Genital tract infections with ureaplasma urealyticum (UU) and chlamydia trachomatis (CT) are the most frequent sexually-transmitted disease worldwide. UU and CT infections are considered to be the leading cause for infertility and adverse pregnancy outcomes. However, little is known about the specific effect of cervical UU and CT infections on the etiology of female infertility, as well as the pregnancy outcomes of the patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET)...

A 54-year-old woman with suspicion of neuroendocrine tumor (NET) was referred for 68Ga-DOTATATE positron emission tomography/computed tomography (CT) imaging due to clinical findings. A well-defined osteolytic lesion on the corpus of the third lumbar vertebra was evident on CT images with mild uptake of 68Ga-DOTATATE, which led to suspicion of NET metastasis. Histopathologic examination revealed solitary plasmacytoma of the bone. The patient received local external radiotherapy for plasmacytoma. This case indicatesthat other diseases expressing somatostatin receptors may be inaccurately reported as tumor recurrence and highlights the importance of meticulous evaluation of positive findings...

History and clinical findings: We present the case of a 63-year-old male patient free of complaints with oncological follow up examination after renal cell carcinoma (RCC) who presented extent air in the intestinal wall. Investigations and diagnosis: The computed tomography showed a pronounced pneumatosis intestinalis with punctum maximum in the part of left and less right colon flexure. Free air as a sign of perforation was not found. Treatment and course: Retrospectively, the pneumatosis intestinalis was found in fluctuating extent in several preliminary CT and MRI investigations...

BACKGROUND: Using flat-detector CT (FD-CT) for stroke imaging has the advantage that both diagnostic imaging and endovascular therapy can be performed directly within the Angio Suite without any patient transfer and time delay. Thus, stroke management could be speeded up significantly, and patient outcome might be improved. But as precondition for using FD-CT as primary imaging modality, a reliable exclusion of intracranial hemorrhage (ICH) has to be possible. This study aimed to investigate whether optimized native FD-CT, using a newly implemented reconstruction algorithm, may reliably detect ICH in stroke patients...

BACKGROUND: For patients with lung metastases of differentiated thyroid carcinoma (DTC), there is no consensus on the maximal size of metastatic lesions to use when determining the intensity of follow-up and additional therapeutic options. We evaluated the clinical outcomes and survival of patients with metastatic DTC confined to the lung, using the maximal diameter of lung lesions in the initial computed tomography (CT). METHODS: This retrospective cohort study included 112 DTC patients with metastases confined to the lung...

Based on the histopathologic origin, malignant maxillary neoplasms may share some clinical characteristics but have different biological behavior, treatments, and prognoses. The aim of the present study was to explore the association between CT characteristics and tissue origin of primary maxillary cancer (MC). A retrospective review of CT findings was performed in patients diagnosed with MC between January 1, 2005 and December 31, 2013. Univariate and multivariable logistic regression analyses were performed to determine the association between tissue of origin and CT characteristics, with adjustment for possible confounding factors...

We report a case of a benign liver hemangioma with intense prostate-specific membrane antigen (PSMA) uptake on Ga PET/CT. A 77-year-old man with prostate adenocarcinoma underwent routine staging with PSMA PET/CT. This revealed an intensely PSMA-avid liver lesion. The known prostate adenocarcinoma was localized and had mild uptake. Diagnostic CT and MRI were characteristic of a hemangioma without interval growth over a 3-month period. PSMA PET/CT is becoming increasingly popular for staging in prostate cancer, and the presence of PSMA uptake in extra-prostatic tumors is being increasingly documented...

To determine whether pretransplant PSD affects the clinical outcomes in HSCT, a retrospective cohort analysis of 73 pediatric and adolescent patients who underwent HSCT was performed. Pretransplant PSD was defined as the presence of a fluid level or mucosal swelling or total opacity on sinus X-ray or CT examination performed before HSCT. Pretransplant PSD was observed in 21 (29%) patients. The probability of 2-year OS after HSCT was 42% in patients with pretransplant PSD (PSD group), and 64% in those without (non-PSD group) (P=...
