Intracranial haemorrhage possibly related to Tipranavir in an HIV-1 patient with cryptococcal meningitis.

A 55-year-old HIV-infected patient on antiretroviral treatment with Ritonavir-boosted Tipranavir as part of HAART developed intracranial haemorrhage during the acute phase of cryptococcal meningitis. CT scan and MRI confirmed the intracranial haemorrhage. Positive cryptococcal antigen and cultures of both blood and CSF confirmed the diagnosis of meningitis caused by Cryptococcus neoformans.

Primary traumatic pulmonary pseudocysts: a rare entity.

Objective: Pulmonary contusion is the usual manifestation of lung parenchymal injury after blunt chest trauma. With deceleration these parenchymal lacerations can result in cavities known as primary traumatic pulmonary pseudocysts (TPPC). We present our experience in treating this rare entity.

Paraganglioma of the cauda equina: a case presenting features of increased intracranial pressure.

Paragangliomas are benign tumors arising from the heterotopic sympathetic ganglion. They occur more often in the carotid body, glomus jugulare, mediastinum, and paraaortic region; central nervous system locations include the petrous ridge, pineal region, and sella turcica. We report the clinical and imaging features of an unusual case of paraganglioma of the cauda equina.

Posttraumatic spinal cord lesions without skeletal or discal and ligamentous abnormalities: the role of MR imaging.

The thoracic spine is different from other mobile segments of the spine because of the presence of ribs and their articulations. The rib cage makes the thoracic spine much more stable and, during trauma, provides additional strength and energy-absorbing capacity. This leads to the conclusion that severe trauma is required to damage the thoracic spine, and the skeletal injury is usually evident on radiographs.
