Polycystic subdural hygroma associated with immunoglobulin G4-related intracranial hypertrophic pachymeningitis: a case report

Abstract

Background: Recent studies have examined hypertrophic pachymeningitis as an IgG4-RD. However, there are no reports of immunoglobulin G4 (IgG4)-related hypertrophic pachymeningitis with polycystic subdural hygroma. Case presentation: A 56-year-old man presented to the hospital with complaints of a persistent, pulsatile, occipital headache and general malaise. Magnetic resonance imaging of the brain revealed hypertrophic pachymeningitis with polycystic subdural hygroma and hematoma. Based on the dural biopsy findings and exclusion of other diseases, the patient was diagnosed with immunoglobulin G4 (IgG4)-related hypertrophic pachymeningitis. IgG4related diseases may cause subdural hygroma more commonly than other diseases that cause hypertrophic pachymeningitis. Conclusions: This is the first case report discussing polycystic subdural hygroma and hematoma with IgG4-related hypertrophic pachymeningitis.

The great imposter: A case report of IgG4‐RD hypertrophic pachymeningitis with skull lytic lesion and pulmonary nodules

“…Intracranial hypertrophic pachymeningitis rarely accompanies subdural hygroma or hematoma. Only three cases have been reported in the literature, of which two cases involved a diagnosis of IgG4‐RDs 14–16 . Our case presented as an SDH mimic, which is also rarely reported with HP 1,17 .…”

“…Only three cases have been reported in the literature, of which two cases involved a diagnosis of IgG4-RDs. [14][15][16] Our case presented as an SDH mimic, which is also rarely reported with HP. 1,17 Skull involvement with IGG4-RD HP has been reported in a few cases.…”

IgG4-related hypertrophic pachymeningitis with tumor-like intracranial and intracerebral lesions

“…IgG4-related hypertrophic pachymeningitis accounted for 8.8% out of 159 cases in a study on hypertrophic pachymeningitis in Japan [ 35 ]. It manifests as localized or diffused thickening of the dura mater [ 23 , 27 ]. Clinical manifestations depend on the location of the inflammatory lesion and on compression of neural structures leading to functional deficits [ 3 , 5 ].…”

“…A dural biopsy is commonly needed to establish a definite diagnosis [ 2 , 30 ]. Immunomedulatory treatment is considered the treatment of choice and was suggested to avoid disease recurrence [ 7 , 24 , 27 ].…”
