Pseudotumor inflamatorio nasosinusal: reporte de un caso / Inflammatory pseudotumor sinonasal: a case report / Pseu-dotumor inflamatório nasossinusal: relatório de um caso

El pseudotumor inflamatorio (PTI) es una entidad no neoplásica, de etiología desconocida, caracterizada por la proliferación de un infiltrado inflamatorio policlonal sobre un estroma de tejido conjuntivo. Pueden ser definidos como lesiones que clínica y radiológicamente simulan neoplasias. El pseudotumor inflamatorio puede causar dolor facial, obstrucción nasal, exoftalmos y discapacidad visual y con frecuencia causa la erosión y destrucción ósea. Los corticoesteroides, la radioterapia y la cirugía se han utilizado como modalidades de tratamiento, solos o en combinación.

The inflammatory pseudotumour (IPT) is a nonneoplastic entity of unknown origin, and is characterised by a proliferation of connective tissue and a polyclonal inflammatory infiltrate. May be defined as lesions that clinically and radiologically simulate neoplasms. Inflammatory pseudotumour sometimes causes facial pain, nasal obstruction, exophthalmos and visual impairment, and often causes bone erosion and destruction. Corticosteroids, radiotherapy and surgery have been used as treatment modalities either on their own or in combination.

O pseudo-tumor inflamatório (PTI) é uma entidade não neoplásica de etiologia desconhecida, caracterizada pela proliferação de um infiltrado inflamatório policlonal em um estroma do tecido conjuntivo. Podem ser definidos como lesões que simulam neoplasias clínica e radiologicamente. O pseudo-tumor Inflamatório pode causar dor facial, obstrução nasal, exoftalmia (olhos saltados), deficiência visual e freqüentemente provoca o desgaste e a destruição óssea. Os cortiçoesteroides, a radioterapia e a cirurgia têm sido usadas como modalidades de tratamento, por si só ou em combinação.

Idiopathic Orbital Inflammatory Pseudotumour Mimicking Optic Nerve Sheath Meningioma- A Case Report

A 42-year-old Malay gentleman presented with progressive painless blurring of vision on his left eye associated with ocular ache, redness and increasing proptosis. Examination revealed presence of relative afferent papillary defect with visual acuity of counting finger, and 6/6 on the right eye. Extraocular muscle movement of the left eye was restricted to ten percent in all directions. Computed tomography (CT) and magnetic resonance imaging (MRI) showed enhancing mass occupying the left orbital apex. Diagnosis of optic nerve sheath meningioma was made, and patient subsequently went for radiotherapy. His symptoms subsided completely, until he presented with similar visual complains, and fullness of the upper lid two years later. A repeated MRI showed enlargement of superior and lateral recti muscles with extension to lacrimal gland region. Biopsy of the lacrimal gland revealed inflammatory cells consistent of inflammatory pseudotumor. High dose systemic steroid was instituted, followed by slow tapering of oral steroid. His symptoms completely resolved, and latest visual acuity was 6/9, with no recurrence, to date.

Seudotumor inflamatorio pulmonar: presentación de 2 casos y revisión de la literatura / Pulmonary inflammatory pseudotumour: two case report and review of theliterature

Primary lung tumours in children are rare, the most common lesions seen in clinical practice are metastatic disease. The majority of children who present with a primary or secondary pulmonary malignancy will present coincidentally while seeking attention for another medical problem, or with non-specific abnormalities such as cough with collapse or consolidation on the chest x-ray. Primary malignant tumours of the lung are the most common, this group is made up of carcinoid tumours, bronchogenic carcinoma and pleuropulmonary blastoma. Benign primary pulmonary tumours are inflammatory pseudotumour or plasma cell granuloma and hamartoma. Often, the possibility of a primary or secundary pulmonary tumour is considered only when radiographic abnormalities or symptoms persist or fail to respond to therapy, many children are asymptomatic until they have advanced disease, which delays diagnosis even further. The aim of this article is show our experience of two patients with inflammatory pseudotumour and literature review.

Los tumores pulmonares primarios en niños son muy poco frecuentes, siendo más reportadas las lesiones metátasicas. La mayoría de los pacientes que presentan un tumor pulmonar ya sea primario o secundario, son hallazgos de algún examen generalmente imagenológico, como parte del estudio de otras causas o en presencia de síntomas inespecíficos como tos asociada a atelectasia o condensación. Los tumores pulmonares primarios malignos son los más frecuentes, comprenden el tumor carcinoide, carcinoma broncogénico y blastoma pleuropulmonar. Los tumores pulmonares primarios benignos son el seudotumor inflamatorio (sTi) o granuloma de células plasmáticas y el hamartoma. Se debe tener un alto índice de sospecha en el diagnóstico de tumor pulmonar primario o secundario, frente a la persistencia de síntomas o si presenta una lesión en la radiografía de tórax que no se modifica o invade localmente a otros tejidos adyacentes a pesar del tratamiento. El objetivo de este artículo es mostrar nuestra experiencia de 2 pacientes portadores de sTi y hacer una revisión de la literatura.

Clinical, imaging and pathological features of intracerebral inflammatory pseudotumour (report of 1 case) / 临床神经病学杂志

Objective To investigate the clinical,imaging (CT and MRI) and pathological features of intracerebral inflammatory pseudotumour. Methods The clinical, neuroimaging and neuropathological data of a patient with intracerebral inflammatory pseudotumour were analyzed retrospectively. Results The manifestations of this patient included headache, nausea, vomiting, fever and seizures. Brain MRI showed abnormal high T1 and T2 signals in the right frontal lobe and midline shift. The resection pathology showed brain tissue swelling, loss of normal neuron outline, massive inflammatory infiltrations in perivascular spaces. Although the patient was treated with operation, dehydration and antibiotics, he died eventually.Conclusions Intracerebral inflammatory pseudotumour is an unusual disease in clinical practice. This disease is diagnosed mainly depended upon pathological examinations because of no specific clinical and imaging manifestations. The prognosis is not good although operative treatment is performed.
