Persistência hiperplástica do vítreo primitivo: avalia??o por métodos de imagem
Jacob, Beatriz Mahmud;Teixeira, Kim-Ir-Sen Santos;Figueirêdo, Sizenildo da Silva;Nóbrega, Bruno Barcelos da;

Abstract: persistent hyperplastic primary vitreous (phpv) is a congenital developmental anomaly of the eye that primarily affects premature infants. phpv results from failure of regression of the embryogenic primary vitreous and hyaloid vasculature, and proliferation of connective tissue. three types of phpv may be found: anterior, posterior and a combination of anterior and posterior. the clinical findings include leukocoria (white pupillary reflex) and microphthalmic eye. this anomaly is usually unilateral and unassociated with other systemic findings. the differential diagnosis between phpv and other ocular diseases may be difficult due to similar features such as leukocoria, detached retina, retinal folds and cataract. other diseases with similar features include retinoblastoma, isolated congenital cataract, retinopathy of prematurity and pseudogliomas or leukocorias. direct visualization of the remnants of the fetal hyaloid vascular system offers the best evidence of phpv. however, diagnosis using the ophthalmoscope is sometimes impossible because of opaque tissues. in this circumstance an indirect visualization by ultrasound, computed tomography or magnetic resonance imaging may be useful. these imaging methods provide valuable information for the differentiation from other diseases, particularly retinoblastoma. the authors present a review of the literature and an iconographic study of the imaging findings in patients with phpv.

Abstract: Persistência hiperplásica do vítreo primitivo (PHVP) é um desenvolvimento anormal, afetando crian as, resultante da falha de regress o do vítreo primitivo e dos vasos hialóides, com prolifera o de tecido conectivo. A PHVP pode ter três varia es: uma anterior, outra posterior e uma terceira com a combina o das duas. Clinicamente manifesta-se como leucocoria (reflexo branco pupilar) em um olho de dimens es reduzidas. Esta anomalia é usualmente unilateral e n o associada com outros achados sistêmicos. Leucocoria, descolamento de retina, pregas retinianas e catarata podem confundir PHVP com outras afec es oculares que têm achados semelhantes. Retinoblastoma, catarata congênita, retinopatia da prematuridade e pseudogliomas s o doen as com achados semelhantes aos da PHVP. A visualiza o direta dos remanescentes do sistema vascular hialóide fetal é a melhor evidência da les o presente, se n o fosse, muitas vezes impossivel, à fundoscopia, devido à opacidade do tecido. Nestes casos, a visualiza o indireta, por meio de ultra-sonografia, tomografia computadorizada e ressonancia magnética, fornece o diagnóstico. As imagens obtidas por estes métodos proporcionam, ainda, informa es e diagnóstico diferencial com outras doen as, particularmente com o retinoblastoma. Os autores fazem uma revis o na literatura e apresentam um estudo iconográfico das imagens e achados da PHVP.
Microlitíase alveolar pulmonar: achados na tomografia computadorizada de alta resolu??o do tórax em 10 pacientes
Marchiori, Edson;Gon?alves, Carolina Marinho;Escuissato, Dante Luiz;Teixeira, Kim-Ir-Sen Santos;Rodrigues, Rosana;Barreto, Miriam Menna;Esteves, Mauro;

Abstract: objective: to present the high-resolution computed tomography (hrct) findings of pulmonary alveolar microlithiasis. methods: the hrct scans of 10 adult patients (seven females and three males; mean age, 38.7 years) were retrospectively analyzed. the films were studied independently by two radiologists. results: the most common tomographic findings were ground-glass attenuation and linear subpleural calcifications, which were seen in 90% of the patients. other relevant findings were small parenchymal nodules, calcification along the interlobular septa, nodular cissures, subpleural nodules, subpleural cysts, dense consolidations, and a mosaic pattern of attenuation. conclusions: the hrct findings presented by individuals with pulmonary alveolar microlithiasis are distinct. in most cases, such findings can form the basis of the diagnosis, eliminating the need to perform a lung biopsy.

Abstract: we report a case of a 2 years and 8 months-old child with the recessive form of craniometaphyseal dysplasia. clinical and radiological features as well as the main differential diagnosis are discussed and compared with data from a brief literature review.

Abstract: callosal dysgenesis is a malformation of the corpus callosum with origins in the embryogenesis of the telencephalon. we reviewed the computed tomography and magnetic resonance imaging findings of 11 patients with callosal dysgenesis and one patient with normal corpus callosum associated with a lipoma. the patients were divided into three distinct groups: total agenesis (three patients), partial agenesis (six patients) and hypoplasia (two patients). associated abnormalities were observed in nine patients, including chiari ii malformation (one patient), schizencephaly (one patient), interhemispheric cyst (two patients), dandy-walker cyst (one patient), nodular heterotopy (one patient) and lipoma of the corpus callosum (four patients). this paper presents a review that may contribute to the diagnosis of these disorders.

Abstract: tracheobronchomegaly is a rare condition of uncertain etiology characterized by marked dilatation of the trachea and main bronchi, bronchiectasis and recurrent respiratory tract infections. clinical presentation is nonspecific and the diagnosis is usually made by imaging methods. we report a case of a patient with tracheobronchomegaly. diagnosis was confirmed by plain x-ray films and computed tomography of the chest.

Abstract: fibrovascular polyp of the esophagus is a rare, pedunculated, intraluminal, benign tumor. we describe a case of a patient with a fibrovascular polyp of the esophagus and discuss the esophagogram and computed tomography findings. due to the excellent correlation between pathology and imaging findings, computed tomography and magnetic resonance imaging are considered specific and useful in its diagnosis.

Abstract: hypertrophic pyloric stenosis is a common condition in infants with 2 - 12 weeks of postnatal life. the cause of this disease remains obscure. clinical diagnosis is based on the history of projectile, nonbilious vomiting, gastric hyperperistalsis and a palpable pyloric "tumor". the authors review the typical findings seen on upper gastrointestinal x-ray series and abdominal ultrasonography. the diagnostic criteria for hypertrophic pyloric stenosis are presented and the applications of these two methods are established on the basis of the current literature.

Abstract: fibrodysplasia ossificans progressiva is a rare hereditary connective tissue disease characterized by disseminated soft tissue ossification and congenital abnormality of the extremities. it is genetically inherited as a dominant trait with complete penetrance but variable expression. the onset takes place during childhood and the progressive involvement of the spine and proximal extremities leads to immobilization and articular deformity. we report a case of a 22-year-old male patient with typical symptoms of fibrodysplasia ossificans progressiva and discuss the new advances in the diagnosis and pathophysiology.

Abstract: sacroiliitis is a non-infectious inflammatory process involving the sacroiliac joint, and is a diagnostic criterion for seronegative spondyloarthropathies. imaging methods are of great value for confirming the diagnosis of this condition. the present study is a review of cases included in didactic files and in the literature to illustrate the anatomy, techniques, and main imaging findings in x-ray, computed tomography and magnetic resonance imaging for determining the diagnosis of sacroiliitis, also approaching main differential diagnoses.
