“…CLD is a constellation of diverse lung disorders that originate from various causes but they have in common an anatomical cystic deformity. Due to its etiological heterogeneity, CLD can be classified based on the underlying pathophysiologic mechanisms: congenital, genetic, infectious, inflammatory, lymphoproliferative, neoplastic, and smokingrelated [10,11]. CLD must also be distinguished from emphysema, cavity, bulla, pneumatocele, and honeycombing, all of which feature lucencies that mimic a pulmonary cyst.…”

Cistična bolest pluća (CLD) je grupa oboljenja pluća koju karakteriše prisustvo multiplih cisti, definisanih kao translucencije ispunjene vazduhom ili zone niske atenuacije, oivičene tankim zidom (uglavnom < 4mm). Često se mešaju sa džinovskim bulama koje su uobičajene kod pacijenata sa emfizemom. Prikaz slučaja: Žena stara 76 godina sa prethodnom medicinskom istorijom o subokluzivnim smetnjama primljena je na odeljenje hirurgije. Uzgredno, prilikom preoperativnog pregleda RTG snimka grudnog koša uočena je džinovska bula u desnom plućnom krilu. Kompjuterizovana tomografija je potvrdila nalaz, ali zbog svoje debljine zida promena je svrstana u plućne ciste koje imaju potpuno drugačiji pristup u lečenju. Zbog toga, pacijentkinja nije podvrgnuta operaciji i lečena je konzervativno. Zaključak: Glavna razlika između džinovskih bula i plućnih cisti je debljina zida, ukoliko je od 1-4 mm radi se o plućnoj cisti, za razliku od bule čiji je zid tanji od 1 mm. Ključne reči: ciste, bule, HOBP, imidžing Summary: Cystic lung disease (CLD) is a group of lung disorders characterized by the presence of multiple cysts, defined as air-filled lucencies or low-attenuating areas, bordered by a thin wall (usually < 4 mm). It is very often mixed with giant bullaes which are common in patients with emphysema. Case report: A 76-year-old woman with a medical history of subocclusive disturbance was admitted to surgery department. Accidentally, during preoperative examination, chest X-ray revealed giant bullae in the right lung. CT scan confirmed it, but due to the wall thickness the changes have been classified into pulmonary cyst which have a completely different approach in treatment. Thus, patient underwent without surgery and was treated conservatively. Conclusion: The main difference between a giant bullae and a pulmonary cyst is in wall thickness, if it measures between 1 and 4 mm it is pulmonary cyst, unlike bullae whose wall is thinner than 1mm.

“…12 Polymerase chain reaction followed by a suspension assay identification system that detects the most common 17 species of mycobacteria was also successful in definitively identifying MAC as the cause of infection, 15,19 more so when the DNA probe failed. 24 The sensitivity and specificity of PCR-suspension array are 97.1% and 98.8%, respectively. 15 Another case used 16S rRNA gene sequencing to identify a MAC isolate of the right posterior lower lobe of the lung.…”

Extrapulmonary Mycobacterium avium complex infections in immunocompetent patients

The Mycobacterium avium complex (MAC) includes ubiquitous bacteria that typically cause infection in immunocompromised patients. This paper reviews the presentation, diagnosis, pathogenesis, and treatment of extrapulmonary MAC infections in immunocompetent patients by compiling information from case reports identified by a PubMed search. Mycobacterium avium complex infections in immunocompetent patients can present primarily with extrapulmonary symptoms, and this makes the diagnosis of MAC infection in these patients more difficult. The American Thoracic Society has not established criteria for the diagnosis of extrapulmonary MAC infections; testing for MAC should be based on clinical suspicion or after the exclusion of all other causative agents. Methods of testing should include molecular and biochemical tests, since these tests provide more definitive identification than routine cultures. Extrapulmonary presentations usually respond well to macrolide based multi-drug regimens started as soon as a MAC infection is identified. Key words: Mycobacterium avium, infection, diagnosis, treatment

“…For systematic research, we used in Pubmed the terms (myobacterial infection, tuberculosis and bronchogenic cyst). In the 11 clinical cases that were found [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , clinical data was obtained by full text in 6 papers and in 2 by abstract. The diagnostic method was noted of a total of 9 cases of bronchogenic cyst infected by mycobacterium; in a paper two clinical cases was described [20] .…”

“…The diagnostic method was noted of a total of 9 cases of bronchogenic cyst infected by mycobacterium; in a paper two clinical cases was described [20] . In one case, the diagnosis was possible preoperatively, after bacteriological culture, by CT-guided fine-needle aspiration of the lesion [21] ; in the other cases [20] , [22] , [23] , [24] , [25] , [26] , [27] the diagnosis was postoperative, by bacteriological culture of the tissue in 2 cases [22] , [23] and by histology in 5 cases [20] , [24] , [25] , [26] , [27] .…”

A 63 year old woman presenting chronic back pain and neuralgia had abnormal shadow on chest radiograph. She has a history of pulmonary tuberculosis treated in 1977. The chest-CT scan showed a soft tissue mass in the lower lobe of the right lung and a cystic mass in the paravertebral region. The patient had right lower lobectomy and complete excision of a paraoesophageal cyst. Both masses were bronchogenic cysts at histology. The patient had an uneventful discharge the seventh postoperative day. After 4 years and 7 months of follow-up with CT-scann, the patient was free of symptoms with no evidence of recurrent disease.
