Synovialosarcoma is a mesenchymal tumor with soft tissue predilection, metastasizing to various organs, including the lung. Primary pulmonary involvement is rare and requires histological examination for confirmation. In early stages, the treatment is surgical followed by radiotherapy to avoid recurrence, while there's no consensus in chemotherapy.

Dissemination of clear cell renal carcinoma to the rectum is very rare, with only a few sporadic cases published in the literature. The clinical presentation is usually dominated by lower gastrointestinal haemorrhage.

However, it can also develop as a primary cutaneous adenoid cystic carcinoma, which appears identical under the microscope to adenoid cystic carcinoma originating in other tissues. Distinguishing between primary cutaneous adenoid cystic carcinoma and extracutaneous adenoid cystic carcinoma with cutaneous metastases is crucial for determining the prognosis and appropriate management of the condition.

The absence of proper testing for this type of breast cancer carcinoma exacerbates this paucity. Additionally, only scant evidence of these tumors is present because of the repeated revisions in their diagnostic criteria throughout time.

We report 2 cases of omental infarction diagnosed at computed tomography (CT) scan performed as part of routine oncological surveillance, one right-sided and the other left sided. This paper illustrates the range of CT scan findings and highlights the important clinical implications of this radiological diagnosis.

Less commonly, these benign tumors may also occur in soft tissues located outside of the breast, in which case they are referred to as mammary-type myofibroblastomas. The histologic composition of this benign spindle cell tumor can be markedly varied.

Patients with this syndrome have a high relative risk of developing cancers at a young age, led by colorectal cancer (CRC) and endometrial cancer in females. The diagnosis is suspected when the patient's personal and family history meets the Amsterdam or Bethesda criteria.

We present a case of a 62-year-old woman, and subsequently discuss the clinical and imaging presentation of mucoceles. Findings on CT scan suggested 2 diagnoses: appendiceal mucocele with pseudomyxoma peritonei and malignant ovarian tumor with peritoneal carcinosis.

The pandemic coronavirus disease 2019 (COVID-2019) is a new type of coronavirus disease caused by SARS-COV-2, and the chest imaging is often used as complementary tool in patients' evaluation. The imaging finding is similar with many pulmonary pathologies.

We report a case of a 48-year-old female presenting with a large hepatic mass that was diagnosed as a hepatic abscess, but the ultrasound-guided biopsy showed well-differentiated grade 1 neuroendocrine tumour.

Peritoneal carcinomatosis is a known metastatic site for many malignancies and particularly gastrointestinal tract and ovarian cancers. Also, DMPM can masquerade as an ovarian epithelial neoplasm, with very similar clinical presentation and an overlap in imaging findings.

The present study aimed to describe a rare case of an endocrine tumor of the stomach revealed by a splenic metastasis. We report a rare case of a 40 -year-old who presented a pain in her left hypochondriac, associated to sensation of heaviness.

The diagnosis is late with a poor prognosis. Imaging through Bili MRI and CT scan plays an essential role in the classification and staging of tumors for therapeutic management.
