Case History: 37-year-old female with headaches.
Case History: We report the case of a rare lipoma in the quadrigeminal cistern in a 37-year-old female presenting with headache. She was referred to our diagnostic center by a local physician. Neurological and systemic examination were normal.
Blood analysis was within normal limits and EEG did not show abnormal discharges. Cranial NECT revealed a mass (10 x 7 mm in size) in the quadrigeminal plate cistern which had very sharply demarcated homogeneous low fatty density indicative of a lipoma (Figure 1).

Figure 1. Axial, coronal and sagittal NECT image shows a small well-defined ovoid hypodense lesion having fat attenuation (- 74 to 96 HU) at quadrigeminal plate cistern.
Diagnosis: Quadrigeminal plate cistern lipoma/tectal plate lipoma
Discussion
Learning Points
histopathological confirmation is practically never required.

July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
