Primary adenoid cystic carcinoma of the rib with metastases: A rare case report and literature review.

Adenoid cystic carcinoma (ACC) is a rare and aggressive malignant tumour predominantly found in the salivary glands but can also occur elsewhere. Primary ACC in the bones is particularly rare, with most reports focusing on cases of ACC in the maxilla and mandible. This report presents a case of ACC in a 47-year-old man with a primary origin in the right rib region, a previously unreported location.

A case of death of patient with ovarian fibroma combined with Meigs Syndrome and literature review.

Ovarian fibroma is the most common benign pure stromal tumor. It has no specific clinical manifestation, most of which are pelvic or adnexal masses. 10-15% of cases with hydrothorax or ascites, after tumor resection, hydrothorax and ascites disappear, known as Meigs Syndrome.

Correlation study between flash dual source CT perfusion imaging and regional lymph node metastasis of non-small cell lung cancer.

Background: To explore the correlation of flash dual source computed tomography perfusion imaging (CTPI) and regional lymph node metastasis of non-small cell lung cancer (NSCLC), and to evaluate the value of CT perfusion parameters in predicting regional lymph node metastasis of NSCLC.

Methods: 120 consecutive patients with NSCLC confirmed by postoperative histopathology were underwent flash dual source CT perfusion imaging in pre-operation. The CT perfusion parameters of NSCLC, such as blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability (PMB) were obtained by the image post-processing.

Correlation study between dual source CT perfusion imaging and the microvascular composition of solitary pulmonary nodules.

Objective: To explore the correlation between dual source computed tomography perfusion imaging (CTPI) and microvascular parameters, and evaluate the value of CTPI in the differential diagnosis of solitary pulmonary nodule (SPN).

Methods: 65 consecutive patients with SPN who successfully underwent pre-operative CT perfusion imaging with dual source CT and received a final diagnosis by postoperative pathology. The cases were divided into malignant, benign and inflammatory groups according to the pathological results.
