Double accessory fissures in the upper lobe of the right lung (double azygos fissures?): high resolution computed tomography appearance

This study aimed to determine the measurements of the cochlea among healthy subjects and hearing deafness subjects using a High Resolution Computed Tomography (HRCT). A total of 230 temporal bone HRCT cases were retrospectively investigated in the period spanning from 2011 to 2015. Three 64-slice units were used to examine patients with clinical complaints of hearing loss conditions at three Radiology departments in Khartoum, Sudan. For the control group (A) healthy subjects, the mean width of the right and left cochlear were 5.61±0.40 mm and 5.56±0.58 mm, the height were 3.56±0.36 mm and 3.54±0.36 mm, the basal turn width were 1.87±0.19 mm and 1.88 ±0.18 mm, the width of the cochlear nerve canal were 2.02±1.23 and 1.93±0.20, cochlear nerve density was 279.41±159.02 and 306.84±336.9 HU respectively. However, for the experimental group (B), the mean width of the right and left cochlear width were 5.38±0.46 mm and 5.34±0.30 mm, the height were 3.53±0.25 mm and 3.49±0.28mm, the basal turn width were 1.76±0.13 mm, and 1.79±0.13 mm, the width of the cochlear nerve canal were 1.75±0.18mm and 1.73±0.18mm, and cochlear nerve density were 232.84±316.82 and 196.58±230.05 HU, respectively. The study found there was a significant difference in cochlea’s measurement between the two groups with a p-value < 0.05. This study had established baseline measurements for the cochlear for the healthy Sudanese population. Furthermore, it found that HRCT of the temporal bone was the best for investigation of the cochlear and could provide a guide for the clinicians to manage congenital hearing loss.

Introduction. Non-tuberculosis mycobacteria are environmental organisms found in soil and water worldwide, and an infection caused by non-tuberculosis mycobacteria is less frequently found than the one associated with Mycobacterium tuberculosis. This study was designed to evaluate data relating to non-tuberculosis mycobacteria in patients with clinical importance. Material and Methods. Of 12 patients (pts) admitted to the Department of Pulmonology, Clinical Centre of Serbia in Belgrade during 2010- 2011, seven (58.33%) were men and five (41.67%) were women. Bacteriological and radiographic findings, co?morbidity, treatment management and outcome were evaluated from medical records. Results. Using GenoType? Mycobacterium CM/AS (Hain Lifescience) assays for identification of isolated cultures of NTM) M.xenopi was found in six (50%) pts, M.avium complex in two (16.67%) pts, M.kansasii and M.xenopi in one (8.33%), M. gordone, M.abscessus and M.peregrinum in one (8.33%) patient each. Cavitary lesions were most frequently determined on high resolution computed tomography in five (41.67%) pts, followed with consolidation in two (16.67%) pts, cavitation with fibronodular lesions and bronchiectasis in one (8.33%) patient each. Comorbidities were noticed in nine (75%) pts, with chronic obstructive pulmonary diseases most frequently found in six (50%) pts. According to American Thoracic Society definition and criteria, treatment was administered in nine (75%) pts. Conclusion. In order to find the right treatment, it is important to identify non-tuberculosis mycobacteria lung infection by culture methods, at least two positive, accompanied with high resolution computed tomography changes.

Objective: To describe the cochlear anatomy among Filipinos through high resolution computed tomography (HRCT) imaging. Methods: Design: Retrospective Study Setting: Tertiary Private University Hospital Patients: Cochlear images retrospectively obtained from computed tomography (CT) scans of subjects who underwent cranial, facial, paranasal sinus and temporal bone computed tomography from October 2009 to July 2010 were reconstructed and analyzed. Results: 388 cochlear images were obtained from the scans of 194 subjects (101 males and 93 females, aged 1 to 90 years old, mean = 52 years) and reconstructed for analysis. The mean coiled cochlear height measured 4.36 mm on the right (A.D.) and 4.34 mm on the left (A.S.). Measurement from the oval window to the distal end of the basal turn (equivalent to the horizontal dimension of the cochlea or the mean length of the basal turn) was 7.55 mm A.D. and 7.60 mm A.S. The vertical and horizontal dimensions of right and left cochleas were identical in all subjects (S.D. = 0.35). The right and left cochlear turns were identical in each subject, exhibiting 2 ½ turns in 92.3% of subjects and 2 ¾ turns in 7.7% of subjects.The cochlear dimensions were similar in all subjects, regardless of age. No cochlear ossification or malformation was noted on any CT image. Conclusion: The 7.55 mm mean length of the cochlear basal turn among Filipinos in this study was 1.24 mm shorter than the average length of the basal turn of 8.81 mm reported elsewhere. Further studies of the cochlear dimensions in specific age groups and its correlation to audiometric status are recommended to determine other significant physiologic correlations.

The Right

The case of a patient with cough and asthma after activity that each had a 1-month duration is reported. Chest high-resolution computed tomography (HRCT) showed visceral pleural thickening in both upper lungs (especially the right lung), which was accompanied by fibrous strips and patches near the pleura, and these were accompanied by distraction bronchiectasis. Idiopathic pleuropulmonary elastosis was confirmed by thoracoscopic lung biopsy. The patient was treated with acetylcysteine, but their asthma worsened after activity and their lung function decreased significantly after 10 months. Idiopathic pleuroparenehymal fibroelastosis is a rare new type of idiopathic interstitial pneumonia, which has no effective treatment except for lung transplantation.
