital with left leg pain. She had a history of a 20-kg weight gain over three months. Diagnoses: X-ray, magnetic resonance imaging (MRI), computed tomography (CT), and bone scan images revealed enhancing lesions in the left femur and right temporal bone, multiple cystic lesions in the l...

AbstractLung cancer patients often experience potentially life-threatening medical urgencies and emergencies, which may be a direct or indirect result of the underlying malignancy. This pictorial review addresses the most common thoracic, neurological and musculoskeletal medical emergencies in lung cancer patients, including superior vena cava syndrome, pulmonary embolism, spontaneous pneumothorax, cardiac tamponade, massive haemoptysis, central airway obstruction, oesophagorespiratory fistula, malignant spinal cord compression, carcinomatous meningitis, cerebral herniation and pathological fracture. Emphasis is placed on ...

Postmortem computed tomography (PMCT) is becoming a commonly used modality in routine forensic investigation [1,2]. Postmortem CT and magnetic resonance imaging have been proved to be useful for forensic examinations, especially in victims of trauma [3,4]. These imaging methods have revolutionized not only forensic diagnosis but also the documentation of evidence that can be used in court proceedings [5]. In addition, PMCT is a superior technique for finding air within the body, such as pneumothorax and gas embolism in the heart and great vessels [6,7].

Pleural disease is common. Radiological investigation of pleural effusion, thickening, masses, and pneumothorax is key in diagnosing and determining management. Conventional chest radiograph (CXR) remains as the initial investigation of choice for patients with suspected pleural disease. When abnormalities are detected, thoracic ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) can each play important roles in further investigation, but appropriate modality selection is critical.

Postmortem imaging is a useful technique for determining the cause of death in cases of natural death involving no damage to the body surface, or when the bereaved do not wish to have an autopsy performed. Computed tomography (CT) and/or magnetic resonance imaging are mainly performed to derive internal body information. Many reports have confirmed that postmortem imaging is useful in the detection of various causes of death and/or conditions such as the presence of putrefactive gases, pneumothorax with a mediastinal shift, or comminuted fracture [1 –3].

Fishman, Jan Fritz Hereditary multiple exostoses (HME) is an autosomal dominant disorder characterized by the formation of multiple osteochondromas. Because of its superior soft tissue contrast and absence of ionizing radiation, magnetic resonance imaging is the first choice imaging technique for the evaluation of complex lesions and complications related to HME. However, multidetector computed tomography (MDCT) also can be of value in the evaluation of patients with HME, which...

Conclusion Catamenial pneumothorax is the most common presentation of thoracic endometriosis syndrome and should always be suspected in women in childbearing age. Treatment option are still debated but best results are achieved by videothoracoscopic pleurodesis combined with hormonal therapy.
