Manifestações extrapulmonares da paracoccidioidomicose

The authors present a review and iconographic study of patients with disseminated paracoccidioidomycosis, including the main radiographic findings seen in the central nervous system, adrenal glands, osteoarticular system, lymph nodes and digestive tract. Imaging diagnostic methods have allowed a more precise approach of these patients due to their high sensitivity in detecting lesions, even in asymptomatic patients. In most cases these abnormalities are unspecific, simulating either neoplasic or chronic infectious lesions, and sometimes difficult to distinguish from tuberculosis. Although these findings are nonspecific and only the mycologic and histologic fungus demonstration can confirm the diagnosis, they may suggest a presumptive one, when these imaging findings are considered in an appropriate clinical and epidemiological setting.

Fibrodisplasia ossificante progressiva: relato de caso e achados radiográficos

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.

Traqueobroncomegalia (síndrome de Mounier-Kuhn): relato de caso e revisão da literatura

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.

Caracterização radiográfica das manifestações esofagogastrointestinais da doença de Chagas

. A caracterizacao radiolo-gica baseia-se predominantemente nas cha-madas “megaformacoes”.Disfagia, regurgitacao, dor esofagianaespontânea, odinofagia, pirose, obstipacaointestinal, desnutricao, sialose com hiper-trofia das glândulas salivares e manifesta-coes pulmonares sao as mais usuais apre-sentacoes clinicas relacionadas ao megae-sofago

Querubismo: relato de caso e revisão da literatura com aspectos imaginológicos

Cherubim is a non-neoplastic hereditary bone disease characterized by bilateral, painless enlargements of the mandible and maxilla in children, producing the cherubic appearance. Cherubism may appear as an isolated case or in members of the same family. We report the case of a girl without familial history of cherubism who presented expansile osteolytic lesions in the mandible and maxilla, demonstrated by radiological exams.

Persistência hiperplástica do vítreo primitivo: avaliação por métodos de imagem

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.

Displasia craniometafisária: relato de caso

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.

Doença cística medular do rim: relato de um caso diagnosticado por ultra-sonografia e tomografia computadorizada

The terms medullary cystic disease, juvenile nephronophthisis or medullary cystic disease complex refer to a group of similar diseases in which the basic pathological abnormality is progressive renal tubular atrophy with secondary glomerular sclerosis and medullary cystic formation. Medullary cystic disease is an important cause of renal failure in adolescent patients. Imaging methods play a primary role in the diagnosis of these diseases. Cysts are characteristically seen in the renal medulla and corticomedullary junction whereas kidneys may be of normal to small size. In this article we present the ultrasonography and computed tomography findings of a female adolescent patient with characteristic clinical picture of medullary cystic disease.

Pólipo fibrovascular do esôfago: relato de caso e revisão da literatura

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.
