Idiopathic granulomatous mastitis is a rare chronic benign inflammatory mastopathy occurring mainly in young women. With a non-specific imagery, it is considered as a diagnosis by exclusion and has a challenging treatment. Histologically, it is characterized by the predominance of polynuclear neutrophils and the absence of caseous necrosis. The breast carcinoma is the main differential diagnosis at the clinical stage, and imagery plays an essential role in its diagnostic approach. Its treatment combines antibiotics, anti-inflammatories, corticosteroid therapy, and surgery. We report a 42-year-old woman who presented a breast lesion diagnosis as granulomatous mastitis based on magnetic resonance imaging, ultrasound, and histology examinations. She received a treatment with different drugs (antibiotics, anti-inflammatories). The outcome treatment was successful with a good healing of breast lesions.

Acute intestinal intussusception remains a surgical emergency in infants and young children aged 3 months to 3 years. It results from the incarceration of the upstream intestinal segment in the downstream segment. In the majority of cases it is idiopathic, but can be secondary to certain pathologies notably Meckel’s diverticulum. The site is most often ileo cecal. The symptomatological triad is made up of pain, vomiting, and rectal bleeding. The diagnosis is confirmed by imaging, dominated by ultrasound which remains the reference imaging. We report the case of a 3 year-old boy, followed for a malformation who presented with abdominal distension, abdominal pain, and rectal bleeding. The diagnosis of acute ileo-ileal intussusception was made. After an attempt at hydrostatic reduction under ultrasound guidance, he underwent surgical management. The postoperative period was simple and uncomplicated. Intestinal intussusception remains a pathology with a low morbidity and mortality rate of 0% to 1% due to delayed diagnosis and delayed therapeutic management.

Muscle metastases remain rare as a secondary localization for cancers in general and lung cancer in particular. They are discovered incidentally in most cases and in the advanced stages of cancer. We report the case of a 60-year-old man, followed for squamous cell carcinoma, who was found to have muscle metastases during the follow-up of associated muscle pain. This case highlights the existence of these metastases in lung squamous cell carcinoma, rare as it is, and requires particular attention from practitioners in the follow-up of patients to detect these cases as early as possible and improve patient survival. Computed Tomography (CT) remains an excellent exam for the detection of skeletal metastasis.

Pneumocystis jiroveci pneumonia is a common pathology in HIV-infected but also in uninfected immunocompromised individuals. 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. Chest computed tomography scan is gold standard imaging and shows a central and diffuse distribution, ground- glass pattern with septal thickening with “crazy paving pattern.” We reported a case of 57-year-old man patient, followed in oncology for laryngeal cancer who presented of Pneumocystis jiroveci pneumonia during his follow-up. The diagnosis is confirmed by polymerase chain reaction with bronchoalveolar lavage fluid. Other immunochemical tests can be performed but are less specific. Both curative and preventive treatment in subjects at risk remains trimethoprim-sulfamethoxazole. Corticosteroid therapy may be associated depending on the case.

Metastases to the pancreas are rare in general and scares in cases of lungs primary lesion. They are discovered incidentally in most cases. Data on their incidence, diagnosis, prognosis and management remain insufficient. The discovery is usually made at an advanced stage of lung cancer with the presence of metastases to other organs. We reported the case of a patient undergoing oncology follow-up for lung adenocarcinoma with discovery of adrenal gland metastases and a solitary pancreatic metastatic mass. His management remains palliative chemotherapy. Surgical treatment is not yet codified in these cases and remains at the discretion of the multidisciplinary oncology teams.
