Pseudotumour of the maxillary antrum

Abstract

Orbital pseudotumour is a non-specific inflammation of the orbit which forms a tumour-like mass composed of increased connective tissue and ground substance with vascular proliferation and an infiltrate of chronic inflammatory cells. No demonstrable aetiological agents are found locally, and there is no evidence of specific disease entities such as Hodgkins, SLE or temporal arteritis.The condition may present in many different ways to the otolaryngologist, and is therefore a rare but important differential diagnosis to be born in mind. We report a rare case of orbital pseudotumour presenting initially with involvement of the maxillary antrum and in association with Riedel's thyroiditis.

Transcatheter arterial embolisation for paediatric inflammatory pseudotumour of the maxillary sinus

“…Sclerosing lesions with a large fibrotic component exhibit more aggressive features, and show little response to highdose corticosteroids or radiotherapy. 9,14,[17][18][19] • The pathogenesis and characteristics of inflammatory pseudotumour are controversial • Surgical excision, high-dose corticosteroids and radiation therapy have been used to treat this condition • A case of inflammatory pseudotumour in the maxillary antrum is presented, in which arterial embolisation was successful, suggesting an additional therapeutic option for this condition Ahuja et al reported successful combination therapy of a proximal haemophilic pseudotumour arising in a child with mild haemophilia, using arterial embolisation prior to surgery. However, no previous report has presented the utility of arterial embolisation as the sole treatment for inflammatory pseudotumour.…”

Plasma cell granuloma of the maxillary sinus: A case report and literature review

“…15 However, some have postulated that there is a morphologic spectrum among plasma cell granulomas that may predict their response to treatment and prognosis. 1,16,23 One generally accepted histopathologic classification system was established by Fujii et al 23,24 : (1) 18 Some have suggested that optimal treatment might vary depending on tumor morphology. It has been proposed that lymphoid-predominant lesions would respond best to radiotherapy, whereas granulomatous lesions might respond better to high-dose corticosteroids.…”

“…1,16,18,23 Twenty-eight cases of plasma cell granuloma affecting the paranasal sinuses, nasal cavity, and pterygopalatine fossa have been reported (Table 1). No particular age group predominates, unlike similar lesions in the orbit or lungs that tend to affect children, young adults, and middle-aged individuals.…”

“…1,9,14,16 -18,21,26,27 Several authors have reported cranial nerve palsies. 14,16,18,23,28 Keen et al 22 documented perineurofibrosis, loss of function of the mandibular nerve, and axonal demyelination. De Vuysere et al 14 documented three cases of perineural involvement affecting the mandibular nerve, the maxillary nerve, and the inferior alveolar nerve.…”

Inflammatory Pseudotumor and Related Lesions of the Oral and Maxillofacial Region: A critical reappraisal based on recent information.

“…Locations of published IPT are shown in Table 2. Reported cases of IPT associated with periapical lesions in the jawbones, orbital IPT involving the sinus and PCG were not listed (22,23). We also excluded several ambiguous cases without histologic verification (24,25).…”
