Ureteroceles are cystic dilations of the intravesical submucosal ureter. Most cases are associated with complete ureteral and renal duplication, and association with ureterohydronephrosis is frequent. The authors describe the 4 cases of fetal ureterocele diagnosed from March 2008 to March 2012. Mean gestational age at diagnosis was 23 weeks (16-34 weeks). One of 4 cases progressed to severe hydronephrosis with megacystis and was referred to a Fetal Medicine Center for fetoscopy and laser ureterocelotomy. The remaining 3 cases did not need fetal therapy. Mean gestational age at delivery was 37 weeks. One case abandoned follow-up; 2 children were submitted to cystoscopic ureterocele incision and the child submitted to fetal therapy needed heminephrectomy due to recurrent urinary tract infections. In those 3 cases renal function was preserved. When a fetal ureterocele is diagnosed, close sonographic surveillance should be offered to monitor the possible urinary tract obstruction and assess the need for prenatal intervention. Fetal diagnosis is important to program the timing of delivery and postnatal care.

Septic pelvic thrombophlebitis is a rare puerperal complication. It is an important differential diagnosis of postpartum fever and abdominal pain and although the condition is well known its diagnosis can be challenging. We report a case of a 41-year-old woman with fever and right abdominal pain three days after an uncomplicated caesarean delivery. Clinical, laboratory and imaging exams were unremarkable and the patient was treated for endometritis. In the absence of improvement despite an antibiotic adjustment, a clinical diagnosis of septic pelvic thrombophlebitis was made, and the patient presented a good response to anticoagulation in conjunction with broad-spectrum antibiotic therapy.

The best clinical approach to a fetal ovarian cyst is controversial. In this small series, three of the five cysts regressed spontaneously, including a hemorrhagic one. Once a fetal ovarian cyst is diagnosed, ultrasonographic monitoring should be provided in order to identify complications and define the best therapeutic approach.

(1):135-137 RESUMOA existência de uma gravidez gemelar bicoriónica com uma mola hidatiforme completa e um co-gémeo viável é um evento raro, sendo o diagnóstico habitualmente realizado no segundo trimestre. Pode associar-se a tirotoxicose, pré-eclâmpsia, hemorragia vaginal, doença persistente do trofoblasto e morte fetal. Os autores descrevem o caso de uma grávida com hemorragia do primeiro trimestre. As imagens ecográficas foram interpretadas como uma gravidez gemelar bicoriónica com um embrião vivo e outra placenta com imagem de descolamento. Às 16 semanas visualizou-se um feto vivo com placenta posterior e uma massa vacuolada anterior, vascularizada. Perante a hipótese de doença do trofoblasto o casal optou pela interrupção da gravidez. O exame anatomo-patológico confirmou o diagnóstico. Perante a raridade desta entidade clínica, é necessário um elevado índice de suspeição para estabelecer o seu diagnóstico ecográfico. Apesar de estarem descritos casos com um bom desfecho materno e neonatal, a decisão de continuação da gravidez deve ser tomada pelos progenitores.

The diagnosis is challenging, and is normally achieved only at second trimester. It may be associated with thyrotoxicosis, vaginal bleeding, preeclampsia, fetal death or persistent throphoblastic disease. The authors describe the case of a pregnant woman presenting with first trimester bleeding. Ultrasound revealed a twin pregnancy with a viable twin and another placenta apparently detached. At 16 gestational weeks ultrasound revealed a live fetus with a normal placenta and a separate vacuolated and vascularized mass. Facing the hypothesis of gestational trophoblastic disease, the couple chose pregnancy interruption. Given the rarity of this situation, a high index of suspicion is needed to achieve the diagnosis. Despite the existence of case reports with good fetal and maternal outcome, the decision of pregnancy continuation should be made by the informed parents.

INTRODUÇÃOA doença trofoblástica gestacional define-se como uma doença proliferativa das células do trofoblasto resultantes de um processo de fertilização aberrante. As doenças do trofoblasto mais frequentes são a mola hidatiforme completa, caracterizada por edema generalizado do tecido vilositá-rio, hiperplasia trofoblástica difusa, sem tecido embrionário presente, e a mola hidatiforme parcial, caracterizada por alterações placentárias hidatiformes focais e presença de embrião, habitualmente triplóide, com múltiplas malformações.1 Estima-se que a incidência de mola hidatiforme seja de 1 para 1 000, embora se verifiquem diferenças geográ-ficas importantes, com uma maior incidência nos países asiáticos e da América do Sul.1 Esta patologia é considerada pré-maligna, pelo que a interrupção da gravidez é a regra assim que se estabelece o di...
