RESUMO
Spinal arachnoid cysts (AC) are intraspinal extramedullary loculated cerebral spinal fluid collections. They are relatively uncommon lesions. Spinal AC often cause symptoms such as pain, weakness and radiculopathy. In this pictorial essay we demonstrate the main radiological features of spinal AC, as well as symptoms and complications associated with them. We also describe the main differential diagnoses.

INTRODUCTION: Pons herniation after cabergoline therapy for giant prolactinoma is a complication not documented in literature. CASE REPORT: We report a medium aged patient who developed secondary hemiparesis after 18 months of medical treatment. MRI revealed pons herniation into the clivus. There was improvement with conservative treatment. Secuencial MRIs are presented showing the tumor at the moment of the diagnosis, tumor shrinkage and pons herniation. DISCUSSION: Some studies have shown that a significant and rapid tumor shrinkage resulting from treatment with cabergoline can occur and it is thought that some complications are related with this tumor regression, as in the presented case.

Peritoneal tuberculosis (TB) is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

La tuberculosis (TBC) peritoneal es una de las formas de presentación extrapulmonar de la tuberculosis. La infección por VIH es uno de los principales factores de riesgo para esta enfermedad. El diagnóstico requiere una confirmación microbiológica o histopatológica, además de pruebas radiológicas que lo apoyen. En el diagnóstico radiológico son útiles la ecografía y la TC abdominal, los hallazgos característicos son el engrosamiento peritoneal difuso, la presencia de ascitis en cantidades variables, adenopatías y nódulos caseificantes. Presentamos 2 casos de pacientes con ascitis y engrosamiento nodular del peritoneo en las pruebas de imagen y un CA 125 elevado en las pruebas de laboratorio. En ambos casos se llegó al diagnóstico de tuberculosis peritoneal después de realizar biopsia peritoneal guiada por ecografía (AU)
