Spontaneous regression of hepatocellular carcinoma (HCC) is rare. We found spontaneous regression of HCC in a 53-year-old Chinese with liver cirrhosis. A liver mass 3 cm in diameter was revealed by B-ultrasonography. The resected mass showed histologically complete necrosis. The necrotic tissue was filled with large debris from a neoplastic tissue,(More)
A 66-year-old male with unbearable pruritus and jaundice was admitted for detailed examination. Blood tests on admission showed increased bilirubin with a dominant direct fraction. Ultrasonography and computed tomography performed subsequent to admission showed no narrowing or distension of the bile ducts. As the jaundice symptoms were not improved by the(More)
A 63-year-old woman was admitted to hospital with pain in the right lower quadrant. Abdominal computed tomography (CT) revealed a 60-mm cystic mass at a site corresponding to the appendix. The mass wall on the appendicular ostium was thickened and enhanced by contrast, while calcifi-cation was observed in the mass wall on the appendicular tip. No projection(More)
A 39-year-old male without contributory medical history had sustained progressive double vision, ptosis, and trigeminal pain for 2 weeks. Physical examination revealed total ophthalmoplegia and visual field defect with normal blood examination and chest radiography.

BACKGROUND Mucoepidermoid carcinoma (MEC) is a rare tumor of the lung that accounts for 0.1-0.2% of all pulmonary tumors. To the best of our knowledge, brain metastasis from lung MEC is rare and magnetic resonance imaging (MRI) findings of this lesion have not been documented. CASE DESCRIPTION We herein report the case of a 72-year-old male. MRI revealed(More)
We experienced a case with a synovial cyst accompanied by asymptomatic lumbar vertebral fracture that required differentiation from spinal metastasis. An 82-year-old man suffered from right leg and anal pain. Computed tomography (CT) showed L5 spondylolysis. Magnetic resonance images (MRI) revealed an intra spinal cyst and acute lumbar vertebral fracture of(More)
