Orbital metastasis is a rare occurrence found only in about 3 - 10% of all prostate cancers. A 72 years male presented with proptosis of the left eye associated with pain, blurred vision and frequent headaches for the past 8 months. Past medical history had symptoms of bladder outflow obstruction for 3 years. MRI brain and orbit with contrast was consistent with a large soft tissue mass in the ...

Gangliogliomas (GG) are mixed glioneuronal tumors of the central nervous system (CNS), occurring mostly in the pediatric population, with common sites being temporal lobes and less commonly in the frontal and parietal lobes. We report a case of a 7-year-old child who presented with bilateral visual defects for 6 months. Magnetic resonance imaging (MRI) of the brain revealed an intensely enhanci...

A solitary brain tumour originating from a lung adenocarcioma in a 68-year-old man is reported. The imaging features were discordant with the clinical picture and prompted surgery and subsequent histological examination. Results of computed tomography and magnetic resonance imaging suggested that the lesion was a haematoma. However, during positron-emission tomography using 2-fluoro-2-deoxy-D-g...

Tuberculosis has been an important public health problem in both developing and develop nations. Tuberculosis of the central nervous system is rare. Tuberculosis meningitis and tuberculoma are the two most important manifestations of tuberculosis of the CNS. Intracranial tuberculomas may be solitary or multiple. Solitary tuberculomas may be indistinguishable from cranial abscess or primary brai...

a 50-year-old male underwent a check-up for an insurance company. chest x-ray revealed a large ball-like lesion in the posterior mediastinum. the finding was confirmed by computed tomography (ct) scan (figure 1). the patient was referred to our center, where he had a successful mass removal surgery (figure 2). pathology identified the mass as neurinoma.

Mixing of active neutrinos with sterile ones generate “induced” contributions to the mass matrix of active neutrinos ∼ mS sin θaS , where mS is the Majorana mass of the sterile neutrino and θaS is the active-sterile mixing angle. We study possible effects of the induced matrix which can modify substantially the implications of neutrino oscillation results. We have identified the regions of mS a...

Introduction: Papillary thyroid carcinoma (PTC) constitutes 75–85% of all thyroid cancers. PTC usually presents as a subtle, commonly slow-growing, painless thyroid mass or a solitary nodule in the neck. This presentation of a cystic neck lump, without the presence of a thyroid nodule, may imitate the course of a benign disease, thus delaying diagnosis and proper treatment.  Case Report: Thr...

purpose:  to report a patient with pretarsal dermoid cyst. patient and findings: a 2.5-year-old girl presented with a pretarsal upper lid mass and underwent excisional biopsy. a 1.0´1.0 cm cystic mass attached to upper lid tarsus was completely excised. pathologic study of the specimen revealed a dermoid cyst. conclusion: although pretarsal dermoid cyst is rare; it should be considered in all c...

The term `spatial hemineglect' refers collectively to disorders of spatial cognition, which concern specific sectors of space with reference to a given coordinate system. Patients with cerebral lesions involving the posterior-inferior parietal and the premotor cortex, most often in the right hemisphere, sometimes fail to explore the extra-personal and personal sectors of space contralateral to ...

Isolated hepatic tuberculoma is localized hepatic tuberculosis (TB) without bile duct involvement, which presents as solitary or multiple nodular mass lesion of liver mimicking a neoplastic lesion in radiological evaluation. Clinical presentation and biochemical tests for liver functions show non-specific abnormality, which is not helpful for diagnosis. As the treatment, modality of isolated he...
