Inflammatory pseudotumor (IP) is a rare type of benign tumor. Although initially identified in the lung, it has now been identified in a number of somatic and visceral sites, but mesenteric presentation is uncommon and has a variable clinical presentation. As inflammatory pseudotumor mimic malignancy both clinically and radiologically, the radiologist should be familiar with this entity. The only effective treatment is complete surgical resection. We present the case of a 55-year-old woman who presented with chronic abdominal pain and was diagnosed with a mesenteric inflammatory pseudotumor, in an attempt to illustrate the different imaging aspects of this benign condition in ultrasound, computed tomography and magnetic resonance imaging, and to simplify the description of these tumors.

A subcutaneous mass in the anterior region of the thorax, (presternal region).Subcutaneous metastases in ovarian cancer are rare, occurring in 0.9% to 5.8% of cases. They are usually a late manifestation that arises several years after the initial diagnosis and often serve as a poor prognostic indicator. Their presence suggests a reported median survival ranging from 3 to 18 months.subcutaneous metastases can be categorized into umbilical metastases, commonly referred to as Sister Joseph's nodules (SJN) the most prevalent type, and non-SJN cutaneous metastases.We present the unusual case of a 57-year-old woman who underwent surgical intervention and received adjuvant chemotherapy for serous ovarian adenocarcinoma. She presented for consultation 5 years later with a painful presternal mass, and the histopathological examination of the mass revealed a metastasis of the primary ovarian tumor.

Persistent fetal vasculature, previously called persistent hyperplastic primary vitreous, is a rare congenital condition where a component of fetal vessels within the eye fails to regress, leading to visual acuity decrease or loss. We present a case of a 13-year-old male patient, with a history of second-degree consanguinity, psychomotor development retardation, intellectual deficit from birth, in addition to a progressive bilateral visual acuity decrease. He recently presented a leukocoria in the right eye. Ultrasound and MRI were performed showing a linear structure traversing the vitreous antero-posteriorly, in addition to a retinal detachment and lens luxation, suggestive of posterior persistent fetal vasculature. We draw attention to the late age at diagnosis due to the insidious evolution in our case, and we highlight the importance of ultrasound and MRI in establishing the diagnosis and identifying associated brain malformations.

En plaque meningioma is a rare type of meningioma characterized by an infiltrative nature, sheet-like growth, and at times invading the bone. We report here a case of en plaque meningioma. The patient was a 66-year-old woman presenting with headache and painful bilateral proptosis. Cerebral magnetic resonance imaging revealed a bilateral en plaque meningioma showed as a bilateral hyperostotic of greater wing sphenoid bone associated with bilateral thickening and enhancement of the dura in the anterior temporal area and the retroclival region invading bilaterally the cavernous sinus, the prechiasmatic portion of the optic nerve, and the lateral rectus muscle of the orbit through the superior orbital fissure causing bilateral exophthalmia. Due to invasion of the cavernous sinus and the orbital apex, a subtotal but extensive removal combined with bony decompression of the cranial nerves at the superior orbital fissure and optic canal followed by adjuvant radiotherapy frequently produces good functional and cosmetic results, and over a 3-year period, follow-up magnetic resonance imaging scans showed no obvious signs of recurrence.
