Case Reports
Megaesophagus and Megaduodenum Found Incidentally on a Routine Chest Radiograph During a Health Examination.
Chronic idiopathic intestinal pseudo-obstruction (CIIP) caused by impaired intestinal peristalsis leads to intestinal obstructive symptoms. A 20-year-old man had marked esophageal dilatation that was found incidentally on chest radiography during a health examination. Chest/abdominal contrast-enhanced computed tomography and endoscopy showed marked esophageal and duodenal dilatation without mechanical obstruction. ⋯ CIIP was suspected in the patient's father, suggesting familial CIIP. The patient likely had signs of pre-onset CIIP. This is the first case of suspected CIIP in which detailed gastrointestinal tract examinations were performed before symptoms appeared.

Glomerulopathy with fibronectin deposits (GFND) is a rare hereditary kidney disease with autosomal dominant inheritance. A 21-year-old woman who had been diagnosed with GFND 10 years ago was admitted for investigation of a rapid decline in her renal function, hemolytic anemia, and cardiac dysfunction. ⋯ Comprehensive treatments against hypertension and anemia improved the renal function. Although there have been few reports of vascular lesions in GFND, we suspect that endothelial hyperpermeability resulting from hypertension caused the fibronectin deposition and narrowing of the extraglomerular vascular lumens, thereby accelerating hypertension and inducing hemolytic anemia.

An 80-year-old man was transferred to our institution with lower limb edema and worsening dyspnea following the administration of diuretic medication. Transthoracic echocardiography and computed tomography revealed a giant hepatic cyst (176×190 mm) compressing his right atrium and inferior vena cava (IVC). ⋯ The procedure was uneventful, and he was discharged without any complications on postoperative day 9; he had no recurrent symptoms or hepatic cysts at the postoperative 2-month follow-up. Therefore, a giant hepatic cyst can cause IVC syndrome, and laparoscopic deroofing is a beneficial approach for the treatment of accessible cysts.

Case Reports
Pneumatosis Intestinalis in Lung Cancer Induced Twice by Different Drugs: Bevacizumab and Pemetrexed.
A 72-year-old man diagnosed with stage 4 lung adenocarcinoma developed asymptomatic pneumatosis intestinalis while undergoing treatment with first-line chemotherapy, which included carboplatin, paclitaxel, and bevacizumab (BEV). He was treated conservatively. ⋯ To our knowledge, this is the first case in which pneumatosis intestinalis was induced twice by two drugs in a patient with lung cancer. BEV and PEM are often administered to patients with lung cancer; thus, it should be noted that pneumatosis intestinalis may occur as an adverse event in patients treated with these drugs.

We herein report a 75-year-old man who developed disturbed consciousness with polynuclear cell dominant pleocytosis and low glucose and extremely high interleukin (IL)-6 levels in his cerebrospinal fluid. The biopsy specimen from his right supraclavicular lymph node showed the infiltration of inflammatory cells positive for IgG, IgG4 and IL-6. ⋯ However, he developed myelodysplastic syndrome (MDS) and died 18 months later. The extremely high IL-6 may have been related to the rare neurological manifestations and development of MDS in the present case.
