Infl ammatory pseudotumor is a well known but poorly understood pathologic entity. It is associated with an unusual growth of fi brotic tissue admixed with varying amounts of infl ammation that displaces and compresses normal anatomic structures, resulting in dysfunction. Pseudotumors have been found in multiple locations-the orbit in particular-but to the best of our knowledge, none has previously been reported as an isolated sinus lesion. We describe a case of primary sclerosing fi broinfl ammatory pseudotumor of the maxillary sinus that manifested as recurrent unilateral maxillary sinusitis in a 47-yearold woman. Th e patient was managed with surgery and oral steroids with full resolution of her symptoms. We also review the presentation, diagnosis, and treatment of fi broinfl ammatory pseudotumors within the context of the current literature.

Hemangiomas are the most common tumor of the liver and distinguishing them from malignancy is important. This is a report of 3 hemangiomas in 2 patients that exhibit transient washout of gadoxetate disodium (Eovist), relative to blood pool and liver parenchyma, a characteristic that is used to diagnose hepatocellular carcinoma in at-risk patients. It is important to recognize that high-flow hemangiomas can exhibit transient washout when using a small volume of injected contrast agent. This finding is unlikely to be present on CT examinations because of the larger volume of contrast administered.

A woman in her 70s with a history of radiation therapy for a nasal cavity lymphoma 15 years prior presented with complaints of chronic right nasal obstruction and right epiphora. She denied epistaxis or pain. She described having undergone 2 surgical procedures in the interim for occluded nasolacrimal duct, at 1 year and 8 years after treatment.On nasal endoscopy, a smooth, pink, friable mass was seen abutting the posterior aspect of the right inferior turbinate and extending to fill most of the nasopharynx. This mass was visible through the left choana as well. There was also an erythematous irregular area, smaller than 1 cm, on the right lateral nasal wall, corresponding to the orifice of the nasolacrimal duct. The middle turbinates were intact, and no other lesions were seen. The oropharynx and oral cavity were clear, and findings from fiber-optic laryngoscopy was normal. Orbital examination revealed right epiphora without additional abnormality.Maxillofacial computed tomographic (CT) imaging along with a magnetic resonance imaging (MRI) of the head were performed. Coronal CT image with bone window (Figure, A), sagittal T1-weighted image without contrast (Figure, B), coronal T2-weighted (Figure, C), and contrast-enhanced, fat-saturated, T1-weighted ( Figure, D) images are presented for interpretation. The patient was brought to the operating room for biopsy.
