Asymptomatic 30-year-old female with a known orbital vascular lesion and a right tentorial lesion. MRI Brain:Redemonstrated is a small 3 mm extra-axial, T1 bright lesion along the right tentorial leaf with susceptibility effect which may suppress on fat suppressed images. This lesion is unchanged compared to previous exams. In the vicinity of this lesion there is an increased number of prominent venous structures when compared to the contralateral side. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. Small left maxillary sinus mucous retention cyst or polyp. The paranasal sinuses and mastoid air cells are otherwise unremarkable. The skull, and scalp soft tissues are grossly unremarkable.MRI Orbits:Redemonstrated is a lobular right intraconal space mass located between the right lateral rectus muscle and optic nerve with mild lobulation measuring 1.3 x 1.4 cm compared to 1.5 x 1.7 cm previously. On early postcontrast images, the lesion demonstrates heterogeneous and complete enhancement. On delayed postcontrast imaging, the lesion enhances nearly uniformly. No new lesions are identified. The globes are intact. The extraocular muscles are intact. The lacrimal glands are symmetric and within normal limits in size and configuration. There is no optic nerve enhancement appreciated. The suprasellar cistern is intact.MRI Face/ Neck:There is no evidence of measurable mass lesions or significant lymphadenopathy based on size criteria. The thyroid and major salivary glands are unremarkable. The major cervical vessels are patent. The osseous structures are unremarkable. The airways are patent. The imaged portions of the lungs are clear.
1.Slight overall decrease in size of the enhancing right intraconal space mass compared to the prior exam. The imaging features, and particularly the pattern of early and late enhancement, favor the diagnosis of cavernous hemangioma.2.Stable small 3 mm extra-axial, T1 bright lesion along the right tentorial leaf demonstrating susceptibility and possible fat suppression. The increased number of prominent venous structures in the vicinity of this lesion is of uncertain significance.
