The Mullerian duct cyst (MDC) occurs due to incomplete focal regression and saccular dilatation of the paramesonephric duct. It is usually found asymptomatic in adults, but it also shows symptoms such as ejaculatory impairment, hematospermia, pelvic pain, urinary retention, and urinary tract infections. MDCs are rare in children. Transrectal ultrasonography, computed tomography, and magnetic resonance imaging are useful for diagnosis. Treatment is based on age, clinical symptoms as well as size and location of the cyst. Here, we report a case of a 19-month-old boy with an infectious MDC that presented with fever. He has improved with antibiotic treatment, not surgical resection.

OBJECTIVE: Using diffusion tensor MRI (DTI), to investigate the microstructural abnormality of corticospinal tract in the cerebral palsied children with periventricular leukomalacia on conventional MRI and to recognize the clinical usefulness of DTI. METHOD: Seven patients were studied. DTI was peformed using 1.5T MR scanner (Vision Plus, Siemens, Erlangen, Germany) and fractional anisotropies of corona radiata, posterior limbs of internal capsules, and cerebral peduncles of midbrain in both hemisphere were calculated. RESULTS: The fractional anisotropy was significantly decreased in all corona radiata, posterior limbs of internal capsules, cerebral peduncles of midbrain in six patients except one hemiplegic patient, compared with that of control group. In in the hemiplegic patient, the fractional anisotropy was reduced only in affected hemisphere. In addition, the fractional anisotropy tended to be also increased as gross motor function measure (GMFM) score was increased. CONCLUSION: We believe that DTI may be efficient in evaluating microstructural abnormality on the motor pathway of brain and helpful in providing prognosis of clinical findings in cerebral palsied children with periventricular leukomalacia.

Intussusception in premature infants is very rare. Here, we report a case of multiple intussusceptions in an extremely preterm infant, born at 23+1 weeks gestation, who underwent an explolaparotomy, for bowel perforation and misdiagnosed necrotizing enterocolitis, at 20 days of life. To our knowledge, this is the most prematurely born baby that has survived with multiple intussusceptions.

We report the case of a 73-year-old man who had prostate cancer with bone metastases. Tc-99m HDP Whole body bone scan revealed multiple areas of increased bony uptake consistent with widespread bone metastases. F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) demonstrated mild F-18 FDG uptake in the lymph nodes of neck, abdomen, and pelvis. However, abnormal F-18 FDG uptake was not seen in the skeletal system. Biopsy and immunohistochemical stains of left supraclavicular mass showed metastatic prostate adenocarcinoma. Currently, there are a few reported cases of F-18 FDG PET/CT evaluation of bone metastases in prostate cancer. We discuss the discrepancy between F-18 FDG PET/CT and bone scan in the detection of osseous metastases of prostate cancer.

We report the case of a 64-year-old man with superior vena cava (SVC) syndrome due to tumor thrombus from recurrent hepatocellular carcinoma (HCC). He presented with new onset of facial swelling for 10 days. HCC was detected ten years ago. He has undergone repeated transcatheter arterial embolization (TAE) and chemotherapy. Chest computed tomography (CT) demonstrated tumor thrombus in the SVC extending to right atrium. He underwent whole body F-18 fluorodeoxyglucose(FDG) positron emission tomography/computed tomography (PET/CT) scanning for assessing the effect of TAE in HCC. F-18 FDG PET/CT showed increased uptake in the residual liver mass indicating viable tumor. There was another intense F-18 FDG accumulation in SVC extending to right atrium to suggest tumor thrombus. This case illustrates that F-18 FDG PET/CT is useful to identification of distant metastases as well as assessment of response to therapy in long-term survival HCC patients.

We present a case of infected abdominal aortic aneurysm due to salmonella enteritidis. F-18 FDG PET/CT was performed to diagnosis and during follow-up after antibiotic treatment. Computed tomography (CT) is considered to be the best diagnostic imaging modality in infected aortic lesions. In this case, a combination of CT and FDG PET/CT provided accurate information for the diagnosis of infected abdominal aortic aneurysm. Moreover, FDG PET/CT made an important contribution to monitoring disease activity during antibiotic treatment.
