Primary prostate lymphoma (PPL) is rare. This article reports a case of PPL by retrospective analysis of the clinical data and review of the literature, in an attempt to explore the diagnosis, treatment, and prognosis of this rare disease. The present case involves a male patient who came to our hospital for medical consultation of dysuria. Serum prostate-specific antigen (PSA) was not remarkable. Pelvic computed tomography (CT) scan suggested obvious enlargement of the prostate and a tumor in the prostate, but the tumor was not significantly enhanced on contrast-enhanced CT scan. Ultrasound suggested obvious enlargement of the prostate with multiple local low-density echoes and rich blood flow signals inside. Histopathology of prostate biopsy suggested prostate diffuse large B-cell lymphoma (DLBCL). The patient refused chemotherapy but agreed to receive radiotherapy. After radiotherapy, the tumor became smaller and the International Prostate Symptom Score (IPSS) score was reduced. Our experience, together with literature review, suggests that prostate puncture biopsy is an important method for the diagnosis of PPL, and imaging examination can assist the diagnosis. Radiotherapy is able to reduce the tumor volume and relieve the symptoms of urinary tract obstruction, and chemotherapy can help achieve a better therapeutic outcome.

<p class="abstract"><strong>Background:</strong> Diverse disease entities may present with mass in the maxilla and include benign conditions and malignant tumours. A detailed evaluation including preoperative imaging is essential to plan approach to management of isolated maxillary sinus lesions optimally.</p><p class="abstract"><strong>Methods:</strong> We did a retrospective chart review of 14 patients with isolated maxillary swelling and involvement of maxillary sinus who presented to the Department of ENT in a tertiary care hospital over a period of 4 years. A detailed history and examination were done and investigations including contrast enhanced CT scan of the nose and paranasal sinuses was done in all patients.  </p><p class="abstract"><strong>Results:</strong> A total of 14 patients were included in this study. 7 were male and 7 were female. The mean age of the patients was 52.6, the age group of patients varied from 6 to 77 years. In our series we had patients with benign lesions like dentigerous cyst, fibro-osseous lesions, mucocele, radicular cyst, aspergilloma, and mucormycosis. Malignant cases included Adenoid cystic carcinoma, Low grade myofibroblastic sarcoma, Diffuse B cell lymphoma and undifferentiated carcinoma. All patients were treated surgically, they underwent a combined endoscopic and Caldwell Luc approach.</p><p class="abstract"><strong>Conclusions:</strong> In patients with unilateral maxillary swelling, a systematic approach to diagnosis with preoperative contrast enhanced CT scan is essential with a high index of suspicion. Trans nasal endoscopic approach with sinus surgery is the preferred approach for these lesions, however, in cases of jaw cysts and odontogenic cysts extending laterally it can be combined with a Caldwel-Luc approach.</p>

✓ The authors review 29 cases of surgically-proven isodense subdural hematomas examined by non-contrast and contrast-enhanced computerized tomography scans. Three types of isodense collections were noted: homogeneous isodense collections, mixed-density collections, and gravitational layering within subdural collections. Contrast enhancement within the cerebral cortex, cortical vessels, and subdural membranes led to the correct diagnosis in each case. Contrast-enhanced scans are essential for the evaluation of isodense subdural hematomas.

Abstract Aim of the study to evaluate the role of PET/CT in initial diagnosis and staging of lymphoma, and to determine the predictive value of 18F-FDG PET by monitoring the early response and final response after completion of chemotherapy in patients with non-Hodgkin's lymphoma. Patient and Methods our prospective study included 25 patients with pathologically confirmed nonHodgkin Lymphoma diffuse large B cell lymphoma selected from Department of Radiology at Ain Shams University Hospital from January 2019 to March 2020. The patients included in this study performed the followings: Initial PET/CT for staging, interim PET/CT and end of the treatment PET/CT. We performed low dose non enhanced CT scan first, then a whole body PET study followed by diagnostic enhanced whole body CT scan. The whole study took approximately 20-30 minutes. Results PET/CT has greater sensitivity 100% and specificity 68.8% than CT alone for detecting sites of nodal and extra-nodal involvement and for assessment of therapeutic response in non-Hodgkin lymphoma. Conclusion PET / CT is an accurate method for evaluating tumor viability in the post-therapy setting of Non-Hodgkin lymphomas. PET / CT has a significant advantage for the diagnosis of diffusely infiltrating organs without mass lesions or contrast enhancement compared to contrast enhanced CT.

Background. CT angiogram is frequently obtained after diagnosis of ischemic colitis (IC). Aims. To investigate the vascular findings of CT angiogram as compared to contrast-enhanced CT scan and whether this modality changes the management or prognosis of IC. Methods. We conducted a retrospective analysis of patients with IC from 2007 to 2013. Results. CT angiogram was performed in 34 patients (28.81%), whereas contrast-enhanced CT scan was performed in 54 patients (45.76%). In CT angiogram group, 8 patients (23.5%) had atherosclerotic changes. Stenosis was found in 12 patients (35.3%) (9: celiac trunk, 3: SMA). Among this group, one patient underwent colectomy and another underwent angioplasty of the celiac trunk who died within 30 days. Among contrast-enhanced CT scan group, 5 patients (9.3%) had atherosclerotic changes. Stenosis was found in 5 patients (9.3%) (3: celiac trunk, 1: SMA, and 1: IMA). Among this group, 3 patients had colectomy and one died within 30 days. There was no statistical difference between both groups in all vascular findings except the stenosis which was higher in CT angiogram group (P=0.0025). Neither the need for surgery nor all-cause mortality was different between both groups. Conclusion. CT angiogram did not provide any useful findings that altered the management or the prognosis of IC.

Hepatocellular carcinoma (HCC) has become one of the leading causes of cancer death worldwide. There has been anecdotal report regarding the effectiveness of proton beam treatment for HCC. In this pre-clinical investigation, the woodchuck model of viral hepatitis infection-induced HCC was used for proton beam treatment experiment. The radiopaque fiducial markers that are biodegradable were injected around the tumor under ultrasound guidance to facilitate positioning in sequential treatments. An α cradle mode was used to ensure reproducibility of animal positioning on the treatment couch. A CT scan was performed first for contouring by a radiation oncologist. The CT data set with contours was then exported for dose planning. Three fractionations, each 750 CcGyE, were applied every other day with a Mevion S250 passive scattering proton therapy system. Multiphase contrast-enhanced CT scans were performed after the treatment and at later times for follow-ups. 3 weeks post-treatment, shrinking of the HCC nodule was detected and constituted to a partial response (30% reduction along the long axis). By week nine after treatment, the nodule disappeared during the arterial phase of multiphase contrast-enhanced CT scan. Pathological evaluation corroborated with this imaging response. A delayed, but complete imaging response to proton beam treatment applied to HCC was achieved with this unique and clinically relevant animal model of HCC.
