Reduction en masse of inguinal hernia is an extremely rare complication arising from manual reduction of a hernia. The hernial content remaining in the hernia sac returns above the inguinal canal but remains in the abdominal wall. Accurate preoperative diagnosis of reduction en masse of inguinal hernia is challenging because the hernia appears to be reduced upon physical examination. We experienced two cases of reduction en masse. In both cases, multidetector row computed tomography revealed a closed loop obstruction near the inguinal fossa. In addition, we observed a continuous tract of the hernia sac to the inguinal canal and prominent peritoneal thickening suggestive of the hernia sac. [ABSTRACT FROM AUTHOR]

We report a case of proton magnetic resonance spectroscopy (MRS) of hemangioblastoma in a 56-yearold man with a history of hyperlipidemia who was suffering from an equilibrium disorder. Proton MRS revealed a high mobile lipids (Lip) peak between 0.9 and 1.4 ppm, which was compatible with histologically proven lipids in the tumor. No lactate peak was recognized. The creatine/phosphocreatine peak was low. Choline-containing compounds were increased. The N-acetylaspartate peak was absent, which indicated that the tumor is of nonneurogenic origin. Combined with the absence of the necrotic component on magnetic resonance imaging, this Lip peak on proton MRS could be the characteristic pattern of hemangioblastoma. These unique results of proton MRS can play an important role in the differential diagnosis of intracranial hemangioblastoma. However, further investigations are required to establish the typical characteristics of proton MRS of hemangioblastoma. [ABSTRACT FROM AUTHOR]
