spontaneous regression of a cyst of the cavum Septemberi pellucidi

Abstract

Spontaneous regression of cysts of the cavum septi pellucidi (CSP) and cavum vergae (CV) is rare and little discussed. The authors present their case report of this phenomenon following a severe headache in a 23-year-old woman, in whom magnetic resonance imaging (MRI) had previously confirmed significant thinning of the left lateral cyst wall. We consider this finding to be a possible predisposing factor to rupture and the spontaneous regression of such cysts. In addition to the mechanism of cyst regression, the interrelated causes of their expansion and formation will be discussed.

Case Details

Disease Location

Cavum september pellucidi (csp) ventricular system

Personal Characteristics

20 -year-old woman, admitted iwht intermittent headaches and blurring of vision for 6 months, was extensively investigated for secondary amenorrhoea. No history of psychological stress, excessive physical exercise, weight loss or pregnancies. Exams were normal. Hypoganadism and an empatienty sella turcica

Clinical Characteristics

Pituitary hormones profile was normal except low values of luteinising (lh) and follicle-cell-stimulating (fsh) hormoness. Skull radiograph showed slight enlargement of the sella turcica MRI showed a dilated, fluid-filled csp--cystic space was massive, compressing lateral ventricles but no evidence of ventricular obstruction. Pituitary gland was 4 mm in height was a concave upper border, homogeneous enhancement was found with contrast medium and infundibulum was midline.

Remission Characteristics

4 years later, MRI showed the ccyst decreased in size and the was no mass effect from the cyst

Treatment & Mechanisms

Proposed Remission Mechanisms

Rupture of the cyst

Clinical Treatment

None reported

Non-Clinical Treatment
