“…Inflammatory pseudotumor is a title devised by Umiker and Iverson in 1954 due to overlapping symptomatic and radiological findings with pancreatic malignancy [15]. It is a benign, unusual entity which tends to involve all locations in the body but most frequently present in orbit and the lung.…”

“…Umiker et al [5] coined the term inflammatory pseudotumor on account of its resemblance to malignant etiology, both clinically and radiologically. The presence of acute and chronic inflammatory infiltrate with varying degrees of fibrous response characterizes IPT [6]. Fibromyxoid pseudotumor, pseudosarcomatous myofibroblastic tumor, pseudosarcomatous fibromyxoidtumor, nodular fasciitis, and inflammatory myofibroblastic tumor are other names of this entity [7].…”

Unusual cause of urinary retention in a child: inflammatory pseudotumor of the urinary bladder

et al. 2021

Background Urinary bladder masses are uncommon in the pediatric age group and pose a diagnostic challenge, often necessitating histopathological differentiation and confirmation. An unusual mimic of neoplastic bladder mass is inflammatory pseudotumor, and timely identification and diagnosis of which prevents undue patient stress and radical treatment. Case presentation We present a case of a 7-year-old female child who presented with hematuria, and a urinary bladder mass was detected on ultrasound which was further characterized by magnetic resonance imaging (MRI) and diagnosed as an inflammatory pseudotumor (IPT) on histopathology. Conclusions This case report describes the imaging features of IPT along with a list of differential diagnoses emphasizing the need for radiologists to be aware of this surprising and rare entity.

“…The term "inflammatory pseudotumor" (IPT) was coined by Umiker and Iverson in 1954, [1] and represents a rare, benign, mass-forming lesion that has been reported in virtually every organ. The clinical, radiological and histological findings can closely mimic spindle cell neoplasms, including malignant tumors.…”

Inflammatory pseudotumor (IPT) is a rare benign mass forming lesion that has been reported in virtually every organ, and can closely mimic spindle cell neoplasms. Mycobacterial spindle cell pseudotumor (MSP) represents a small proportion of IPT of the lymph node, which occur in immunocompromised patients, posing a diagnostic challenge. We report three cases of MSP involving two AIDS patients who presented with generalized lymphadenopathy, and one immunosuppressed patient with a mediastinal mass. Biopsy in these cases revealed effaced architecture replaced by proliferating fibrohistiocytic spindle cells, fibrosis and polymorphic inflammatory infiltrate. Inflammatory pseudotumors and other spindle cell neoplasms of the lymph node can show overlapping morphologic features, resulting in diagnostic confusion. A differential diagnosis of Mycobacterial spindle cell pseudotumor should be kept in mind when approaching localized or generalized lymphadenopathy in an immunocompromised patient.
