Abdominal alterations in disseminated paracoccidioidomycosis: computed tomography findings

Objective To evaluate the incidence and spectrum of abdominal computed tomography imaging findings in patients with paracoccidioidomycosis. Materials and Methods Retrospective analysis of abdominal computed tomography images of 26 patients with disseminated paracoccidioidomycosis. Results Abnormal abdominal tomographic findings were observed in 18 patients (69.2%), while no significant finding was observed in the other 8 (30.8%) patients. Conclusion Computed tomography has demonstrated to play a relevant role in the screening and detection of abdominal abnormalities in patients with disseminated paracoccidioidomycosis.

Aspectos tomográficos da tuberculose pulmonar em pacientes adultos com AIDS

found in 31 (68.8%) cases, pleural effusion in 29 (64.4%), centrilobular nodules with segmental distribution in 26 (57.7%), consolidation in 24 (53.3%), confluent micronodules in 17 (37.7%), poorly defined nodules with centrilobular distribution in 16 (35.5%), tree-in-bud pattern in 13 (28.9%), bronchial wall thickening in 12 (26.6%), thick-walled cavity in 10 (22.2%), miliary nodules in 9 (20%), and cylindrical bronchiectasis in 6 (13.3%). Among the 45 patients, 35 (77.8%) presented CD4 count < 200 cel/mm3 and 10 (22.2%) presented CD4 count ≥ 200 cel/mm3. Conclusion: Differently from reports in the literature, the authors conclude that mediastinal and/or hilar lymph node enlargement and consolidation were significantly most frequent in patients with CD4 count ≥ 200 cel/mm3. However, lymph nodes with hypodense center were most often observed in severely immunosuppressed patients with CD4 count < 200 cel/mm3.

Clinical and radiological aspects in Melnick-Needles syndrome

Melnick-Needles syndrome is an X-linked dominant bone dysplasia, lethal in males, characterized by a typical facies and characteristic radiological findings: including sclerosis of skull base and mastoids. S-shaped appearance of tibia; cortical irregularities with a ribbon appearance of the ribs. About 48 well-documented cases have been reported, most of them were sporadic. Parental transmission has been published in only 11 kindreds. We are presenting the first Brazilian family with mother-daughter transmission. The proposita presented the typical clinical and radiological features with characteristic facies, severe thoracic cage restriction and pulmonary hypertension. Her mother was more mildly affected.

Hidrocolpo por ectopia ureteral em hemivagina associado a displasia renal: relato de caso e revisão da literatura

The authors report a case of congenital hydrocolpos due to vaginal malformation (vaginal septae) associated with ectopic ureter and renal displasia. Several imaging diagnostic procedures (ultrasonography, nuclear medicine, intravenous urography and computed tomography) were performed. A review of the literature on hydrocolpos and its association with urinary malformations is also presented.
