ADC values of cervical cancer after therapy showed significant differences compared with pretherapy values, particularly for responders.

The size of the lesion and the length of the intrapulmonary trajectory are risk factors for pneumothorax and parenchymal haemorrhage. The transfissural course of the needles is frequently related to pneumothorax and intrapulmonary haemorrhage, and the type of the needle is related to pneumothorax.

IntroductionSplenosis is a post-traumatic autotrasplantation and proliferation of splenic tissue in ectopic sites. These implants may mimic malignancy in healthy patients or peritoneal metastases in cancer patients. When a previous history of splenic injury is known, the finding of soft tissue nodules in many thoracic and abdominal locations might raise the suspicion of the benign condition of splenosis, in order to avoid unnecessary surgery or chemotherapy.Case presentationA 56-year-old man with history of persistent hematuria from bladder cancer was referred to our Institution for suspected peritoneal carcinosis. For staging purposes he underwent abdominal computed tomography and ultrasound. The integration of patient's history and imaging results led to the diagnosis of peritoneal splenosis. The patient therefore underwent regular Trans Urethral Resection of Bladder for the known malignancy; while no treatment was necessary for splenosis. Two years follow-up was negative for metastases.ConclusionSplenosis is a benign condition after traumatic splenectomy which should be taken into account in the differential diagnosis with peritoneal seeding of malignancy because its appearance may resemble malignancy.

A 70-year-old female attended to our hospital complaining of a pain in the upper abdomen for the last two months that had worsened in the last 72 hours. The pain was accompanied with bilious vomits, chills and fever (38.9°C).The laboratory tests performed were normal except for the presence of leukocytosis (16,000/mm 3 ).The abdominal ultrasound (US) showed a well-defined lobulated hyperechoic with hypoechoic foci submucosal mass in the posterior wall of the gastric antrum that measured 6.5cm x 2.5cm (fig1a), but to our surprise, on US we also found a large (7 cm) rounded, predominantly liquid with internal echogenic areas, mass in the left lobe of the liver (fig 1b). The liver lesion evidenced a "honeycomb pattern" on Contrast-Enhanced US (CEUS), with non-enhancing necrotic areas and enhancing internal septae (fig1c).On Multiphasic Multidetector computer tomography (CT) the submucosal mass in the gastric antrum had fat density and liquid collections inside (fig 1d,e). The hepatic mass was heterogeneous but predominantly hypodense and had a perilesional hypodense area which showed progressive enhancement in the following phases due to hyperemic inflammatory effects on the adjacent liver.Subsequently, the patient was referred to the Digestive Department, where an endoscopy revealed a submucosal mass in the posterolateral wall of the gastric antrum with an ulcerated area on it surface. Finally, the pathological study of the gastric mass, which was surgically resected, revealed an abscessed submucosal gastric lipoma, and the microbiological study of the hepatic abscess, which was radiologically drainaged, revealed Gemella morbillorum.Gastric lipomas comprise 2-3% of the gastric benign tumors and are composed of mature fat cells surrounded by a fibrous capsule [1,2]. They are usually located in the gastric antrum, and present as solitary intramural le Fig 1. a) and b) Ultrasound images show well-defined lobulated submucosal mass in the gastric antrum (white asterisk in a) and a rounded predominantly liquid with internal echogenic areas mass in the liver (black arrow in b); c) CEUS images of the liver lesion with a "honeycomb pattern"; axial (d) and coronal projection (e) of contrast-enhanced multiphasic multidetector computer tomography images evidence the submucosal mass in the gastric antrum with liquid collections inside (whitearrows) and the hepatic mass (m).
