Parenchymal Damage

The unilateral destroyed lung is an important cause of morbidity and mortality. The commonest cause of destroyed lung is total post tuberculous sequelae. Primary lung tumors, mediastinal masses, vascular abnormalities, and some others are considered to be other causes of lung destruction. A study was undertaken at the National Institute of Diseases of the Chest and Hospital (NIDCH) on 600 cases from January 2016 to December 2020 to evaluate the etiopathogenesis of unilateral lung destruction and to evaluate hilar structures & the nature and extent of parenchymal damage. The study was performed on 600 patients with unilateral lung destruction, of whom 416(69.33%) had left lung destruction. Pulmonary tuberculosis was found to be the cause in 504(84%) patients. All patients had an X-ray chest and CT scan of the chest (contrast CT/ HRCT). However, 96(16%) non-tuberculous patients had their main bronchi occluded with extraluminal compression or by the intraluminal lesion. TAJ 2021; 34: No-1: 75-79

Tracheal Bifurcation

The article presents a case of successful surgical treatment of a 3-month-old child with a rare pathology – tuberculosis lesion of the intrathoracic lymph nodes causing compression of the left main bronchus. The child was admitted with signs of respiratory failure. An X-ray examination revealed signs of emphysema of the left lung. According to the data of contrast CT, a volumetric hypodensive formation was detected, which slightly accumulated contrast, with a capsule up to 0,3 cm thick, located in the area of the tracheal bifurcation, causing compression of the left main bronchus, esophagus, pulmonary bifurcation. During tracheobronchoscopy, a narrowing of the main bronchus to 1 mm was found immediately after bifurcation of the trachea. During the operation, a formation with a diameter of up to 2 cm was removed. According to the results of a morphological study, the formation is regarded as tuberculous granulomatous inflammation of the lymph node. The rarity of the pathology causes difficulties in diagnosis and treatment.

We observed a case of chronic left-sided maxillary rhinosinusitis of tuberculous etiology. K., 57 years old, has been registered with the State Medical Institution "Phthisiology" for infiltrative pulmonary tuberculosis since 1998.He was repeatedly treated in a tuberculosis hospital and outpatient with short courses. In January 2000, he was admitted to the Kazan City Tuberculosis Hospital due to complaints of cough with scant sputum, weakness, shortness of breath during physical exertion; negative X-ray dynamics was also observed. After clinical, radiological, laboratory and bacteriological examination methods, he was clinically diagnosed with infiltrative tuberculosis of the upper lobe of the left lung in the phase of decay and contamination of CD (+).

Aim: To describe the case of rare benign lymphoproliferative disorder — pulmonary nodular lymphoid hyperplasia in the patient with previous pulmonary tuberculosis. Materials and Methods: In the case of pulmonary nodular lymphoid hyperplasia clinical, laboratory, instrumental and morphological examination was performed. Results: 44-year-old woman in 7 years after successfully treated infiltrative drug-susceptible tuberculosis of the right lung, was hospitalized with a suspected tumor of the left lung root. The patient underwent left-sided pneumonectomy with lymph nodes dissection. The results of histopathological and immunohistochemical studies evidenced on nodular lymphoid hyperplasia of the left lung. Conclusion: Pulmonary nodular lymphoid hyperplasia is a rare lymphoproliferative disorder of the lung with favorable prognosis. For the purpose of differential diagnosis, it is necessary to apply immunohistochemistry.

Abstract Background The stone composition has a great influence on the outcome of its treatment. There are several tests to predict the composition of stones preoperatively and stone analysis postoperatively. Herein, we want to evaluate if the stone composition could be predicted from plain X-ray KUB (PKUB) and/or non-contrast CT (NCCT) validated by in vitro X-ray powder diffraction analysis (XRD). Methods Between April 2014 and March 2016, 100 cases with urinary tract stones were included in the study. The radio-opacity of the stones in PKUB, stone density by NCCT, and after stone extraction, XRD were performed. Statistical analysis for the results was performed using Chi-square and Fisher exact tests for categorical variables and Mann–Whitney U and Kruskal–Wallis H for the nonparametric variables. The receiver operating characteristic curve was constructed to determine the best cutoff value. Results This study included 74 males and 26 females with a median age of 32 years (range 2–70). Regarding the radio-opacity by PKUB, there were 30 stones dense opaque, 44 opaque, 21 faint opaque, and 5 radiolucent. XRD revealed 97 mixed and 3 pure stones. The calcium oxalate monohydrate (COM) stone composition could be predicted in dense opaque stone by PKUB in 75.9% and urate composition in the radiolucent stone by 40%. The cutoff value of HU density by NCCT to the dense opaque stones in the PKUB was > 1020 and for radiolucent stones was < 590. Conclusion Stone radio-opacity by PKUB and its attenuation value by NCCT could successfully predict its calcium oxalate monohydrate, struvite, and urate composition. However, the chemical stone analysis is still required as most stones are mixed.

Unilateral primary pulmonary hypoplasia is rare in adulthood (UPHA); it is characterized by a decreased number of bronchial segmentation and decreased/absent alveolar air space. Classical chest X-ray may be confusing, and the biological tests are unspecific. We present a case of UPHA in a 60-year-old female, smoker, with 3 term normal deliveries, who presented with late recurrent pneumonias and bronchiectasis-type symptomathology, arterial hypertension, and obesity. Chest X-rays revealed opacity in the left lower pulmonary zone, an apparent hypoaerated upper left lobe and left deviation of the mediastinum. Preoperatory multidetector computer tomography (MDCT) presented a small retrocardiac left lung with 5-6 bronchial segmentation range and cystic appearance. After pneumonectomy the gross specimen showed a small lung with multiple bronchiectasis and small cysts, lined by hyperplasic epithelium, surrounded by stromal fibrosclerosis. We concluded that this UPHA occurred in the 4–7 embryonic weeks, and the 3D MDCT reconstructions offered the best noninvasive diagnosis.

At birth, the transition to newborn life is triggered by lung aeration, which stimulates a large increase in pulmonary blood flow (PBF). Current theories predict that the increase in PBF is spatially related to ventilated lung regions as they aerate after birth. Using simultaneous phase-contrast X-ray imaging and angiography we investigated the spatial relationships between lung aeration and the increase in PBF after birth. Six near-term (30-day gestation) rabbits were delivered by caesarean section, intubated and an intravenous catheter inserted, before they were positioned for X-ray imaging. During imaging, iodine was injected before ventilation onset, after ventilation of the right lung only, and after ventilation of both lungs. Unilateral ventilation increased iodine levels entering both left and right pulmonary arteries (PAs) and significantly increased heart rate, iodine ejection per beat, diameters of both left and right PAs, and number of visible vessels in both lungs. Within the 6th intercostal space, the mean gray level (relative measure of iodine level) increased from 68.3 ± 11.6 and 70.3 ± 7.5%·s to 136.3 ± 22.6 and 136.3 ± 23.7%·s in the left and right PAs, respectively. No differences were observed between vessels in the left and right lungs, despite the left lung not initially being ventilated. The increase in PBF at birth is not spatially related to lung aeration allowing a large ventilation/perfusion mismatch, or pulmonary shunting, to occur in the partially aerated lung at birth.
