intraorbitale Raumforderungen

Orbitales,

retrobulbäres Teratom bei einem 2 Monate alten Kind, somit kongenital: Oben T2 axial, T1 axial, T2 koronar; unten T1 KM 3 Ebenen

Non-Hodgkin-Lymphom

Manifestation in der Tränendrüse links. Obere Reihe: Axial T2, T1, T1 FatSat KM. Untere Reihe: Koronar T1, T1 FatSat (Dixon), T1 FatSat KM.

Toddler with

a left medial canthus mass. Coronal T1 MRI without contrast (left) shows a round low signal intensity left medial canthus lesion that is high signal intensity on T2 (middle) and that does not enhance with contrast (right).The diagnosis was lymphatic malformation of the orbit.

Toddler with

left orbital swelling. Coronal CT with contrast of the orbits in bone (above left) and soft tissue (above right) windows show bony destruction in the superolateral aspect of the orbit caused by a soft tissue mass. Coronal T1 MRI without (below left) and with contrast (below right) of the orbits better show the soft tissue mass superolateral to the left orbit which enhances avidly.The diagnosis was Langerhans cell histiocytosis of the orbit.

MRI pattern

of retinoblastoma with optic nerve involvement (sagittal enhanced T1-weighted sequence)

Neurofibromatosis

type 2: proptosis as the initial presentation. Lateral rectus muscle is not distinct. Meningioma (e) possibly extends through superior orbital fissure. It is isointense on T2WI.

Neurofibromatosis

type 2: proptosis as the initial presentation. Left sphenoid wing meningioma encasing left internal carotid artery (thick arrow) and middle cerebral artery (thin arrow) with intraorbital extension (e).

Paediatric

orbital alveolar soft part sarcoma recurrence during long-term follow-up: a report of 3 cases and a review of the literature. a Nonaxial proptosis of the left eye in patient 3, with downward displacement of the globe; b and c, T2-weighted axial and coronal series showing a well-defined recurrent mass with intermediate signal intensity in the posterosuperior orbit
