AbstractA case of a rare and unusual variant of neurofibroma, diffuse neurofibroma (paraneurofibroma), in a young patient is presented. The clinical, radiological and histopathological features of this case are reported. The magnetic resonance imaging (MRI) features of the diffuse neurofibroma are comparable with those described in other neurofibromas.

Myxoid (metaplastic) meningioma is the rarest WHO grade 1 meningioma, and its histological characteristics are useful in diagnostics. We present the case report of a myxoid (metaplastic) meningioma in a 44-year-old woman to highlight the important histological features and observations that are critical for making an accurate diagnosis. We report a rare myxoid meningioma using magnetic resonance imaging (MRI) images and its histopathological features.

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.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Primary extradural mesenchymal chondrosarcoma (MCS) is a very rare intraspinal tumor. Proper clinical evaluation with magnetic resonance imaging (MRI) followed by biopsy of the mass can confirm the diagnosis. Since MCS has a high tendency of recurrence and metastasis, the prognosis is guarded. We report a 52 years old male with primary extradural MCS in the lumbosacral region (L5-S3). Subtotal excision and biopsy were performed which confirmed the diagnosis. The patient received post excisional radiotherapy but expired after four months. Though rare, this tumor should be kept in differentials which helps in early diagnosis and thus can be treated with radical excision of the mass along with postoperative radiotherapy.

Abstract Many advances have been made in the imaging diagnosis and in the histopathological evaluation of HCC. However, the classic imaging and histopathological features of HCC are still inadequate to define patient’s prognosis. We aimed to find the link between new proposed morphovascular patterns of hepatocellular carcinoma (HCC) and magnetic resonance imaging (MRI) features to identify pre-operatory markers of biologically aggressive HCC. Thirty-nine liver nodules in 22 patients were consecutively identified. Histopathological analysis and immunohistochemistry for CD34 and Nestin were performed to identify the four different HCC morphovascular patterns. MRI was performed using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid. Three out of four morphovascular HCC patterns showed peculiar MRI features: in particular Pattern D (solid aggressive HCCs with CD34+/Nestin+ new-formed arteries) were isointense on T1-WI in 83% of cases and hyperintense on T2-WI in 50%. Five histologically-diagnosed HCC were diagnosed as non-malignant nodules on MRI due to their early vascularization and low aggressiveness (Pattern A). The comparison between histology and MRI confirms that a subclassification of HCC is possible in a pre-operatory setting. MRI seems to reinforce once more the identity of the different morphovascular HCC patterns and the possibility to pre-operatively identify HCCs with features of biological aggressiveness.

Subglottic cysts can cause stridor and respiratory distress in the infant. The diagnosis of subglottic cysts is often confirmed during direct laryngoscopy and bronchoscopy. We describe the case of a 6-month-old boy with bilateral subglottic cysts that were preoperatively diagnosed by magnetic resonance imaging (MRI). We also review the current literature on the diagnosis and treatment of subglottic cysts. Up until now, 63 cases of subglottic cysts were reported in the literature since 1966, and most were diagnosed by direct endoscopy. In this article, we describe a new case and we provide the first published report of the novel use of MRI in diagnosing this lesion.

Imaging evaluation of uterine masses is important to assess the type of lesion and to target surgery, if surgical excision is necessary. This can be decisive in fertile women with benign masses resembling malignancies, in order to avoid overtreatment. In this study, the magnetic resonance imaging (MRI) appearance of cotyledonoid dissecting leiomyoma of the uterus, a rare benign variant of leiomyoma mimicking malignancy, is presented.

Objective.Magnetic resonance imaging (MRI) is commonly used in autoimmune inflammatory arthritis to define disease activity and damage, but its role in gout remains unclear. The aim of our study was to identify and describe the MRI features of gout.Methods.Over a 10-year period we identified patients with gout who underwent MRI scanning of the hands or feet. Scans were reviewed for erosions, synovitis, tenosynovitis, tendinosis, bone edema, and tophi by a musculoskeletal radiologist and 2 rheumatologists in a blinded manner. MRI features in patients with uncomplicated gout were compared with features where concomitant osteomyelitis was diagnosed.Results.A total of 47 patients with gout (51 scans) were included: 33 (70%) had uncomplicated gout and 14 (30%) had gout complicated by osteomyelitis. MRI features included tophi in 36 scans (71%), erosions in 35 (69%), bone edema in 27 (53%), synovitis in 15 (29%), tenosynovitis in 8 (16%), and tendinosis in 2 (4%). Uncomplicated gout and gout plus osteomyelitis did not differ for most MRI features. However, “severe bone marrow edema” was much more common in gout plus osteomyelitis, occurring in 14/15 scans (93%) compared with 3/36 scans (8%) in uncomplicated gout (OR 154.0, 95% CI 14.7–1612, p < 0.0001). Sensitivity and specificity of “severe bone edema” for concomitant osteomyelitis were 0.93 (95% CI 0.68–0.99) and 0.92 (95% CI 0.78–0.98), respectively.Conclusion.MRI reveals that gout affects the joints, bones, and tendons. Bone edema in patients with chronic tophaceous gout is frequently mild and this contrasts with the “severe bone edema” observed in patients with concomitant osteomyelitis.

Tumefactive Multiple Sclerosis

In this report we describe a multiple sclerosis patient who developed a relapse with magnetic resonance imaging (MRI) features of tumefactive demyelination after switching therapy from natalizumab to fingolimod. Tumefactive lesions emerged 16 weeks after stopping natalizumab and eight weeks after commencing fingolimod therapy but had been absent at the time of diagnosis and throughout the preceding course of the disease. Thus, the first-time occurrence of atypical lesion features may have been caused by the change in immunotherapy. The possible relevance of natalizumab withdrawal vs fingolimod introduction is discussed against the background of recently published case studies.
