Three members of a family, father, daughter, and son, with the basal cell nevus syndrome are presented. A very unusual manifestation of widespread cyst-like osteolytic lesions in all the tubular bones was observed in the father, together with osteoblastic spotty osteopoikilotic lesions in the skull and the mandible of the same patient. Cyst-like osteolytic lesions have been described previously in this syndrome, mainly in the phalanges. We believe that such lesions can occur in any bone. 相似文献

Fahr syndrome is a rare condition mainly characterized by symmetric and bilateral calcification of basal ganglia and cerebellar nuclei. Herein, we report a case of a 67-year-old woman with a history of parathyroidectomy and Parkinsonism, who was admitted to hospital with suspected neuroinfection, and imaging features that were consistent with Fahr syndrome. The objective of this study is to teach clinicians about a neurologic illness that requires comprehensive medical and neurologic investigation due to the manifestations of lymphocytic meningitis might distract you from Fahr syndrome symptoms. 相似文献

Central-variant posterior reversible encephalopathy syndrome is an atypical subtype of posterior reversible encephalopathy syndrome that occurs during rapid fluctuations in blood pressure, leading to cerebrovascular autoregulatory failure and endothelial dysfunction. Few reports have described posterior reversible encephalopathy syndrome in infants. A 4-month-old girl, who was diagnosed a month before with hypoxic ischemic encephalopathy due to sudden cardiac arrest, showed persistent renovascular hypertension with a systolic blood pressure of 200 mmHg. Computed tomography of the head revealed a new-onset low-attenuation area in the bilateral basal ganglia, and computed tomography of the trunk revealed severe long-segment narrowing of the abdominal aorta encompassing the bilateral renal arteries. She was treated with antihypertensive drugs and peritoneal dialysis. Follow-up imaging after blood pressure stabilization showed resolution of the low-attenuation area in the bilateral basal ganglia. We diagnosed her basal ganglia lesions as central-variant posterior reversible encephalopathy syndrome. She suffered from neurological sequelae attributable to hypoxic ischemic encephalopathy but showed no evidence of basal ganglia dysfunction. Here, we report a case of infantile central-variant posterior reversible encephalopathy syndrome involving bilateral basal ganglia lesions with mid-aortic syndrome. The differential diagnosis of infantile symmetric bilateral basal ganglia lesions is broad and includes genetic, acquired metabolic or toxic, infectious, inflammatory, vascular, and neoplastic pathologies. Among them, central-variant posterior reversible encephalopathy syndrome is rare but important because neurological prognosis may be favorable, and specific treatment, such as administration of antihypertensive drugs or discontinuation of drugs that induce posterior reversible encephalopathy syndrome, is possible. 相似文献

Gorlin's syndrome (also known as basal cell nevus syndrome, Gorlin-Goltz syndrome, and nevoid basal cell carcinoma syndrome) is a rare, inherited disorder characterized by multiple basal-cell epitheliomas, intracranial calcification, keratocysts of the mandible, and unusual and striking skeletal abnormalities. We present the interesting case of a 45-year-old woman who was informed that she had fibrous dysplasia of the extremity at another institution before extensive radiological work-up showed a diffuse skeletal process. The skeletal abnormalities, in conjunction with the patient's history of multiple basal cell carcinomas, is consistent with the diagnosis of Gorlin's syndrome. We describe this unusual case of striking radiological and scintigraphic findings in a patient with Gorlin's syndrome. 相似文献

28 patients with definite, probable or phenotypic Marfan syndrome underwent manual and computerised measurement of their metacarpal indices. Two methods were used from among the several variations quoted in the literature, one involving the average length/width of metacarpals 2–5 (method I), and the other dividing the sum of the lengths by the sum of the widths of these metacarpals (method II). The two methods are not mathematically identical, and a statistically significant difference was noted between them. Only 50% of the children in each group had elevated metacarpal indices, making it a time-consuming method that is indicative only of the phenotype and can be found in normal individuals. It should therefore be considered an obsolete measurement in Marfan syndrome. 相似文献

Acute soft head syndrome is an extremely rare complication in children with sickle cell anemia. We present a 16-year old male patient known to have sickle cell anemia who presented to our emergency department with low grade fever, headache, skull pain and swelling. Magnetic Resonance of the brain was done demonstrating subgaleal collections overlying calvarial signal abnormalities. The combination of clinical and radiological findings were indicative of acute soft head syndrome. Acute soft head syndrome is a rare complication in children with sickle cell anemia and the pathophysiology is related to osteonecrosis and bone infarcts of the calvarium as well as secondary reactive sub-galeal collections. Treatment includes conservative management with intravenous fluids and analgesics, in addition, our patient was treated with antibiotics since differentiation clinically and by imaging can be challenging. Acute soft head syndrome should be considered in the differential diagnosis of headache and skull swelling in children with sickle cell anemia. 相似文献

For the time being, COVID-19 has been endemic and presents a varied neurological picture. Moreover, one of the remarkable neurological pictures is posterior reversible encephalopathy. It is a neurotoxic state which is considered a rare manifestation; however, it is essential to recognize. It originates from the disturbance of the blood-brain barrier which causes vasogenic edema and most commonly occurred in the parieto-occipital regions. Thus, we presented a case of a patient diagnosed with COVID-19 infection with posterior reversible encephalopathy syndrome (PRES) as shown at the brain MRI examination. It was categorized as a form of brain disorder in COVID-19. 相似文献

Summary We report characteristic and morphometric changes of cranial computed tomography (CT) with increasing age in 56 patients with Down's syndrome aged from 0 month to 37 years. Patients were compared with 142 normal controls aged 0 to 59 years. Width of ventricles, Sylvian fissures, posterior fossa, pons and cisterna magna were measured on CT. The incidences of the cavum septi pellucidi, cavum vergae and cavum veli interpositi and high density in the basal ganglia were examined. There was high incidence (10.7%) of bilateral calcification of basal ganglia in Down's syndrome, although that of pineal body and choroid plexus calcification was similar in Down's syndrome and controls. Basal ganglia calcification is more frequently seen in young Down's syndrome and may be related to the premature aging characteristic of Down's syndrome. The CT in Down's syndrome showed relatively small posterior fossa, small cerebellum, small brain stem and relatively large Sylvian fissures in those under one year of age. There was a high frequency of midline cava and large cisterna magna. There were no significant atrophic changes on CT except after the fifth decade comparing with controls. 相似文献

Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome presents with the features of herpes simplex encephalitis (HSE), which is rare and has been described in only a few case reports. Our case describes a 17-year-old female with no significant previous medical history presenting with an acute onset of fever, headache, and epilepsy, similar to HSE. Computed tomography of the brain showed bilateral basal ganglia calcification. Magnetic resonance imaging demonstrated gyriform restricted diffusion with T2-weighted images prolongation. Further investigation showed elevated blood lactate concentration at rest. Hence, MELAS was suspected and the diagnosis was confirmed by the presence of a nucleotide 3243 A→G mutation in the mitochondrial DNA. The clinical presentation and imaging studies of MELAS are variable and may mimic those of HSE. Infection may have also precipitated MELAS manifestation in this patient. Laboratory features, such as elevated lactate, basal ganglia calcification, and gyriform restricted diffusion may be helpful in identifying patients with MELAS. 相似文献

BACKGROUND AND PURPOSE: Medulloblastoma is one of the most common posterior fossa tumors to occur in children. Our purpose was to document the frequency, location, and time of occurrence of intracranial calcifications in cranial CT studies of children with medulloblastoma. METHODS: We retrospectively reviewed cranial CT studies of 56 patients diagnosed with medulloblastoma from 1983 through 1997 for the presence of intracranial calcifications. The findings were compared with 159 cranial CT studies of patients who were evaluated in the emergency department (control group). Thirty-two patients with medulloblastoma without shunts were compared with 118 patients from the control group without shunts. Similarly, 24 patients with medulloblastoma with shunts were compared with 41 patients from the control group with shunts. RESULTS: Overall, three (9%) patients with medulloblastoma without shunts, four (16%) patients with medulloblastoma with shunts, and four (10%) patients from the control group with shunts had falx calcification. Only the two children carrying the diagnoses of medulloblastoma and nevoid basal cell carcinoma syndrome, however, had calcification of the falx cerebri shown on the cranial CT scans obtained during the peridiagnostic period. Both were diagnosed with medulloblastoma before the age of 3 years and later developed jaw cysts and multiple basal cell carcinomas in the radiation field. CONCLUSION: Previous studies have shown that falx calcification is a major component of nevoid basal cell carcinoma syndrome. Our two cases illustrate the importance of considering the diagnosis of nevoid basal cell carcinoma syndrome when falx calcification is present in young patients with medulloblastoma. If the concomitant diagnosis of nevoid basal cell carcinoma syndrome is made, alternative types of therapy should be sought to minimize radiation therapy sequelae. 相似文献

Gorlin's syndrome (naevoid basal cell carcinoma) is an autosomal dominant tumor-predisposition syndrome, classically consists of multiple basal cell carcinomas of the skin, odontogenic keratocyst of the jaw, various skeletal abnormalities, and lamellar falx calcifications. Many associated lesions have been reported. We report a case of Gorlin's syndrome in a 22-year-old man in whom CT and MR images showed unusual findings of the thin corpus callosum and third ventricular cyst. We present a case of this syndrome with special emphasis on its unusual neuroradiological findings and radiological management. 相似文献

Moyamoya disease is an unusual occlusive cerebrovascular condition commonly seen in children, marked by stenosis of the internal carotid artery and circle of Willis, causing, cerebral ischemia. Moyamoya syndrome is a Moyamoya-like arteriopathy with risk factors including autoimmune disorders, thyroid disease, sickle cell disease, or Down syndrome. Trisomy 21 is a genetic disorder consistent with specific physical and behavioral characteristics, with intellectual impairment. We describe a rare case of Moyamoya syndrome manifesting as ischemic stroke in an adult with Down syndrome 相似文献

Dyke-Davidoff-Masson syndrome (DDMS) is an uncommon neurological disease defined as cerebral hemiatrophy with a contralateral motor deficit, facial asymmetry, and seizures. Classic imaging findings are cerebral hypoplasia, ventriculomegaly, paranasal sinus hyper-pneumatization, and compensatory osseous enlargement. The diagnosis of DDMS is based on the correlation between clinical and neuroimaging features. The management of DDMS is based on anticonvulsant medication with physiotherapy. We describe an unusual case of DDMS presented with frequent and persistent seizures. 相似文献

Gestational choriocarcinoma is a malignant trophoblastic tumor arising from any gestational event, even with a long latency period, generally in the reproductive female. It is associated with a high level of beta-human chorionic gonadotropin. Its primary site is usually the uterus but not all patients have a detectable lesion in this site. Regression of the primary tumor after it has metastasized is not uncommon, and one-third of cases manifest as complications of metastatic disease. In this report we present an uncommon case of gestational choriocarcinoma with lung, liver and jejunal metastases at the time of diagnosis without evidence of pelvic disease, in 34-year-old woman. The main points of interest of our case were the development of the ovarian hyperstimulation syndrome with massive multicystic ovarian enlargement induced by high level of beta-human chorionic gonadotropin and the bleeding of jejunal and liver metastases, due to the high vascularity of the tumor tissue, a condition known as “Choriocarcinoma Syndrome”. We will focus on the radiological findings of metastases, bleeding complications and ovarian hyperstimulation syndrome. 相似文献
