Rosette-forming glioneuronal tumour (RGNT) is a rare central nervous system (CNS) neoplasm that typically arises in the fourth ventricle. It is even more uncommon to arise outside the midline. In this paper, we report 2 cases of RGNT: one located in the fourth ventricle (a typical site), and the other in the right cerebellar hemisphere (a rare site). Both cases were misdiagnosed on imaging, and the results were inconsistent with the pathological diagnosis. The aim of the article is to deepen medical practitioners’ understanding of RGNT by learning from these 2 cases, summarizing cases located in the cerebellar hemispheres and systematically reviewing RGNT.

✓ Except for villous hypertrophy of the choroid plexus that may not be true tumors, multiple choroid plexus papillomas are extremely rare. The authors report a case involving multiple choroid plexus papillomas that were distinct from villous hypertrophy. These lesions were localized, one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. A review of the literature revealed that this case represented the first reported case of true multiple choroid plexus papillomas documented by findings on magnetic resonance imaging.

Merkel cell carcinoma (MCC) is a very aggressive primary cutaneous neoplasm most often occurring on the head and neck of the elderly. Spontaneous regression of MCC was first described in 1986. A 79-year-old woman with MCC on the right cheek underwent spontaneous regression of the malignancy, documented by photographic follow-up, computed tomography, and histologic studies. A review of the literature is presented. Complete clinical and histologic regression of MCC was observed in the present case. Although the literature documents 11 similar cases, only 6 can be regarded as complete spontaneous regressions following exclusive performance of a biopsy (primary complete spontaneous regression). Primary complete spontaneous regression of MCC is infrequent, and most case reports describe this phenomenon in women with MCC on the cheek. The reasons underlying regression are unknown.

✓ Two cases of paraventricular cavernous angiomas are presented. In one, the cavernous angioma was found in the right wall of the fourth ventricle, and in the other in the right thalamus encroaching upon the third ventricle. Both patients had onset of symptoms suggesting a tumor. Good results were obtained by the microsurgical approach to these malformations. The computerized tomography findings typical of cavernous angiomas are reviewed.

Abstract Background: Yolk sac tumor also known as endodermal sinus tumor, is a rare intracranial germ cell tumor. We reported a case of yolk sac tumor in cerebellar hemisphere, and reviewed associated literatures. The majority of tumor locations are near the midline. On review of literature, very few case reports of intracranial yolk sac tumor have been published, and there is only one case report has described a yolk sac tumor arising from the cerebellum. Case presentation: A two years old boy admitted to our hospital due to headache and unsteady gait for six days. CT and MRI demonstrated a tumor in the right cerebellar hemisphere, and the blood and cerebrospinal fluid alpha-fetoprotein were found increased. It was diagnosed as yolk sac tumor after operation comfirmed by histopathological examination. Postoperative chemotherapy was performed, and the patient suffered no tumor recurrence one year and a half after the surgery. Conclusions: The clinical characteristics and imaging diagnosis of intracranial yolk sac tumor are lack of specificity, the comfirmed diagnosis is depending on the combination of elevated alpha-fetoprotein and histopathological examination.

ABSTRACT Two artificial cerebrospinal fluid mixtures, one having a higher than normal sodium, but lower than normal potassium content, the other having a lower than normal sodium, but higher than normal potassium content, were perfused alternately through the cerebral ventricular system of seven dogs, from the right lateral ventricle and down through the third ventricle, aqueduct and fourth ventricle. During this procedure blood was collected through the adrenal vein and the concentration of cortisol (11β, 17,12-trihydroxy-pregn-4-eme-3,20-dione), cortisone (17,21-dihydroxypregn-4-ene-3,11.20-trione), corticosterone (11β,21-dihydroxy-pregn-4-ene3,20-dione). compound S (11-dihydroxy-3,20-dioxo-pregn-4-en-18-al) and aldosterone (11β.21-dihydroxy-3,20-dioxo-pregn-4-en-18-al) determined. A gradual and marked increase in the secretion of all the cortical compounds was observed during the procedure. This pattern was not altered by changing from one of the artificial cerebrospinal fluid mixtures to the other.

BackgroundIntraperitoneal (IP) administration of antibiotics is a mainstay of therapy in the treatment of peritoneal dialysis–related peritonitis. The therapeutic options against gram-positive organisms in patients intolerant to vancomycin are limited.MethodsThis case report and review of the literature used a search of PubMed with the terms “daptomycin,” “intraperitoneal,” and “peritoneal” for 2004 through 7 February 2013 to find relevant publications.ResultsIn addition to our patient, we identified 6 case reports of IP daptomycin for the treatment of peritonitis. Our patient was treated with a 14-day course of IP daptomycin, with resolution of signs and symptoms of peritonitis. She presented again 7 weeks later with signs and symptoms of peritonitis and was treated with a repeat course of IP daptomycin. Among the 6 patients reported in the literature, 4 received loading doses of daptomycin. Daptomycin 20 mg per liter of dialysate was administered in 4 patients, and the other 2 patients received higher doses based on body weight (milligrams per kilogram). Treatment duration averaged 10 or 14 days. In all 6 cases, clinical cure was reported.ConclusionsAlthough limited to case reports, the available literature suggests that IP daptomycin is a viable alternative for peritoneal dialysis–related peritonitis. However, routine use of this agent must be cautioned, because further prospective studies are required.

AbstractMusculo-skeletal complaints in a patient suffering from systemic lupus, with co-existing chronic renal failure, undergoing immunosuppressive treatment after kidney transplantation, can have a varied etiology. The aim of this work was to present a case based review of differential diagnosis of knee pain in such a patient. A literature search was carried out using MEDLINE/PubMed, Google Scholar and EBSCO, with no time limit. We undertook a systematic review of the literature published in English, limited to full-text publications of original articles, letters to the editor, and case reports in peer-reviewed journals, for a discussion and analysis of studies reporting arthralgia in patients with lupus after kidney transplantation. We present a case report of a 45-year-old woman with lupus nephritis, after kidney transplantation, who started to complain of increasing pain in the knees, most pronounced at night and after physical activity approximately 2 years after transplantation. Extensive causal diagnostics were carried out, which revealed bilateral extensive regions of bone infarction in the femur and tibia, chondropathy, degenerative changes of medial meniscuses in the body and posterior horn as well as chondromalacia of the patella. Establishing the right diagnosis is crucial for implementing appropriate treatment.

The literature on palinopsia (visual perseveration) is reviewed, utilizing case reports of 46 patients who demonstrated this symptom. The most common etiologies for this symptom are space-occupying lesions, cerebral infarct, and seizure activity. The vast majority are due to central nervous system pathology occurring in the posterior (occipital or parieto-occipital) region, often in the right hemisphere. Proposed mechanisms for palinopsia are also discussed.

Introduction: lipoma of corpus callosum is a very rare benign congenital tumor, which can be isolated or associated with varying degrees of dysgenesis of the corpus callosum. It may be asymptomatic or manifested by non-specific signs such as seizures, headache, neurological deficit or dementia. Magnetic resonance imaging makes the diagnosis easily. Case report: We report two cases of two young people, one 19 years old and the other 21 years old who presented a different neurological symptomatology a seizure and headache, magnetic resonance imaging revealed a lipoma of the corpus callosum in the two patients. Conclusion: Lipomas of the corpus callosum are rare asymptomatic lesions, mainly associated with dysgenesis of the corpus callosum. Diagnosis occurs accidentally during diagnostic procedures for brain disorder. Magnetic resonance imaging is the most useful modality for differential diagnosis.
