Intramuscular mesenchymal chondrosarcoma surrounded by a split fat sign mimicking a benign lesion.

Mesenchymal chondrosarcoma (MCS) is an aggressive malignant mesenchymal tumour of uncertain differentiation. This is rare, accounting for 2%-4% of chondrosarcomas. Its peak incidence is in the second and third decades, though it can occur at any age.

A case of post-HoLEP vasitis mimicking incarcerated inguinal hernia. A diagnostic approach.

Vasitis is inflammation of the vas deferens, which can be divided into acute inflammatory vasitis or chronic vasitis nodosa. Acute vasitis can present with inguinal pain, swelling, or a lump, which could mimic other common pathologies occurring at this site, particularly inguinal hernia. While ultrasound is effective in the diagnosis of epididymitis, orchitis, and hernia, this case illustrates the importance of cross-sectional imaging to establish the correct diagnosis of vasitis, to aid in the prevention of unnecessary surgical exploration and to expedite antibiotic treatment.

Juxta-articular extraskeletal myxoid chondrosarcoma mistaken for a benign cyst presenting with multiple lung metastases.

Extraskeletal myxoid chondrosarcoma (EMC) is a malignant cartilage neoplasm usually encountered in the proximal extremities. We report the case of a 58-year-old male who presented initially with a 3-month history of cough. Initial staging demonstrated a right upper lobe mass with bilateral pulmonary nodules and moderate tracer uptake in the right lung mass and right groin on positron emission tomography imaging.

A case of cerebral venous sinus thrombosis presented with SAH and isolated headache.

Cerebral venous sinus thrombosis is a rare and challenging type of stroke. Coexistence of subarachnoid hemorrhage adds complexity to the diagnostic process leading to a missed or delayed diagnosis. Isolated headaches can be the only presentation and urgent neuroimaging using CT or MR venogram plays a pivotal role in the workup of these cases.

[Effects of the anticholinesterase drug neuromidin in patients with schizophrenia with marked neurocognitive deficits].

An objective of the study was to investigate the effectiveness of neuromidin in stable schizophrenic patients with predominance of symptoms of pseudoorganic deficits. Fifty-five patients stable after a transition from routine medication to monotherapy with risperidone were randomized into two groups with add-on placebo or neuromidin treatment. Patients were studied during 24 weeks.

Extracorporeal recording of mouse hemodynamic parameters by ultrasound velocity dilution.

The use of mice as models for cardiovascular studies has traditionally been difficult because of their small size and the lack of appropriate instrumentation to perform fundamental measurements of cardiac output (CO) and total blood volume (TBV). The advent of transgenic techniques to develop mouse strains that mimic human disease makes the development of this instrumentation crucial. The current study outlines a novel technique for the determination of CO and TBV in the mouse using an extracorporeal arteriovenous (A-V) shunt, combined with the measurement of ultrasound dilution after the intravenous administration of small volumes of isotonic saline.
