Abstract Background A small percentage of patients with foreign body ingestion develop complications, which have a variety of clinical presentations. Less than 1% of cases require surgical intervention. We present a patient with an abdominal wall abscess resulting from a fish bone that pierced the cecum. The patient was treated laparoscopically. Case presentation A 55-year-old Japanese man presented to our hospital with a complaint of right lower abdominal pain. A physical examination revealed tenderness, swelling, and redness at the right iliac fossa. Computed tomography showed a low-density area with rim enhancement in his right internal oblique muscle and a hyperdense 20 mm-long pointed object in the wall of the adjacent cecum. Based on the findings we suspected an abdominal wall abscess resulting from a migrating ingested fish bone. He was administered antibiotics as conservative treatment, and the abscess was not seen on subsequent computed tomography. Two months after the initial treatment, he presented with the same symptoms, and a computed tomography scan showed the foreign body in the same location as before with the same low-density area. We diagnosed the low-density area as recurrence of the abdominal wall abscess. He underwent laparoscopic surgery to remove the foreign body. His appendix, and part of his cecum and the parietal peritoneum that included the foreign body, were resected. He had an uneventful postoperative course, and at 1 year after the surgery, the abdominal wall abscess had not recurred. Conclusions An abdominal wall abscess developed in association with the migration of an ingested fish bone. We suggest that a laparoscopic surgical resection of the portion of the bowel that includes the foreign body is a useful option for selected cases.

✓ Case histories of 61 patients receiving multimodality therapy for primary malignant brain tumors were reviewed for factors visible on the computerized tomography (CT) scan that correlated with the interval of time from diagnosis and pretherapy evaluation to the time of documented tumor progression. The initial pretreatment CT scan of each patient was reviewed. Midline shift, peritumor low density (edema), the greatest diameter of tumor enhancement, and the greatest diameter of the intratumor low-density area were measured prior to radiation therapy and chemotherapy. Using a Weibull survival probability model, time to tumor progression was most satisfactorily fitted using two covariates, the volume of enhancing tumor (for instance, contrast-enhancing tumor less intratumor low density), and the presence of a peritumor low-density area. Patients who exhibited a small amount of contrast-enhancing tumor with peritumor low density tended to have a longer time to progression than patients with large contrast-enhancing tumor volume and no peritumor low density. Midline shift was not as important a variable as the extent of tumor contrast enhancement or peritumor low density.

Abstract It is well known that moyamoya disease sometimes is accompanied by cerebral aneurysm; however, no case of moyamoya disease with arteriovenous malformation has previously been published. We report such a case. A 33-year-old man suffered from transient left motor weakness and visual disturbance. Plain computed tomography (CT) showed a low density area in the left parietooccipital cortex. Enhanced CT revealed a ribbon-shaped enhanced area in the right temporooccipital cortex and a spotty enhanced area in the right frontal subcortex. Cerebral angiography revealed moyamoya disease. On the basis of Suzuki's angiographic classification, the patient was diagnosed as Stage III. Right carotid angiography revealed an arteriovenous malformation fed by basal moyamoya vessels and draining to the vein of Trolard and the sylvian vein of the right frontal lobe. This arteriovenous malformation consisted of feeders, the nidus, and drainers. Trolard's vein, which was one of the draining veins of the arteriovenous malformation, flowed to the moyamoya vessels of the right parietal vault.
