OBJECTIVE A Sylvian fissure arachnoid cyst (SAC) is a well-recognized location for an intracranial arachnoid cyst in the pediatric population. For those cysts, which can rupture and be accompanied by a subdural hygroma or hematoma, several treatment modalities have been reported. We report clinical and radiological outcome of fenestration of these cysts by(More)
A 70-year-old woman with a 6-year history of seropositive rheumatoid arthritis (RA) and asymptomatic interstitial lung disease (ILD) began taking etanercept for ongoing arthritis despite treatment with methotrexate (MTX) and bucillamine. MTX was discontinued before introduction of etanercept. She developed lung injury 8 weeks after starting etanercept.(More)
OBJECTIVE To elucidate the cut off levels of serum KL-6 indicating patients with interstitial pneumonitis (IP) and patients with active IP associated with connective tissue diseases (CTDs). METHODS CTD patients whose serum KL-6 level was measured were included. IP was diagnosed on the basis of medical records including XP/CT findings, and active IP was(More)
A 38-year-old woman with pancytopenia and liver dysfunction was diagnosed with active systemic lupus erythematosus (SLE). On days 9 and 10 of admission, peripheral blood smears showed macrophages phagocytosing platelets, and reactive hemophagocytic syndrome (HPS) was diagnosed. Hemophagocytic syndrome was successfully treated with high-dose prednisolone(More)
Sarcoidosis is a systemic granulomatous disease with systemic vascular involvement, that is, granulomatous angiitis and microangiopathy. To determine if there is vascular involvement in cutaneous sarcoidosis, we examined 42 skin specimens taken from 32 patients with cutaneous lesions of sarcoidosis. Cutaneous sarcoidosis was prevalent in older females with(More)
Seventy-nine specimens of lung parenchyma from 61 patients with sarcoidosis were examined ultrastructurally with a focus on alveolitis, and they were compared with specimens of hypersensitivity pneumonitis (HP) and the percentage of lymphocytes in bronchoalveolar lavage fluid (BALF). Lymphocytes and monocytes were frequently observed in the capillary(More)
A 27-year-old man who had a history of bronchial asthma, eosinophilic enteritis, and eosinophilic pneumonia presented with fever, skin eruptions, cervical lymphadenopathy, hepatosplenomegaly, atypical lymphocytosis, and eosinophilia two weeks after receiving trimethoprim (TMP)-sulfamethoxazole (SMX) treatment. After the withdrawal of TMP-SMX and the(More)
A case of "sclerosing hemangioma" (pneumocytoma) of the lung with lymph node metastasis is reported. A 22-year-old Japanese man was found to have a well-defined round lesion in the right lung (S7), which increased in size slightly during a 2-year follow-up period. He underwent right lower lobectomy with a preoperative diagnosis of a benign lung tumor. The(More)
To evaluate the occurrence of granulomatous angiitis and microangiopathy in the lung with sarcoidosis, transbronchial lung biopsy specimens were examined from 174 cases with sarcoidosis. Granulomatous angiitis was seen in 72 cases, which corresponded to 53% of the cases with granulomata. Granulomatous angiitis showed venous involvement (65%), both venous(More)
