tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...

INTRODUCTION Tumefactive fibroinflammatory lesion is an idiopathic fibrosclerosing disorder occurring in the head and neck region. It is one of a broad spectrum of entities named inflammatory pseudotumors and, as the name suggests, it mimics a lot of diseases such as malignancies or infections. Combined with its rarity, tumefactive fibroinflammatory lesion can be a tremendous diagnostic challen...

A tumefactive lesion of central nervous system (CNS) is defined as a mass-like lesion with a size greater than 2 cm in brain detected by magnetic resonance imaging (MRI). Neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore, can prevent an unnecessary brain biopsy. Here we emphasized on determining the nature of a CNS tumefactive lesions with the help of MRI and...

Objective: A 65-year-old man presented with a nine-month history of swelling in the midline of the forehead. After surgical intervention, this lesion was found to be a tumefactive fibroinflammatory lesion of the frontal sinus. This case report and review aims to report this new location for tumefactive fibroinflammatory lesion, and to discuss whether, in retrospect, there would have been altern...

BACKGROUND Multiple sclerosis (MS) is less common in Asia, including Taiwan, and some characteristics of MS in Asians differ from those of Caucasians. Tumefactive brain lesion is even rarer in MS patients. OBJECTIVE To review patients with tumefactive MS and compare them with those in other studies investigating tumefactive demyelinating lesions and our Taiwanese typical MS patients. METHOD...

A previously healthy 31-year-old woman presented with a 2-week history of progressive left hemiparesis. MRI (figure) demonstrated a 3 cm enhancing mass in the right posterior frontal white matter with several smaller lesions in the white matter of the contralateral hemisphere and brainstem (figure, D). A stereotactic biopsy of the large lesion was performed to establish the diagnosis. This show...

Tumefactive demyelinating lesion is defined as large solitary demyelinating lesion with imaging characteristics mimicking neoplasm. These atypical features include size more than 2 cm, mass effect, edema, and/or ring enhancement. Distinguishing tumefactive lesions from other etiologies of intracranial space occupying lesions is essential to avoid inadvertent surgical or toxic chemotherapeutic i...

ABSTRACT Tumefactive fibroinflammatory lesions are rare idiopathic benign fibrosclerosant that clinically and radiologically simulate malignancy. These have a high recurrence rate, so patients should be monitored for the long term. We present case of 87 years old patient who came to emergency room with 1-month history an expansive maxilary lesion. A biopsy was performed result tumefactive
