Petrous apex effusions can present with aural fullness, hearing loss and dizziness. Although they can be followed-up when asymptomatic, clinical management of symptomatic patients is controversial. In this study, we present clinical and radiological findings of a 24-year-old patient with bilateral petrous apex effusion. She had been complaining of bilateral aural fullness and dizziness for 2 years. Radiological examinations revealed bilateral petrous apex effusion. After medical treatment, her symptoms gradually disappeared. In all previous published studies, unilateral petrous apex effusions were reported. To our best knowledge, this is the first patient with trapped fluid in bilateral petrous apex.

La thrombophlébite du sinus caverneux (TPSC) est une affection rare surtout dans son origine otologique, l'incidence et la gravité de cette dernière ont beaucoup décrû depuis l'avènement des antibiotiques. Cette pathologie a une symptomatologie initiale sournoise et peu évocatrice, en effet elle associe à des degrés divers une altération de l'état général, des signes ophtalmologiques liés à la gêne au retour veineux et des troubles de l'oculomotricité. La TDM avait mis en évidence une thrombophlébite du sinus caverneux associée à un abcès cérébral et à un abcès rétro-pharyngé avec une oto-mastoïdite homolatérale. Le malade a été traité par une antibiothérapie à large spectre associée à une héparinothérapie, avec mastoïdectomie droite et drainage de l'abcès rétro-pharyngé. L'évolution a été marquée par la régression totale de la paralysie faciale, avec reperméabilisation du sinus caverneux et disparition totale de l'abcès temporal au contrôle scannographique. Le patient a gardé comme seule séquelle une cécité mono oculaire gauche. Conclusion : La thrombophlébite du sinus caverneux est une affection rare, surtout dans son origine otogène elle doit être diagnostiquée et traitée le plutôt possible, afin de prévenir les séquelles ou d'obtenir la régression de ces dernières. Le traitement doit associer une antibiothérapie à large spectre, les anticoagulants et un drainage chirurgical approprié du foyer septique. Mots-clés : Thrombophlébite du sinus caverneux, Otite moyenne aiguë, complication.

“…Acquisitions in axial or coronal planes by using Ͻ1-mm-thick sections may be obtained and then reformatted in other planes. [2][3][4][5][6][7] The CS is composed of 2 layers of dura that split to form a septate venous channel. Each dural wall contains an outer layer apposed to bone and an inner layer in contact with blood or CSF.…”

“…These findings are essential for deciding therapeutic modalities such as microsurgery, radiation therapy, or medical treatment as well as for appropriate planning of surgery or radiation therapy. [1][2][3][4][5][6][7][8] Because the MR imaging features of many of these lesions overlap and are often nonspecific, we will emphasize those features that allow one to formulate a reasonable differential diagnosis.…”

SUMMARY:Our aim was to review the imaging findings of relatively common lesions involving the cavernous sinus (CS), such as neoplastic, inflammatory, and vascular ones. The most common are neurogenic tumors and cavernoma. Tumors of the nasopharynx, skull base, and sphenoid sinus may extend to the CS as can perineural and hematogenous metastases. Inflammatory, infective, and granulomatous lesions show linear or nodular enhancement of the meninges of the CS but often have nonspecific MR imaging features. In many of these cases, involvement elsewhere suggests the diagnosis. MR imaging is sensitive for detecting vascular lesions such as carotid cavernous fistulas, aneurysms, and thromboses.
