Breast metastasis in a young pregnant woman affected by metastatic melanoma.

Metastasis to the breast from extramammary tumors are rare, and the most common cancer that metastasizes to this site is malignant melanoma (MM). Unfortunately, metastases from malignant melanoma reveal a widespread of the disease and a high likeliness of poor diagnosis. In this study, a case of left breast metastasis of MM in a young pregnant woman, with a fast progression of the mammary and systemic course of pathology and unfortunately poor prognosis is presented.

Magnetic Resonance Imaging in Autism Spectrum Disorders: clinical and neuroradiological phenotypes.

Background And Aim: Autism Spectrum Disorders (ASDs) are a group of neurodevelopmental disorders that can severely compromise social and cognitive functions in childhood. Magnetic Resonance Imaging (MRI) currently represents the gold standard as an in vivo and non-invasive study of the human brain morphology. This work aims to search for possible links between clinical phenotypes and radiological anomalies that may be relevant and pathognomonic in the subsequent diagnosis of ASDs.

Castleman disease: a rare case in a young woman.

Castleman disease is a rare lymphoproliferative disorder characterized by benign enlargement of lymph nodes. It is divided into unicentric disease, which involves a single enlarged lymph node, and multicentric disease, which affects multiple lymph node stations. In this report, we describe a rare case of a 28-year-old female patient with an unicentric Castleman disease.

Extragonadal germ cell tumor: A rare case in dorsal region.

Extragonadal germ cell tumors (GCTs) are a rare group of neoplasms that account for 1%-5% of all GCTs. These tumors can present with an unpredictable behavior and clinical manifestations depending on different factors such as histological subtype, anatomical site, and clinical stage. We report the case of a 43-year-old male patient with a primitive extragonadal seminoma located in the paravertebral dorsal region, an extremely rare site.

Two rare cases of pituitary apoplexy in adult females: a tricky diagnosis.

We reported two cases of women who suffered from a rare case of pituitary apoplexy, rare and potentially fatal clinical condition due to a hemorrhagic infarction of the pituitary gland due to a pre-existing macroadenoma. The onset of symptoms is often insidious and includes generic symptoms such as headache, vomiting, and visual disturbances. In this case report we discuss the typical CT and MRI imaging features of this rare clinical condition in order to help radiologists in the timely diagnosis for a more rapid and correct diagnostic framing.

Lumbar malignant peripheral nerve sheath tumor: a rare case in a young patient.

Malignant peripheral nerve sheath tumor (MPNST) is a rare soft tissue sarcoma that originate from peripheral nerves or from cells associated with the nerve sheath. We report the case of a 30‑year‑old male patient with a history of neurofibromatosis type I (NF-1) and a MPNST located in the lumbar region. The mass was resecated but surgical margins weren't clear.

Cor triatriatum dexter: a rare incidentaloma.

Cor triatriatum dexter (CTD) is an extremely rare finding resulting from the persistence of the right valve of sinus venosus. It is a congenital cardiac anomaly defined by an abnormal septation of the atrium leading to inflow obstruction to the respective ventricle. Multimodal diagnostic modalities are necessary to characterize it for an optimal patient management.

Wunderlich syndrome: a rare case in a young woman.

We report the case of a 29-year-old woman with Wunderlich syndrome, a rare spontaneous renal hemorrhage into the subcapsular and perinephric space. She presented to our emergency department with a sudden and persistent right flank pain in the abscence of abdominal injury. The onset of the symptoms can be insidious and lead to hypovolemic shock.

Phosphaturic mesenchymal tumors: radiological aspects and suggested imaging pathway.

Phosphaturic mesenchymal tumors (PMTs) are rare mesenchymal neoplasms of soft tissue or bone origin that can give rise to a challenge in diagnostic imaging. These tumors are frequently associated with tumor-induced osteomalacia, also called oncogenic osteomalacia, which is a rare paraneoplastic syndrome characterized by ectopic secretion of fibroblast growth factor 23, a hormone that regulates serum phosphate level. PMTs show polymorphic features on both radiological findings and histological examination, causing problems in diagnosis owing to their similarity with other mesenchymal tumors.
