Idiopathic orbital inflammatory pseudotumor is a chronic neoplasm-like inflammatory reaction, usually affecting the orbital tissues of both eyes and orbit. Isolated optic nerve involvement by the idiopathic inflammatory process is a rare finding and very few reports are available. Here a case of an isolated orbital nerve inflammatory pseudotumor presenting with gradually progressive unilateral ...

We describe 2 patients with inexorably progressive pseudotumor syndrome (intracranial hypertension without mass lesion or ventriculomegaly) both initially misdiagnosed as having idiopathic intracranial hypertension and who were eventually found to have spinal leptomeningeal lymphoma. Neither had, at any time, any clinical signs of a spinal cord or root lesion. We discuss the possible implicatio...

Among 38 children with pseudotumor cerebri only 3 cases were due to ear disease or its complications. The commonest cause was a refeeding syndrome either due to nutritional deprivation or as an early finding in the treatment of cystic fibrosis. It is uncommon to find the cause of pseudotumor in older children but in those under 6 years the cause was found in 85%. Because of the adverse effects ...

Inflammatory pseudotumor refers to a nonmalignant or low-grade neoplastic lesion characterized by the presence of spindle-cell proliferation with abundant inflammatory cells. Lung and orbit are the most frequent sites of occurrence, but the lesions may originate in nearly every site in the body, including the abdomen. We present a rare and interesting case of inflammatory pseudotumor of the col...

Calcifying fibrous pseudotumor is a rare, benign, hypocellular tumor-like lesion that is characterized by the presence of dense hyalinized collagenous tissue interspersed with small spindle cells, dystrophic calcifications, or psammomatous and variable lymphoplasmacytic infiltrations. We report the case of a 37-year-old woman with a posterior mediastinal mass, in close contact with the distal t...

Orbital pseudotumor, is a heterogeneous group of disorders characterised by orbital inflammation and is a rare clinical entity and a diagnosis of exclusion. We report two cases with typical clinical manifestation and magnetic resonance images, but unresponsive to corticosteroid treatment which turned out to be caused by herpes simplex virus type I. Viral etiology must be carefully evaluated, es...

The objective of this study is to report and discuss a rare and inflammatory cause of exophthalmos. This report describes a patient with exophthalmos, who was initially diagnosed with euthyroid Graves' with good response to therapy. After 8 years of follow-up, she had recurrence of symptoms and a new evaluation revealed the final diagnosis of orbital pseudotumor. Orbital pseudotumor is an uncom...

We present an unusual case of a primary lumbar disk-space mass that presumably developed secondary to a chronic hyperextension spinal fracture associated with spinal stenosis. This injury resulted in the appearance of a lumbar intervertebral disk-space mass or pseudotumor. The pseudotumor most likely resulted from a prior spinal fracture, leading to a fused hyperextension deformity in a patient...

We present serial cardiovascular magnetic resonance (CMR) in a case of cardiac pseudotumor (inflammatory myofibroblastic tumor). The diagnosis proved difficult and was helped by myocardial tissue characterization using CMR. Intrinsic contrast and extrinsic contrast (using gadolinium-DTPA perfusion, early and late imaging) differentiated between normal and pathological tissues and demonstrated t...

Pseudotumor cerebri or idiopathic intracranial hypertension is a neurological syndrome characterized by signs and symptoms of intracranial hypertension without clinical or radiological evidence of infective or space occupying lesions. Iatrogenic factors are frequent; in particular, cases of pseudotumor cerebri associated with all-trans-retinoic acid treatment in acute promyelocytic leukemia (AP...
