A 15-day-old female newborn presenting nasal obstruction since birth underwent computed tomography of the paranasal sinuses in our department due to clinical suspicion of choanal atresia. The patient presented no other complaints. Computed tomography () allowed the diagnosis of pyriform aperture stenosis, which is a rare cause of nasal obstruction in neonates and was first described in 1989.() Pyriform aperture stenosis becomes particularly significant during the first two months of life when infants are mandatory nose breathers.

ABSTRACT Technical advances in magnetic resonance imaging have allowed to accurately detect and grade endolymphatic space distension in Ménière disease; this was only possible in post-mortem histological studies until a few years ago. Magnetic resonance imaging rules out other causes of vertigo and hearing loss, and is able to evaluate the cochlear and vestibular compartments of the endolymphatic space using a dedicated protocol.

The importance of apnea in patients undergoing angiography of thoracic vessels – a protocol for acute pulmonary thromboembolism research

This was 37-year-old woman, 10 days after surgery, who underwent breast prosthesis replacement, abdominoplasty and liposuction. Upon admission, she was hemodynamically stable, febrile and reported constant pain on left hemithorax region, but without dyspnea. An angio-CT of thoracic vessels was carried out. During intravenous injection of contrast agent, the patient was anxious and started crying during the exam. We believe that, a Valsalva maneuver was performed on inspiration apnea requested during the exam therefore causing an intrathoracic pressure that resulted […]

Advances in lung ultrasound

ABSTRACTUltrasound examination of the chest has advanced in recent decades. This imaging modality is currently used to diagnose several pathological conditions and provides qualitative and quantitative information. Acoustic barriers represented by the aerated lungs and the bony framework of the chest generate well-described sonographic artifacts that can be used as diagnostic aids. The normal pleural line and A, B, C, E and Z lines (also known as false B lines) are artifacts with specific characteristics. Lung consolidation and pneumothorax sonographic […]

Correlation of Thyroid Imaging Reporting and Data System [TI-RADS] and fine needle aspiration: experience in 1,000 nodules

ABSTRACTObjectiveTo correlate the Thyroid Imaging Reporting and Data System (TI-RADS) and the Bethesda system in reporting cytopathology in 1,000 thyroid nodules.Methods A retrospective study conducted from November 2011 to February 2014 that evaluated 1,000 thyroid nodules of 906 patients who underwent ultrasound exam and fine needle aspiration.Results A significant association was found between the TI-RADS outcome and Bethesda classification (p

Normalization of lymphocyte count after high ablative dose of I-131 in a patient with chronic lymphoid leukemia and secondary papillary carcinoma of the thyroid. Case report

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the […]

High correlation between microbubble contrast-enhanced ultrasound, magnetic resonance and histopathology in the evaluation of hepatocellular carcinoma

DOI: 10.1590/S1679-45082013000400017

OBJECTIVES:To evaluate the efficacy of microbubble contrast ultrasound in diagnosis of hepatocellular carcinoma and to compare its results with those of magnetic resonance and histopathology.METHODS:A total of 29 patients suffering from chronic liver diseases and awaiting liver transplants at Hospital Israelita Albert Einstein were subject to magnetic resonance, microbubble contrast ultrasound, and excision liver biopsies.RESULTS:Excellent agreement between magnetic resonance and microbubble contrast ultrasound was observed in this study. There was moderate agreement between both imaging methods and histopathology results.CONCLUSION:Microbubble contrast […]

Coronary computed tomography angiography with 320-row detector and using the AIDR-3D: initial experience

Coronary computed tomography angiography (coronary CTA) is a powerful non-invasive imaging method to evaluate coronary artery disease. Nowadays, coronary CTA estimated effective radiation dose can be dramatically reduced using state-of-the-art scanners, such as 320-row detector CT (320-CT), without changing coronary CTA diagnostic accuracy. To optimize and further reduce the radiation dose, new iterative reconstruction algorithms were released recently by several CT manufacturers, and now they are used routinely in coronary CTA. This paper presents our first experience using coronary CTA […]

ABSTRACT Objectives: To evaluate the use of magnetic resonance imaging in patients with β-thalassemia and to compare T2* magnetic resonance imaging results with serum ferritin levels and the redox active fraction of labile plasma iron. Methods: We have retrospectively evaluated 115 chronically transfused patients (65 women). We tested serum ferritin with chemiluminescence, fraction of labile plasma iron by cellular fluorescence and used T2* MRI to assess iron content in the heart, liver, and pancreas. Hepatic iron concentration was determined in […]

Perforated diverticulitis of the appendix: ultrasonographic diagnosis

ABSTRACT Appendiceal diverticulitis is an uncommon condition, mimicking appendicitis, but with greater risk of perforation and complications. Preoperative diagnosis is rare, but can be achieved by ultrasonography as identification of the diverticulum and classical signs of appendicitis. We report a case of ultrasonographic diagnosis of a perforated appendiceal diverticulitis in an adult male and discuss this condition.
