[A case of Wegener's granulomatosis with pachymeningitis].

A 49-year-old man was admitted to our hospital because of headache, rhinorrhea, and general fatigue. Chest CT revealed some lung nodules bilaterally, and laboratory data were positive for C-ANCA. Brain MRI revealed the findings of pachymeningitis. Wegener's granulomatosis (WG) was diagnosed by the pathological findings of his paranasal sinuses and kidneys. Most of his symptoms remarkably improved with oral corticosteroids and cyclophosphamide. A MEDLINE search about WG with pachymeningitis obtained only 15 cases previously reported in Japan. Considering those reports about WG with pachymeningitis in both Japan and overseas, in some cases pachymeningitis preceded WG, and relatively more cases than normal WG were negative for C-ANCA, furthermore the pathological findings of pachymeningitis were mainly necrotizing granuloma. Therefore pachymeningitis with WG might be mainly composed of granuloma rather than angitis and which might be a expansion of granulomatous inflammation of upper respiratory tract.

[A case of pulmonary amebiasis].

A 57-year-old man was admitted to our hospital because of dyspnea and right abdominal pain. Chest X-ray radiogram showed right massive pleural effusion. Ultrasonic echogram of abdomen showed a unilocular liver cyst. He was treated with intravenous infusion of meropenem, and percutaneous pleural and liver drainage were performed. At the time of drainage, we injected contrast medium into the liver cyst and confirmed a fistula connecting to the right pleural space. Initially we made a diagnosis of bacterial empyema and liver abscess, yet there was no response to the initial treatment. Cultures of pleural effusion and liver abscess were confirmed to be negative. A few days after admission, the patient stated that he was a homosexual. Liver amebiasis and its perforation became the most likely diagnosis, and metronidazole was administered. On admission day 21, tests for anti-amebic antibody were positive. Finally he fully recovered. We must be aware of the rare pulmonary manifestation of amebiasis. We report this case and review the literature.
