Visual and auditory hallucinations revealing cerebellar extraventricular neurocytoma: uncommon presentation for uncommon tumor in uncommon location.

OBJECTIVE: Visual and auditory hallucinations in relation to a cerebellar tumor are rarely reported in children. Primary origin of extraventricular neurocytoma (EVN) in the cerebellum is very rare. CLINICAL PRESENTATION: We report on a case of a cerebellar EVN in a 13-year-old girl with the initial symptoms of psychiatric manifestations for more than 2 months. Magnetic resonance imaging of the brain revealed a patchy enhanced tumor in the paramedian left cerebellar region. No obstructive hydrocephalus was noted. INTERVENTION: Total surgical removal of the tumor was performed. The tumor was initially diagnosed as an oligodendroglioma. After special immunohistochemical studies, the final definitive diagnosis was an EVN without isocitrate dehydrogenase mutation. CONCLUSION: EVNs located in the cerebellum are extremely rare. We discuss the clinical symptoms and histological-immunohistochemical features of this rare tumor in that rare location.

Magnetic resonance imaging findings in primary lymphoma of the liver: a case report.

INTRODUCTION: Primary lymphoma of the liver is an extremely rare finding, with the few such cases reported in the literature to date describing indeterminate imaging findings, being focused more on computed tomography. To the best of our knowledge, there is no prior report describing magnetic resonance imaging scan findings with such a lesion. In the case reported here, magnetic resonance imaging gave us the opportunity to ascertain the correct diagnosis, confirmed by histopathology, thus avoiding unnecessary surgery or other treatments. Although this condition is rare, knowledge of magnetic resonance imaging findings will be invaluable for radiologists and other medical subspecialties that may face such cases in the future in helping to provide adequate management for affected patients. CASE PRESENTATION: A focal lesion was incidentally detected by ultrasound in a 75-year-old asymptomatic Albanian man being treated for benign hypertrophy of prostate. Chest and abdomen computed tomography scans did not reveal any abnormal findings besides a solid focal lesion on the right lobe of the liver and a mild homogenous enlargement of the prostate gland. Subsequently, magnetic resonance imaging of the upper abdomen was performed for better characterization of this lesion. Our patient was free of symptoms and his laboratory test results were normal. CONCLUSIONS: The magnetic resonance imaging scan results showed some distinctive features that helped us to make the correct diagnosis, and were thus very important in helping us provide the correct treatment for our patient.

Spondylodiscitis due to Sallmonela in an immunocompetent patient.

Salmonella is a gram-negative bacillus that penetrates in human from contaminated food or water. Sallmonela spondylodiscitis is a rare condition occur secondary to hematogenous spread after bacteremia episode. We presented a successful treatment with Levofloxacin in a 26 years old immunocompetent male with a septic form of sallmonelosis complicated with lumbar spondylodiscitis without surgery. He was treated with intravenous Levofloxacin for three weeks and was discharged from the hospital with oral Levofloxacin for more than two months. Clinical and laboratory evaluation two months after oral treatment resulted normal.
