“…Only 2 previous cases of intraventricular IP have been reported in pediatric patients and in both instances presented in males with radiographic evidence of biventricular hydrocephalus [4,5]. Importantly, on examination in the current case, IP involving the choroid plexus in a 16-year-old female was not associated with focal neurological deficits or signs of hydrocephalus.…”

“…There are several reported cases of intracranial IP, 13 of which are intraventricular lesions [4,5,6,7,8,9,10,11,12,13,14] (table 1).

Inflammatory pseudotumor (IP) is a benign process that most commonly occurs in the lung and orbit. Extension into the central nervous system is extremely rare, and primary intraventricular lesions of the lateral ventricles are even more infrequent with only 2 cases reported in pediatric patients to date. Here, the authors present an unusual case of IP occurring in a 16-year-old female presenting with a 2-week history of progressive headaches and vomiting, without focal neurological deficits or radiographic evidence of hydrocephalus. The patient underwent left parietal craniotomy and complete resection of the tumor, with no signs of recurrence at 3-month follow-up. Although the rarity of intraventricular IP in pediatric patients can make its initial identification difficult, IP should be considered as a potential diagnosis in this population wherein good outcomes may be achieved following surgical resection.

Inflammatory pseudotumor is an uncommon lesion with unknown etiology characterized by sclerosing inflammation which clinically and radiographically mimics a neoplastic lesion. A 47-year-old man presented with sudden headache and dysarthria. Brain CT scan revealed a 2.6× 2.2 cm sized, round, and hyperdense mass in the anterolateral wall of the left lateral ventricular trigone. On MR imaging studies, the mass showed low signal intensity in the wall of the trigone on T2-weighted image, central mixed (iso-and high-) signal intensity with peripheral lowsignal intensity on T1-weighted image. Subtle staining of left choroid plexus with irregular shaped distal branch of anterior choroidal artery was found on the cerebral angiography. These findings suggested a small tumorous lesion originated from the left choroid plexus. During the hospital days, the mass manifested as repeated hemorrhages. The mass was successfully removed via left occipital transcortical approach. The histopathological report of the specimen was hemorrhage and fibrosis, with dense lymphoplasma cell infiltration, suggestive of an inflammatory

“…Only 9 cases of IP in the ventricles have been reported in detail (Table 1), 1,4,5,8,10,11,13,14) occurring in 2 females and 7 males aged 15-73 years (mean 49 years), indicating a tendency to occur in middle-aged or older men. 10) Eight of 9 cases developed in the lateral ventricle, with the remaining case developing in the fourth ventricle.…”

A 15-year-old boy was referred to our hospital with a rare case of inflammatory pseudotumor (IP) in the lateral ventricle manifesting as complaints of headache and low-grade fever. Computed tomography and magnetic resonance imaging demonstrated a well-demarcated and enhanced tumorous lesion in the right lateral ventricle. Intraoperative findings showed a hard mass with feeding arteries from the choroid plexus around the foramen of Monro in the right lateral ventricle, although the mass was not attached to the wall of the lateral ventricle. The lesion was totally resected, and the histopathological diagnosis was IP. The present and previous cases suggest that good outcomes are obtained by surgical removal and treatment of hydrocephalus. IP should be considered in the differential diagnosis of hard tumorous lesions with good enhancement and no tumorous staining in the ventricle.
