Abstract This systematic review aims to clarify and comprehensively detail the sometimes variable published imaging features as well as the pathogenesis, clinical diagnostic criteria, and treatment options of IgG4-Related Diseases (IgG4-RD) in the head and neck to aid the radiologist in diagnosing relapse and new sites of disease. A literature search in PubMed and EMBASE for reported cases of IgG4-RD was performed in December 2019. Case reports or series of IgG4-RD in the head and neck in adults that included sufficient imaging and pathology findings were included. This yielded 50 reports. IgG4-RD locations included the orbits, thyroid, pituitary gland, paranasal sinuses, salivary and parotid glands, larynx, pharynx, cervical lymph nodes, meninges, and skull base. Most lesions demonstrated non-specific homogenous CT attenuation, diffuse enhancement, isointense/low T2 signal intensity, and low T1 signal intensity. 6 cases from our institution followed previously reported imaging patterns.

Abstract IgG4-related disease (IgG4-RD) is an emerging clinical disease entity characterized by tumefactive lesions at multiple sites with a dense lymphoplasmacytic infiltrate rich in IgG4+ plasma cells. Although almost any organ can be affected, IgG4-RD is most likely to involve the submandibular, lacrimal, or parotid glands in the head and neck region. However, skull base involvement presenting as otogenic skull base osteomyelitis (SBO) is rare. We encountered a 70-year-old male with IgG4-RD p...

ABSTRACT IgG4 related disease was recognized as a unified disease entity only 15 years ago. Awareness of IgG4 related disease has increased worldwide since then, and specialists are now familiar with most of its clinical manifestations. Involvement of the pancreato-biliary tract, retroperitoneum/aorta, head and neck, and salivary glands are the most frequently observed disease phenotypes, differing in epidemiological features, serological findings, and prognostic outcomes. In view of this multif...
Abstract Introduction IgG4 related disease is a fibroinflammatory condition characterised by lymphoplasmocytic infiltration with predominance of IgG4+ plasma cells, fibrosis, and in most cases elevated IgG4 serum levels. It can affect any organ and result in varying clinical manifestations. Steroids are the cornerstone of treatment, however there is a high percentage of relapse. Recent studies have demonstrated favourable effects with rituximab. Objective To evaluate effectiveness related to the...
Background IgG4-related disease (IgG4-RD) is an immune-mediated, systemic, fibroinflammatory disease. IgG4-RD may manifest in almost every part of the human body. Here, we describe 3 patients with a skull base manifestation of IgG4-RD that mimicked malignancy. Case Description Patient 1, a 73-year-old male, presented with a mass in the left nasopharynx and clivus. Patient 2, a 73-year-old male, presented with a mass in the left petrous bone and clivus with involvement of the left jaw joint. Pati...
OBJECTIVE: IgG4-related disease (IgG4-RD) can cause fibroinflammatory lesions in nearly any organ. Correlation among clinical, serologic, radiologic, and pathologic data is required for diagnosis. This work was undertaken to develop and validate an international set of classification criteria for IgG4-RD. METHODS: An international multispecialty group of 86 physicians was assembled by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR). Investigators use...

Background. IgG4-related hypophysitis (IgG4-RH) is a rare disease, and its prevalence remains unclear. In recent years, an increasing number of cases have been reported because of the increasing recognition of this disease. We aimed to summarize case reports of IgG4-RH and outline the clinical features and outcomes. Methods. We performed PubMed search of articles using the search terms “hypophysitis [AND] IgG4.“ Consequently, only 54 English articles (76 cases) met Leporati’s diagnostic criteria...

Background Back pain is a leading reason for patients to seek medical attention. Although musculoskeletal causes are common, patients can also present with rarer etiologies. Case Description A 50-year-old man presented with 2 months of isolated upper back pain initially suspected to be secondary to overuse muscular strain. During the next 3 months, his pain worsened, and he developed lower extremity dysesthesia and subjective weakness, despite normal neurological examination findings. Nonreveali...
