We herein report a 73-year-old man with isolated hypertrophic pachymeningitis (HP) showing serological and pathological characteristics of both IgG4-related disorders and granulomatosis with polyangiitis. The patient presented with chronic onset headaches and ophthalmalgia. Brain magnetic resonance imaging (MRI) revealed a hypertrophic enhanced dura mater. ⋯ A dura mater biopsy showed infiltration of numerous IgG4-positive plasma cells and granulomatous inflammation without apparent vasculitic lesions, storiform fibrosis, or obstructive phlebitis. Corticosteroid treatments improved his clinical symptoms and MRI findings. There have been reports of MPO-ANCA-positive IgG4-related HP presenting as granulomatous inflammation in the dura mater.

Hepatic hemangiomas are benign liver tumors, and most of them progress asymptomatically. We report a case of hepatic hemangioma considered the cause of fever. A 53-year-old woman had a fever of 40°C for about 3 months without infection. ⋯ She was afebrile after the operation. The pathological diagnosis was hematoma inside cavernous hemangioma. It should be noted that a bleeding hepatic hemangioma may cause fever of unknown origin and be indicated for resection.

An 82-year-old Japanese man with idiopathic pulmonary fibrosis (IPF) experienced dyspnea after using a waterproofing spray in a closed room. He presented with hypoxemia and his chest computed tomography showed additive bilateral diffuse ground-glass attenuation on fibrosis, which was diagnostic of an acute exacerbation of IPF (AE-IPF). ⋯ Autopsy findings showed diffuse alveolar damage with honeycombing. His medical history and autopsy histopathology suggested AE-IPF caused by the inhalation of a waterproofing spray.

Case Reports
Constrictive Pericarditis with Cardiac Ascites Caused Spontaneous Bacterial Peritonitis.
Patients with constrictive pericarditis (CP) typically present with symptoms related to right-sided heart failure, such as cardiac ascites. Spontaneous bacterial peritonitis (SBP) usually arises in association with ascites secondary to hepatic cirrhosis. ⋯ In this case, pericardiectomy improved both the hemodynamics and the ascites, while therapy with diuretics alone was insufficient. It is important to consider SBP in the differential diagnosis when any abdominal symptoms or an inflammatory response is found in patients with heart failure and cardiac ascites.
