RESUMO
The purpose of this report is to describe a case of tropical calcific pancreatitis (TCP). This disease is specific to tropical regions and constitutes the main cause of chronic pancreatitis in children worldwide. It can also be observed in young adults (2nd and 3rd decade). Shortage of dietary lipids during childhood has been implicated in the development of TCP and mutation of the SPINK1 gene has been cited as a predisposing genetic factor. The underlying pathophysiology of TCP is the same as chronic calcific pancreatitis (CCP) due to alcohol abuse. The main features are a sex ratio of 1, absence of alcohol consumption, occurrence of childhood diabetes in one third of cases, low incidence of acidoketosis, and presence of macro-calcifications especially in ducts. In 10% of cases TCP is complicated by pancreatic carcinoma occurring at an early age, located mainly in the body and tail of the pancreas, and having a less favorable prognosis than primary cancer. Treatment of patients with TCP is the same as for patients with CCP due to alcohol abuse. Prevention depends on improvement of nutritional status of the population.

Hydropic degeneration of a uterine leiomyoma is common. Giant forms are uncommon. Positive diagnosis may be challenging because the differential diagnosis includes other rare uterine tumors such as leiomyosarcoma. Uterine localization, the leiomyoma volume, margins with adjacent structures are best evaluated at MRI. Final diagnosis requires gross and microscopic examination. We describe such a diagnostic challenge in a 46-year-old woman with a giant hydropic leiomyoma.

We report an uncommon presentation of plasmocytoma in an AIDS patient. AIDS is associated with an increased risk of neoplasms. The incidence of Plasma Cell tumors in HIV-positive patients is greater than in non-infected patients. Multiple factors contribute to B cell neoplasms development.

We report the case of a rare glial tumor of the conus medullaris classified as pilocytic astrocytoma in a young adult. This tumor is most commonly found in the brain. The imaging findings will be correlated with the findings at histology. The literature will also be reviewed.

Hydatid disease is the most common human disease caused by helminths, but primary skeletal involvement is uncommon. Diagnosis is usually obtained late after considerable extension, half of which concerns the spine. The dissemination mode leads to local malignancy with severe prognosis. Medical imaging is essential. Plain x-ray findings are polymorphous and nonspecific, but computed tomography and magnetic resonance imaging are particularly useful for exhaustive pretherapeutic assessment of extension and for patient follow-up.

Mycetoma remains a common pathology in tropical areas. Diagnosis, based on mycology and pathology is still frequently late and treatment often leaves severe functional disorders. Medical imaging is indispensable to evaluate disease spread to bone tissue. Plain radiograms usually show cortical erosion, defects with sclerosing margins, and bone thickening. CT is the most sensitive technique to detect bony involvement. CT and MR imaging, when available, are the most accurate techniques for determining disease extension in both bones and soft tissues.

Bone and joint localizations of treponematosis vary greatly although there are many common features. Osteal and periosteal lesions are common. We report radiographic descriptions of bone and joint treponematosis, which must not go unrecognized due to the increasing incidence of these diseases.

Submucosal hemorrhage of the ureters, are a very uncommon quoted cause of hematuria when overdosing anticoagulants. We report two cases, CT shows some very typical aspects but can also highlight, as reported formerly, another associated complication: parietal hematoma of the small bowel.

We report one case of massive inguino-scrotal bladder herniation which was responsible for an acute obstructive renal insufficiency. The different types of bladder hernias and their anatomic factors are described. The clinical-radiological findings and surgical management are discussed.

Ganglion cyst of the longitudinal posterior ligament of the spine is a rare entity, only described in 11 cases. This lesion occurs in young subjects suffering from classical lombosciatica, and has perhaps a traumatic origin. Computerized tomography and MRI provide the diagnosis.
