A Case of Diastrophic Dysplasia Associated With Mega Cysterna Magna

Abstract

Skeletal dysplasias comprise a large group of hereditary disorders characterized by abnormal growth, short stature and malformations and deformations of bone and cartilage. Diastrophic dysplasia is a skeletal disorder characterized by short stature, foot and spinal deformities, hitchhiker's thumb and ear abnormalities. Internal organs develop normally. The physical examination of the newborn referred to our hospital for multiple abnormalities revealed a poor general condition with cyanosis, disproportionate short stature, large front fontanel, short neck, misshapen upper ear and ‘cauliflower' deformity, cleft palate, hitchhiker's thumb, long and slim fingers except the thumb, proximally located toes, flexion contractures in the large joints, bilateral talipes equinovarus and left scrotal hernia. Mega cysterna magna was demonstrated in the posterior fossa in the cranial tomography. With these clinical and radiological findings, the newborn was diagnosed as diastrophic dysplasia. The infant was discharged on day 19 after genetic counseling to the family and was to be followed up by the newborn outpatient clinic. Turkish Başlık: Mega Sisterna Magna ile Seyreden Bir Diyastrofik Displazi Olgusu Anahtar Kelimeler: Yenidoğan; diastrofik displazi; mega sisterna magna; otostopçu başparmağı İskelet displazileri boy kısalığı, kemik ve kıkırdak malformasyon ve deformasyonları ile karakterize heterojen bir grup hastalığı kapsar. Diyastrofik displazi (DTD) kulak anomalileri, ayak ve spinal deformiteler, “otostopçu başparmağı” ve kısa boy ile karakterize bir hastalıktır. İç organ tutulumu yoktur. Multipl anomalilerinin olması nedeniyle kliniğimize sevk edilen yenidoğanın fizik muayenede; genel durum kötü, renk siyanotikti, orantısız boy kısalığı, geniş ön fontanel, kısa boyun, düşük kulak, kulak kepçesinde “karnı bahar” deformitesi, yarık damak, otostopçu başparmağı, başparmak dışında diğer el parmaklarında incelik ve uzunluk, proksimal yerleşimli ayak başparmağı, büyük eklemlerde fleksiyon kontraktürleri, iki taraflı talipes ekinovarus ve sol skrotal herni olduğu belirlendi. Kraniyal tomografide, posterior fossada mega sisterna magna tespit edildi. Bu klinik ve radyolojik bulgularla olguya DTD tanısı kondu. On dokuzuncu günde yenidoğan polikliniğinden takip edilmek üzere, aileye genetik danışmanlık verilerek taburcu edildi.
