We report two patients with Robinow syndrome, review the published literature and stress the importance and limitations of radiographic examination in the diagnosis of this disorder, which shows extreme clinical and radiographic variability. The radiographic differential diagnosis of Robinow syndrome is discussed.
The authors report the case of a vertebromedullary hydatidosis revealed by medullar compression in a 40-year-old male patient. Magnetic resonance imaging showed lesions of the seventh and eighth dorsal vertebras, cystic lesions in the epidural space and in the perivertebral soft tissues. Surgical excision lead to clinical cure. Vertebromedullary hydatidosis is rare and severe. Modern techniques of imaging are very helpful for the diagnosis and the follow-up of patients after treatment.
Pachydermoperiostosis or primary hypertrophic osteoarthropathy is a benign genetically determined disease, manifested by finger clubbing, hypertrophic skin changes and periosteal bone formation. It is rarely reported and was for a long time misdiagnosed and confused with secondary hypertrophic osteoarthropathy. We present the imaging features in two cases and review the literature.
PURPOSE: The aim of this study was to report the MRI findings that can suggest a vaso-occlusive crisis in cases of febrile osseous pain in children suffering from sickle cell disease. MATERIALS AND METHODS: MRI (T1 and T2 weighted sequences and T1 weighted sequence with fat saturation before and after gadolinium injection) was performed in 10 children with sickle cell disease, presenting with febrile osseous pain. The diagnosis of vaso-occlusive crisis was made after fast improvement due to symptomatic treatment and negative bacteriological result. RESULTS: MRI was abnormal in all cases. A multifocal localisation was found in 2 cases. Bone marrow abnormalities were constant. In 10 cases, high T1 and T2 signal and metaphyso-diaphysial lesions were noted. Heterogeneous medullar enhancement with "ink stain" feature was constant. Early periosteal abnormalities were noted in 8 cases with inflammatory or stratified features. Cortical thinning was found in 1 case. Soft tissue abnormalities were observed in 5 cases with inflammatory features in 4. CONCLUSION: Multifocal synchronous localisation, medullar abnormalities resulting from hemoglobin degradation, heterogeneous enhancement, early periosteal abnormalities and associated soft tissues swelling are MRI findings suggesting acute vaso-occlusive disease.

Eagle's syndrome, also known as elongated styloid process, is an entity that may be the source of craniofacial and cervical pain. It is frequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of Oropharyngeal and Maxillofacial diseases. The paucity of information in the radiologic literature prompted this report.
We report a case of subchondral osteoid osteoma of the tarsal navicular bone. Osteoid osteomas are often located in the foot, mainly in the talus. This is the first report in the literature of a tarsal navicular bone localization. Diagnosis was difficult and established late due to misleading clinical presentation simulating mediotarsal arthritis.
Cystic teratoma of the diaphragm is a rare, generally asymptomatic, disease. We report a case which was disclosed by the development of fever and pain in the left hypochondria. Imaging ruled out surgical emergency and led to the diagnosis, describing the relations of the tumor.
Osler-Weber-Rendu disease is a hereditary vascular disease with multiple manifestations. The liver is involved rarely. Vascular abnormalities include telangiectasis and arteriovenous fistulas, sometimes associated with fibrosis and cirrhosis. Hepatic arteriovenous shunting may include secondary portal hypertension, reduced liver function and high cardiac output. Two cases of Osler-Weber-Rendu disease with extensive hepatic arteriovenous fistulation were described in detail and we report on their clinical features. In the first patient, treatment was symptomatic since liver transplantation is not indicated because the patient was asymptomatic. Embolization treatment of hepatic arteries was indicated in the second patient because he had biliary disease and recurrent cholangitis secondary to vasculo-biliary shunts. Therapy with arterial embolization, banding, or ligature of hepatic arteries is still limited and provides unsatisfactory long-term results. Liver transplantation offers now another therapeutic option for patients with intrahepatic high shunting and secondary pulmonary hypertension.
We report the eighteenth case of spontaneous rupture of the upper urinary tract in a pregnant woman (age = 24 years, term = 28 weeks). Sonography showed an anechogenic collection in the left perirenal area. Computed tomography confirmed the diagnosis of rupture. No cause could be determined due to the lack of an urography in post-partum. The first treatment was a double echo-guided percutaneous drainage. The pregnancy was completed to term with normal vaginal delivery of a live infant. Sonography showed complete cure.
Peritonitis can result from many causes. We report a case caused by a renal abscess which contaminated the abdominal cavity. A 30-year-old patient was referred with suspected ruptured ectopic pregnancy with signs of peritoneal flooding. The culdocentesis was positive and returned frank pus. Endoscopic exploration with an open laparoscope revealed that the infection did not originate from a gynecological infection but did not identify the exact origin. Laparotomy was performed and revealed a splenic abscess and a subphrenic peritoneal breach releasing a purulent liquid. Splenectomy and abdominal lavage with draining was performed. A post-operative pyelourogram showed a silent kidney with multiple coralliform lithiases. Interventional sonography allowed drainage of a retroperitoneal collection. The post-operative period was uneventful. Left nephrectomy was later performed. Only rare cases of ruptured pyonephrosis leading to peritonitis have been reported, usually with poor prognosis.
We report an exceptional case of pyeloureteral malformation which occurred on a single kidney. The malformation was discovered at 32 week of gestation when ultrasonography showed hydronephrosis. Initial treatment consisted in echoguided drainage. The patient gave birth to a live infant via normal vaginal delivery and then underwent resection of the pyeloureteral malformation with anastomotic reconstruction of the upper urinary tract.

Four patients with solitary or multiple splenic fluid collections were treated by ultrasound guided percutaneous needle aspiration and drainage. There was one unilocular abscess, three infected hematomas, one large hematoma and a complex lesion with locular and perisplenic involvement. Percutaneous drainage and antibiotics were curative in one patient. Splenectomy was performed because of persistent fever and drainage of pus after 15 days in one case and recurrence of hematoma in an other case. Solitary fluid collection can be effectively treated by ultrasound or computed tomography guided percutaneous drainage. Hematoma represents a cause of failure of percutaneous drainage.
The authors present a case of left unilobar Caroli's disease in a 83-year-old-woman associated with a Jaccoud's arthropathy of the hands. The role of repeated episodes of cholangitis and genetic tendency is discussed...
