BACKGROUND: Hepatic inflammatory pseudotumor (HIP) related to IgG4 is a poorly understood entity. It is a rare finding that can simulate malignant liver tumors. Pathogenesis has been associated with pathological inflammatory response. Corticosteroids are considered standard of care once a firm diagnosis has been established. CASE REPORT: We report a case of a 60-year-old man with chronic pancreatitis who was admitted to our hospital with suspicious liver tumor. Imaging studies were inconclusive...

Intracranial hypertension is a rare entity in prepubertal children, and its differential diagnosis includes a number of systemic diseases, drugs, vitamin deficiencies and excesses, and hereditary conditions. Infectious aetiology is rare. The case of a 9-year-old boy with intracranial hypertension secondary to acute neuroborreliosis is described. He presented with daily pulsatile frontotemporal headache, pallor, photophobia and phonophobia. His neurological examination revealed papilledema with no nuchal rigidity...

Pulmonary inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor, and is considered an inflammatory pseudotumor. Here, we report of a 37-year-old woman with severe cough and stridor who was diagnosed with primary IMT of the lungs, with adenocarcinoma in situ based on the pathology in December 2012. A year later, transabdominal ultrasonography demonstrated a solid mass in the uterine wall that was initially diagnosed as a leiomyoma. However, postoperative histological examination and immunohistochemical staining revealed it as a uterine metastasis of the lung IMT...

The group of inflammatory pseudotumors (IPTs) encompasses a variety of rare neoplastic and nonneoplastic entities described to occur in almost every location in the body and whose clinical features and aggressive imaging findings (varying from infiltrative to mass-forming lesions), frequently mimic those of malignant tumors. The radiologic features of IPTs are variable and nonspecific, the imaging findings depending on the body location and involved organ. Abdominopelvic IPTs are rare and the purposes of this review, therefore, are to familiarize the radiologist with the wide spectrum of computed tomography and magnetic resonance imaging findings of IPTs in various locations throughout the abdomen and pelvis, discussing the imaging features that allow consideration of IPTs in the differential diagnosis of soft-tissue masses within the pertinent clinical setting...

There is a broad range of inflammatory, pseudotumoral, and benign lesions that may masquerade as pancreatic malignancies, often representing a challenge to the radiologist. Unawareness of these entities can lead to inadequate differential diagnoses or misdiagnosis, with important prognostic and therapeutic consequences. The purpose of this article is to revisit a spectrum of lesions, varying from common to exceedingly rare nonmalignant, that may mimic malignant pancreatic neoplasms on imaging, identifying relevant features that may contribute to reaching the correct diagnosis...

OBJECTIVES: Multiple sclerosis (MS) is the most common chronic disabling disease of the central nervous system (CNS) in young adults. It is characterized by the presence of multiple demyelinating inflammatory lesions disseminated in the CNS. Pseudotumoral lesions (PL) are rarely observed in patients with MS. METHODS: These atypical lesions can pose a diagnostic problem, especially when they are present at disease onset. RESULTS: Most MS patients with PLs only have a single episode throughout their disease course, which reflects its low tendency of recurrence...

The inflammatory myofibroblastic tumor (IMT) is a rare lesion of unclear etiology and variable clinical course, consisting of a proliferation of fibroblasts and myofibroblasts, mixed with inflammatory cells. Synonyms of IMT are inflammatory pseudotumor and plasma cell granuloma reflecting the alleged inflammatory nature attributed to this lesion, even though this heterogeneity in the disease denomination is probably involved in a dispersion of the literature data. Among primary pulmonary neoplasms, it represents the most frequent endobronchial tumor of childhood and beyond the lung it has been described mainly in the bladder, mediastinum and mesentery...

Spindle cell lesions of the breast cover a wide spectrum of diseases ranging from reactive tumor-like lesions to high-grade malignant tumors. The recognition of the benign spindle cell tumor-like lesions (nodular fasciitis; reactive spindle cell nodule after biopsy, inflammatory pseudotumor/inflammatory myofibroblastic tumor; fascicular variant of pseudoangiomatous stromal hyperplasia) and tumors (myofibroblastoma, benign fibroblastic spindle cell tumor, leiomyoma, schwannoma, spindle cell lipoma, solitary fibrous tumor, myxoma) is crucial to avoid confusion with morphologically similar but more aggressive bland-appearing spindle cell tumors, such as desmoid-type fibromatosis, low-grade (fibromatosis-like) spindle cell carcinoma, low-grade fibrosarcoma/myofibroblastic sarcoma and dermatofibrosarcoma protuberans...

This report describes the case of an 85-year-old man who underwent left hemicolectomy for descending colon cancer and hepatic segmentectomy for metastatic liver cancer. Seven years after the liver surgery, an abdominal CT scan revealed a tumor in the remnant liver. He also presented with colon diverticula in the ascending colon, which was located close to the liver tumor. With a preoperative diagnosis of metastatic liver cancer, the tumor was resected with S8 segmentectomy. Histopathological examination of the resected tumor revealed a hepatic inflammatory pseudotumor, not metastatic liver cancer...

A 60-year-old man was admitted for a liver mass(S3), which rapidly increased in size during intraductal papillary mucinous neoplasm(IPMN)follow-up. Although EOB-MRIwas performed, the mass could not be accurately diagnosed as hepatic cancer. Thus, we performed a lateral segmentectomy. In the resected specimen, a solid tumor mass was clearly bound in segment 3 of the liver. Since histopathology revealed no malignant cells and many IgG4-positive cells, we confirmed the diagnosis as IgG4-related inflammatory pseudotumor of the liver...

Granulomatosis with polyangiitis is rare in children. We report a case of a 12-year-old male who presented with new symptoms of left eyelid swelling and ptosis. Magnetic resonance imaging showed an enhancing orbital mass suspicious for a neoplasm. Excisional biopsy was performed. Microscopic examination revealed fibrovascular tissue with dense collagenous fibrosis and mixed inflammatory infiltrate that included many plasma cells. Many small and medium-sized blood vessels showed granulomatous and necrotizing vasculitis with disruption of the vessel walls and fibrinoid necrosis...

Rationale (hypothesis): IgG4-related disease (IgG4-RD) is a pathological entity recently recognized by the medical world that can affect any organ or system. However, there is insufficient data about this disease in medical literature. Aim (objective): A more extensive clarification of the IgG4 molecule, the diversified aspects of IgG4-related disease, and the response of this disease to treatment, will provide a crucial understanding of the immune system and other diseases now known to be associated with IgG4...
