“…Hemostatic materials commonly used for hemostasis may cause a granulomatous reaction that may produce space-occupying mass lesions termed textiloma (or gossypiboma) that are clinically or radiologically apparent. Intracranial body granuloma reactions initially provoke no clinical symptoms, but they may appear months or even years after surgical procedure [1][2][3][4]. All classes of hemostatic agents may cause a granulomatous reaction that may mimic recurrent or progressive intracranial tumor, radiation necrosis, abscess, resolving infarction, or intracranial rebleeding on postoperative imaging studies, depending on the particular clinical history of each patient.…”

During craniotomy, hemostatic materials such as oxidized cellulose and cotton pads, commonly used to control bleeding, may cause a granulomatous reaction that may produce spaceoccupying mass lesions termed textiloma (or gossypiboma). We present a 46-year-old female who underwent a right frontotemporal craniotomy and surgical removal of intraparenchymal cerebral hemorrhage, and who developed a textiloma during the postoperative period causing seizures. Granulomatous reactions due to hemostatic agents have been reported experimentally, as well as after cranial and spinal operations. We emphasize that although it is rare, an adverse reaction such as a postoperative textiloma due to hemostatic material and subsequent granuloma formation can result in a false image of rebleeding, tumor recurrence, radiation necrosis, or postoperative abscess, depending on the particular clinical history of each patient.

“…Sarcoid granulomas are often initially misdiagnosed as glioma (1–4), or in other locations as meningioma (5, 6) or trigeminal schwannoma (7). Other inflammatory syndromes with MRI characteristics suggestive of glioma include fungal granuloma (8), eosinophilic granuloma (9), foreign body reactions to surgical (10), or embolization material (11), or inflammatory pseudotumor (12). These reports all state that the granuloma “mimicked” or “masqueraded” as a glioma on MRI (1–4, 8–11).…”

Glioma Mimics: Magnetic Resonance Imaging Characteristics of Granulomas in Dogs

et al. 2019

Granulomas can “mimic” gliomas on magnetic resonance imaging (MRI) in human patients. The goal of this retrospective study was to report canine brain granulomas that were consistent with glioma based upon MRI, report their histologic diagnosis, and identify MRI criteria that might be useful to distinguish granuloma from glioma. Ten granulomas, initially suspected to be glioma based on MRI, were ultimately diagnosed as granulomatous meningoencephalomyelitis ( n = 5), infectious granulomas ( n = 3) or other meningoencephalitis ( n = 2). Age was 1.6–15.0 years and two dogs were brachycephalic breeds. MRI characteristics overlapping with glioma included intra-axial, heterogeneous, T2-weighted hyperintense, T1-weighted hypointense to isointense mass lesions with contrast-enhancement. Signals on fluid attenuation inversion recovery, gradient echo and diffusion weighted imaging also matched glioma. Peri-lesional edema and mass effect were toward the high end of findings reported for glioma. MRI characteristics that would be considered unusual for glioma included dural contact ( n = 4), T2-hypointensity ( n = 2), concomitant meningeal-enhancement ( n = 9), and minor changes in the contralateral brain ( n = 2). Cerebrospinal fluid analysis revealed albuminocytological dissociation or mild pleocytosis. These cases show that granulomas can “mimic” glioma on canine brain MRI. In individual cases, certain MRI findings may help increase the index of suspicion for granuloma. Lack of pronounced cerebrospinal fluid pleocytosis does not exclude granuloma. Signalment is very useful in the suspicion of glioma, and many of these dogs with granuloma were of ages and breeds in which glioma is less commonly seen.

“…Such granulomas are usually caused by hemostatic agents that are deliberately left behind during craniotomies (1, 2). Other causative synthetic materials include silicone-coated sheets used as dura mater substitutes, chemotherapy wafers, and agents employed for embolization of highly vascular tumors or arteriovenous malformations such as polyvinyl alcohol or N-butyl-2-cyanoacrylate (1, 3). …”

MR Spectroscopy and Perfusion MR Imaging Findings of Intracranial Foreign Body Granuloma: a Case Report

We report a case of intracranial foreign body granuloma that showed features of a high grade tumor on magnetic resonance (MR) imaging. However, the relative cerebral blood volume was not increased in the enhancing mass on perfusion MRI and the choline/creatine ratio only slightly increased on MR spectroscopy. The results suggest that the lesion is benign in nature. Perfusion MRI and MR spectroscopy may be helpful to differentiate a foreign body granuloma from a neoplastic condition.
