Adrenal pseudotumor

The specific aim of this review is to report the features of intracranial pressure changes [spontaneous intracranial hypotension (SIH) and idiopathic intracranial hypertension (IIH)] in children and adolescents, with emphasis on the presentation, diagnosis, and treatment modalities. Headache associated with intracranial pressure changes are relatively rare and less known in children and adolescents. SIH is a specific syndrome involving reduced intracranial pressure with orthostatic headache, frequently encountered connective tissue disorders, and a good prognosis with medical management, initial epidural blood patching, and sometimes further interventions may be required...

Sclerosing pseudotumour of the orbit is a rare idiopathic chronic inflammatory process, which greatly mimics neoplasms both clinically and on imaging studies. It is therefore important to differentiate this entity from true neoplasms and to rule out any systemic associations. We present a rare case of sclerosing orbital pseudotumour in an adult man with no systemic illnesses who presented with painless progressive proptosis of both eyes and showed a gradual initial response to steroid therapy but relapsed after a 2-year interval...

Inflammatory pseudotumors are rare solid, non-neoplastic masses that can mimic pulmonary malignancy. It occurs most commonly in children and young adults and is usually found incidentally. There are many reports of the existence of this tumor in various organs in the human body. The occurrence of this tumor exclusively in the pleura has not been described before. We present a case of inflammatory pseudotumor of the pleura and its successful management.

PURPOSE: There is a paucity of reliable data and limited experience on the clinical features and therapeutic outcomes of orbital myositis. The purpose of this study was to collate data on the clinical features, imaging, diagnosis, and therapeutic effects of case reports from patients with myositis of idiopathic orbital inflammation pseudotumor in a tertiary eye hospital in China. METHODS: A retrospective study was performed on the records of 44 Chinese patients with orbital myositis...

Inflammatory pseudotumor (IPT) is a rare, locally aggressive, benign neoplasm of unknown etiology. It is uncommon in the head and neck region, particularly in the paranasal sinuses. We present an unusual case of IPT of the maxillary sinus and orbit in a 27-year-old woman who presented with cheek swelling, right orbital swelling, double vision, and associated fever and trismus. Computed tomography identified a mass with radiologic features suggestive of a malignancy of the maxillary sinus and orbit; the mass extended into the infratemporal fossa, parapharyngeal space, anterior antral wall, and surrounding soft tissue...

BACKGROUND: Headache resulting from idiopathic intracranial hypertension (IIH) in a population of moderately to obese women of childbearing age. The causes overall remain unclear. With this review, we provide an overview of clinical treatment and management strategies. RESULTS: IIH management is dependent on the signs and symptoms presented. Symptomatic treatment should attempt to lower intracranial pressure, reduce pain, and protect the optic nerves. Consideration for lumbar puncture and draining fluid as an option for reducing pressure may be helpful; however, repeated treatment is not usually favored by patients...

CASE REPORT: A patient diagnosed with necrotizing scleritis, c-ANCA+ an orbital pseudotumour, and possible multiple sclerosis in 2003 was treated with oral cyclophosphamide and steroids with partial response. Between 2005-2010 she suffered self-limited episodes. In 2010 a first scleral transplant was performed with poor outcome. She was treated with rituximab, and a second graft was performed with good results. At 12 months there was no change in magnetic resonance and the second graft healed...

Idiopathic intracranial hypertension is a common disorder affecting mainly healthy, young, overweight women. The pathogenesis of this condition is unknown, but it has been shown to follow treatment with several compounds including corticosteroids and vitamin A derivatives. This paper will offer a novel hypothesis and insight on the pathogenesis of drug induced intracranial hypertension following a review and analysis of the literature. Both corticosteroids and vitamin A derivatives have been shown to upregulate the expression of aquaporin 1, a water channel protein...

INTRODUCTION: Functional impairment of the optic nerve is characterized by visual loss, dyschromatopsia, visual field defects, relative afferent pupillary defect, and swelling or atrophy of the optic nerve. AIM: To describe the spectrum of acute optic neuropathies, focusing on clinical features, diagnosis and treatment with an emphasis on pediatric entities. DEVELOPMENT: Optic neuritis may be monophasic, recurrent, or part of a polysymptomatic demyelinating process...

BACKGROUND: Primary echinococcosis, and especially primary alveolar echinococcosis (AE) is rare among adrenal lesions. METHODS: We report a case of primary AE in a 28-year-old male with low backache and occasional upper limb pain lasting for six months, and review the pertinent but sparse literature on this disorder. RESULTS: Evaluation of the patient revealed an abdominal mass as right adrenal AE. The adrenal gland is a rare extrahepatic site of occurrence of echinococcosis, and particularly of AE...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is a syndrome consisting of headache, visual field defects and papilledema of uncertain etiology. The prospect was raised previously as to an association between aldosteronism and increased intracranial pressure in 2 middle-aged women with IIH and primary aldosteronism (PAL). Since then, 2 additional adults were identified and 2 other cases were reported from the United Kingdom, whereas 6 cases of IIH and secondary aldosteronism (SAL) in children have been reported in the English literature worldwide...

The clinical syndrome idiopathic intracranial hypertension (IIH), also termed pseudotumor cerebri, consists of symptoms of headache, nausea, vomiting and visual field defects in combination with findings of papilledema. IIH is more commonly seen in overweight women where the rise in intracranial pressure is putatively a consequence of an endocrine-based disturbance of electrolytes. Less frequently, it can also occur in men and in the pediatric age group. Associated risk factors include primary and secondary aldosteronism, pregnancy, recombinant growth hormone (r-GH) therapy, oral contraceptives, obesity, vitamin A intoxication or deficiency, Addison disease, corticosteroid therapy or acute withdrawal of steroid therapy and Cushing disease...

OBJECTIVE: To report one case of bilateral kidney pseudotumor due to sarcoidosis in a 75 year-old man with prostatic carcinoma and hypertrophic pachymeningitis. METHODS: Renal Doppler, body CT, CT-guided renal biopsy, blood analysis including angiotensin converting enzyme (ACE), blood levels and test-treatment (corticosteroid response) were performed. RESULTS: The radiological studies performed showed bilateral kidney masses and pulmonary calcified hilar adenopathies...

Extraorbital idiopathic pseudotumors of the skull base are very uncommon. We report the case of a 50-year-old woman who presented with left ophthalmoplegia and vision loss. Imaging studies revealed an enhancing lesion involving the left petrous apex and cavernous sinus. A transnasal endoscopic approach was used to obtain a biopsy of the left petrous apex. Pathology identified the lesion as an idiopathic pseudotumor. The patient was treated with high-dose steroids and steroid-sparing immunomodulators, and she experienced a significant improvement...

The authors report three rare cases of neuroschistosomiasis lacking extracranial involvement. No parasitic eggs were detected in the stool with the Kato-Katz thick smear methods. Computed tomography of the brains showed hypodense signals, and magnetic resonance imaging showed isointense signals on T1-weighted images, hyperintense signals on T2-weighted images, and intensely enhancing nodules in the brain after intravenous administration of gadolinium. High-grade gliomas were suspected, and operations or radiosurgery was performed...

PURPOSE: To characterize clinical features, diagnostics studies, treatments, and outcomes of patients with histologically proven idiopathic sclerosing orbital inflammation (ISOI), to define optimal management for this recalcitrant disease, and to determine changes in characterization and management by comparing our results with the last significant literature review. METHODS: A search of the U.S. National Library of Medicine: National Institutes of Health's electronic database for cases and case series in the English literature of biopsy-proven ISOI published between March 1994 and September 2010 was conducted...

Inflammatory pseudotumors are a relatively uncommon pathology of uncertain etiology, generally considered to be reactive in origin. They may be observed in different locations as single or multiple masses. One of the possible forms of presentation is intrapulmonary. Despite its low frequency, this pathology should be considered in the differential diagnosis of lung nodules, even though the histologic results and the imaging tests can become confusing. In addition, pulmonary inflammatory pseudotumors present a low malignancy with good response to surgical treatment as well as to pharmacological therapy, although to a lesser degree...

BACKGROUND: The diagnosis of retroperitoneal lesions is one of the most difficult areas in surgical pathology. The retroperitoneal space allows both primary and metastatic tumors to grow silently before the appearance of clinical signs and symptoms. Fine needle aspiration cytology has shown promising role in establishing the diagnosis in this region. OBJECTIVES: This study was undertaken to evaluate the reliability of ultrasonography (USG)-guided fine needle aspiration cytology (FNAC) in distinguishing between benign and malignant lesions in the retroperitoneum, and to correlate the diagnosis by cytology of retroperitoneal masses with the results obtained by histology...

Benign intracranial hypertension (Pseudotumor cerebri) has been described as related to the reduction in steroid levels in Cushing's disease (CD), especially after surgical remission. Ketoconazole is a common and effective adjuvant therapy for hypercortisolism, but the major concern is liver enzyme dysfunction. We describe here the case of a 12-year old girl with CD who developed benign intracranial hypertension during treatment with ketoconazole. She presented headache, vomiting, a black spot on her right temporal visual field, and signs of elevated intracranial pressure...
