Spinal Cavernomas

Case presentation: A 10-year-old male patient was admitted due to posterior cervicalgia, vomiting and progressive generalized weakness. Physical examination showed difficulty in ambulation and tetraparesis. Magnetic resonance imaging (MRI) of the cervical medulla enhanced by the contrast agent, gadolinium, showed a poorly contrasted mass with a hemorrhagic center. We undertook a posterior cervicotomy (C1-C3). Post-operative evolution was satisfactory with complete regression of the deficits 90 days after surgery. Control MRI at intervals of 1 and 4 years confirmed absence of the tumor. Discussion: Cavernomas are vascular malformations, consisting of coarsely dilated vascular channels and coated by a single layer of endothelial cells, devoid of endothelium and myothelium. They represent only 5-12% of all vascular pathologies of the medulla, with only 10% affecting the pediatric population. There are only thirty cases of pediatric intramedullary spinal cavernomas in the literature, with predominance among males (2.1:1). Thoracic and cervical spinal cavernomas consist in 55% and 45% of the cases, respectively. In six cases (20%) cavernomatous lesions were associated with synchronic intracranial cavernoma. Among the reported cases, only one had poor evolution after surgery, whereas six patients persisted with prior symptoms. Conclusion: Spinal intramedullary cavernomas are rare entities, especially in the pediatric population, and are treated with surgery which improves prior neurologic deficits, besides preventing rebleeding

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.

Meningiomas are known to be more common in females than males. They are also known in rare cases to grow in size during pregnancy, which can complicate its management. We describe a 31-year-old Caucasian woman who presented with blurring of her vision and diplopia during the third trimester of her pregnancy. Magnetic resonance imaging (MRI) showed a small left cavernous sinus meningioma. The patient was treated conservatively until her uncomplicated delivery. A postpartum MRI scan showed complete regression of the suspected meningioma. Currently the patient is contemplating a further pregnancy.

Objective.Magnetic resonance imaging (MRI) is playing an increasingly important role in the diagnosis and followup of juvenile idiopathic arthritis (JIA). Carpal depressions are commonly observed in healthy children and in patients with JIA. The aim of our study was to further characterize these depressions in patients with JIA.Methods.A total of 29 MRI wrist examinations were analyzed. Depressions were classified according to morphology as either tubular or focal. Features including the presence of a vessel related to the depression, evidence of synovitis, bone marrow edema, or loss of joint space on a radiograph taken on the same day were recorded for each depression.Results.A total of 173 depressions were identified in 145 carpal bones. Forty percent were capitate depressions. A third were focal depressions and two-thirds were tubular. About 10% of tubular depressions and 30% of focal depressions were associated with features suggesting true erosions, with the remainder likely to represent vascular channels and normal variants.Conclusion.Radiologists and clinicians should undertake caution when assessing carpal depressions on MRI because the vast majority are likely to represent normal variants.

Aortic Dissections

Spinal cord ischemia most often presents as an anterior spinal artery syndrome and involves watershed regions of the spinal cord. The clinical presentation and etiologies can be heterogeneous, but cord infarcts are typically the result of aortic surgeries, systemic hypotension, vertebral artery and aortic dissections, embolus, or vascular malformations. Given that it is a rare entity, involving symptoms that can progress over minutes to hours, a diagnosis is often delayed until after conventional windows for revascularization, including thrombolysis, have passed. Magnetic resonance imaging (MRI) is usually required to confirm the diagnosis.

Purpose:To evaluate the prevalence of nonlesional focal epilepsy in an adult epilepsy clinic and its refractoriness to antiepileptic drug therapy.Background:Focal epilepsy is frequently, but not always, associated with structural epileptogenic lesions identifiable on magnetic resonance imaging (MRI).Methods:We analyzed the data from all patients evaluated at an adult epilepsy clinic from January 2002 to December 2011. Clinical and paraclinical findings were used to diagnose focal epilepsy. Magnetic resonance imaging were reviewed and classified as normal, with an epileptogenic lesion, or with a lesion of unclear epileptogenicity. Epileptogenic lesions were further categorized as tumours, vascular malformations, gliosis (including hippocampal atrophy/sclerosis), and malformations of cortical development. Our study group included patients with no lesions on MRI. Pharmacoresistance of patients with nonlesional focal epilepsy was assessed using the ILAE and Perucca's criterias.Results:Out of 1521 patients evaluated (mean age 44 years; range 14-93 years), 843 had focal epilepsy. Magnetic resonance imaging data, available for 806 (96%) subjects, showed epileptogenic lesions in 65%, no obvious epileptogenic lesions in 31% and lesions of unclear epileptogenicity in 4%. Magnetic resonance imaging-identified lesions included gliosis due to an acquired insult (52% including 17% of hippocampal atrophy or sclerosis), tumours (29%), vascular malformations (16%) and malformations of cortical development (10%). Fifty-two percent of nonlesional focal epileptic patients were drug-refractory.Conclusion:In a tertiary epilepsy clinic, close to a third of patients with focal epilepsy were found to be nonlesional, half of which were drug-resistant.

Abstract Background Lipomas are often small tumors and rarely reach a size larger than 2 cm. Vulvar lipoma is a rare tumor localization, and only a few cases have been reported. It is important to distinguish lipomas from other vulvar masses like liposarcomas, Nuck canal cyst, Bartholin’s cyst, and inguinal hernias. Case presentation We report on a case of a 43-year-old woman who presented with a giant left vulvar mass and discuss the magnetic resonance imaging (MRI) results. Conclusions MRI is useful in evaluating vulvar lipomas and differentiating them from other vulvar pathologies.

Brainstem Cavernous Malformation

AbstractCavernous malformation (CM) of the central nervous system (CNS) are acquired or developmental vascular malformations that represent the 5% to 15% of all vascular malformations of the CNS. Eighty to ninety percent of CM are supratentorial, 15% infratentorial, and 5% occur in the spinal cord. The subset of brainstem malformation presents as a very difficult paradigm for treating clinicians. The widespread use of magnetic resonance imaging (MRI) has increased the recognition of this disease. Clinical presentation, pathophysiology and treatment are discussed in this article.

Intrathoracic endometriosis is classified into pleurodiaphragmatic endometriosis and bronchopulmonary endometriosis. Bronchopulmonary endometriosis is rare. Computed tomography (CT) findings of bronchopulmonary endometriosis are lung nodules, with or without cavities, or surrounding ground-glass opacities. Features vary with menstrual status. Recently, the usefulness of magnetic resonance imaging (MRI) was reported for diagnosis of intrathoracic endometriosis, but most published reports were about pleurodiaphragmatic endometriosis. We present CT and MRI findings of bronchopulmonary endometriosis in the left lung that showed a gradually enlarging nodule with enhancing area.

Angiographic Examination

Because digital subtraction angiography (DSA) is not an ideal angiographic examination for moyamoya disease in the pediatric population, magnetic resonance angiography (MRA) provides a noninvasive contrast-free angiographic examination; whereas magnetic resonance imaging (MRI) provides superior spatial resolution and soft-tissue contrast for lesion assessment. Ninety patients with moyamoya disease were examined by MRI and DSA to assess the distribution of lesions and their diagnostic agreement between modalities. MRI examination revealed 439 lesions. Punctate lesions were the most abundant, followed by patchy lesions. These lesions generally covered a smaller area than the abnormal-vascular corresponding brain parenchyma. Steno-occlusive changes at bilateral anterior, medial, and posterior cerebral arteries were identified by MRA and DSA. MRI showed moderate agreement in identifying lesions after steno-occlusive changes in anterior and medial cerebral arteries, and good agreement in posterior cerebral arteries; 6% to 11% of cases were misdiagnosed by MRA.
