Combined diagnostic and therapeutic imaging in the diagnosis of venous sinus thrombosis in postpartum patients.

The case of a woman on day four post partum with sensorimotor deficit of the right side and CT evidence of a left temporofrontal hemorrhagic lesion, is presented. Attending physicians requested cerebral angiography. To better evaluate the clinical justification of requested imaging procedure the patient medical history and performed CT examination were carefully revised. According to this analysis and based on a clinicoradiological methodology, the request of a cerebral angiography was considered appropriate. The examination showed several radiological signs but a definitive diagnosis could not be established. Second choice imaging procedures were analyzed and MRI completed with MR-angiography was performed. It allowed to document transverse and sigmoid sinus thrombosis. Therefore, in the diagnosis of venous sinus thrombosis, MRI combined with MR-angiography was shown to be a method of first choice while angiography plays a major role in therapy for intravascular thrombolysis.

Conventional MRI, DWI and MR-spectroscopy in the study of focal brain lesions.

A case of a patient with neurologic symptoms is reported. Baseline MRI findings were inconclusive to establish a definitive diagnosis. The worsened neurologic and neuroradiologic pattern directed towards a diagnosis of tumor. A second MRI examination and MR-spectroscopy confirmed the hypothesis based on both the diagnosis of nature of the lesion and the histological characterization of the surgical specimen. The technique of MR-spectroscopy is briefly described.

DWI and MR-spectroscopy in the differential diagnosis of focal brain lesions.

The case of a patient with a previous history of cerebral infarction, shown to be positive for a brain neoformation on control CT, is presented. Subsequent MRI for an in-depth diagnostic study was completed with DWI and MR spectroscopy to define the nature of the lesion. The differential diagnosis of the lesion is discussed. In conclusion, the major diagnostic role of combined standard MRI with DWI sequences and MR-spectroscopy in the radiologic study of focal brain lesions, is stressed.

Multiple watershed cerebral infarcts.

The case of a 63-year-old female patient affected by arterial hypertension under home therapy, with disordered consciousness and confusion, is discussed. At the emergency department of another hospital she underwent cranial CT which showed mild swelling of right cerebral hemisphere. Based on the clinical suspicion of herpes simplex encephalitis compatible with a first MRI examination of the brain, the patient was admitted to the department of infectious disease of the polyclinic to confirm the diagnosis and plan the therapeutic approach. MRI was repeated and completed with EPI-DWI sequences and PRESS spectroscopy. It did not rule out categorically the infectious/inflammatory pattern but, based on a careful evaluation of the anatomic distribution of acute lesions, the most likely diagnostic hypothesis was the presence of multiple watershed cerebral infarcts on the right side.

Unusual lesion of the thalamic pineal region: role of conventional MRI and DWI in the differential diagnosis.

The case of a 53-year-old female patient admitted to the Emergency department with symptoms from right third cranial nerve of acute onset, is presented. Cranial CT, performed in emergency, documented an intra-axial mass which required an in-depth diagnostic study with cranial MRI after contrast administration. Conventional MRI and DWI helped in correct lesion characterization and in the differential diagnosis with other brain disorders.

Primary central nervous system lymphoma: role of DWI in the differential diagnosis.

The case of a female patient admitted to the hospital for a syncopal episode characterized by mental confusion, retrograde amnesia, agnosia, lack of sphincter control and behavior disorders, is presented. Cranial CT showed a frontal bihemispheric lesion. MRI completed with DWI was then performed to better define the nature of the lesion and for an in-depth diagnostic study. The diagnostic role of conventional MRI combined with DWI and the importance of the latter in the differential diagnosis between primary central nervous system lymphoma (confirmed at histology) and glioblastoma multiforme is discussed.

A case of primary breast lymphoma.

The case of a patient with a lesion in the right breast, is discussed. Retrospective evaluation of mammography and US previously performed elsewhere were not fully helpful in the differential diagnosis between benign and malignant and MRI was necessary. Morphological and dynamic characteristics could be indicative of an expansive/infiltrating lesion of the breast and support the staging. The histological examination established the diagnosis of primary breast lymphoma.
