Multicentric Nidus

Osteoid osteoma (OO) is a common benign tumor of the bone and is typically treated by thermal ablation with computed tomography (CT) guidance. Only a few cases of multicentric OO have been described. We here report the case of an 11-year-old boy with multicentric OO of the right femur treated with laser ablation under open high-field MRI guidance. The steps of the interventional MRI procedure are described, discussing the benefits and disadvantages of MRI versus CT guidance especially with regard to younger patients.

Abstract Backgroundcardiac myxoma is a common benign tumor of the heart. It can have any presentation such as mitral stenosis, embolization. The best treatment is surgical resection.Case presentationA 30-year-old man presented with 2-days of right renal colic and chest tightness, dyspnea. He was diagnosed as renal infarction through ultrasound in another hospital and received some analgesic drugs. But the symptoms didn’t resolved and he came to our ICU(Intensive Care Medicine). We performed the ultrasonography and found a mass in the right atrium computed tomography angiography cofirmed it, and it was cross-valve growth, irregular shape, and slight enhancement of the enhanced edge, consider myxoma. Multiple non-reinforced areas were seen in the right renal cortex and medulla, right renal artery embolization, right renal infarction might be considered. The patient was taken to the operating room for emergent myxoma resection, renal artery thrombectomy.ConclusionMyxomas should be in differential diagnosis in patient present with thromboembolism. Early diagnosis and surgical are crucial treatment in deal with myxoma.

Osteoid osteoma is a relatively common benign tumor of bone which occurs most often in adolescents and young adults. The pattern of the pain with its characteristic response to aspirin and the roentgenographic findings make the clinical diagnosis easy and virtually certain. An example is presented to help the pediatrician become familiar with the tumor and its diagnosis.

Renal angiomyolipoma (AML) is the most common benign tumor of the kidney. There are few case reports in the literature, especially those occurring during pregnancy. We, at this moment, are reporting a case of a 32-year-old female patient who presented at 21 weeks of gestation with right-sided flank pain, chills, macroscopic hematuria, and vomiting. On examination, she was hemodynamically stable, with no fever. Renal ultrasound showed the presence of a hyperechogenic vascularized fatty tissue on the right kidney, measuring 7.4 x 5.1 x 6.2 cms, with minimal pelvicalyceal dilatation. The MRI opted for an angiomyolipoma. Discharged home at day 4 of admission, the patient’s continued the remaining weeks of her pregnancy uneventfully, until 37 weeks. She delivered her baby vaginally with no further complications during pregnancy or in the post-partum period.In conclusion, due to the insufficient data in the literature supporting the management of patients with AML, the individualization of the treatment is an essential strategy.

A hallmark of brain injury from infection, vascular, neurodegenerative, and other disorders is the development of gliosis, which can be detected by magnetic resonance imaging (MRI). In rodent models of diet-induced obesity (DIO), high-fat diet (HFD) consumption rapidly induces inflammation and gliosis in energy-regulating regions of the mediobasal hypothalamus (MBH), and recently we reported MRI findings suggestive of MBH gliosis in obese humans. Thus, noninvasive imaging may obviate the need to assess MBH gliosis using histopathological end points, an obvious limitation to human studies. To investigate whether quantitative MRI is a valid tool with which to measure MBH gliosis, we performed analyses, including measurement of T2relaxation time from high-field MR brain imaging of mice fed HFD and chow-fed controls. Mean bilateral T2relaxation time was prolonged significantly in the MBH, but not in the thalamus or cortex, of HFD-fed mice compared with chow-fed controls. Histological analysis confirmed evidence of increased astrocytosis and microglial accumulation in the MBH of HFD-fed mice compared with controls, and T2relaxation times in the right MBH correlated positively with mean intensity of glial fibrillary acidic protein staining (a marker of astrocytes) in HFD-fed animals. Our findings indicate that T2relaxation time obtained from high-field MRI is a useful noninvasive measurement of HFD-induced gliosis in the mouse hypothalamus with potential for translation to human studies.

Osteoid osteoma is a benign tumor that accounts for roughly 10-12% of all benign bone forming tumors. This tumor generally occurs within the first three decades of life and occurs more commonly in males. This lesion is painful and is generally worse at night and has relief of symptoms with the use of NSAIDs. Osteoid osteoma is characterized by the production of osteoid surrounded by a rim of sclerotic bone. These lesions most commonly occur in long bones such as the proximal femur, however they can occur anywhere. Rarely, as with our patient, have these lesions been reported in the acetabulum.
