Magnetic Resonance Imaging of Partial Segmental Priapism (Segmental Thrombosis of Corpus Cavernosum)

Idiopathic partial thrombosis of the corpus cavernosum: Aetiology, diagnosis and treatment

“…In addition to a painful mass in the perineum, which was how the condition presented in all cases, some of the patients experienced erectile dysfunction, and a few complained about dysuria or a decrease in the calibre of the urinary stream. IPT has been associated with haematological diseases such as homocysteinaemia [1], sickle cell disease [2] and congenital spherocytosis [3], cocaine [4] and marijuana abuse [2], a prior history of priapism [2,5], (vigorous or prolonged) sexual activity [2,[4][5][6][7][8][9][10], tamsulosin [11], bicycle riding [12][13][14][15] and aeroplane flight [12]. IPT is always located in the proximal part of the CC while the distal CC remains flaccid.…”

“…A septum within the corporeal tissue was described in the text and/or evident from the images in 16 of the case reports [4][5][6][7][8][9][10]12,[14][15][16][17][18][19][20]. In the remaining 10 cases the issue was not addressed and the images of the condition were unclear with regard to a septum [1][2][3][11][12][13]21,22].…”

“…Various imaging modalities including cavernosogram, ultrasound, computed tomography (CT) and MRI have been used in the diagnosis of IPT [1][2][3][4][5][6][7][8][10][11][12][13][14][15][16][17][18][19][20][21][22]. In newer case studies a combination of ultrasound and MRI or CT has replaced the cavernosogram.…”

Partial thrombosis of the corpus cavernosum: should we dig deeper into coagulopathy disorders?

“…The definitive diagnosis of partial priapism is usually achieved with a magnetic resonance (Galvin et al, 2009); usually, T2-weighted images demonstrate a low signal intensity mass in the bulb of the corpus cavernosum and a hypointense membrane separating the lesion from the normal corporeal body. However, new imaging techniques such as contrast-enhanced ultrasound have been proposed in place of standard ultrasound or magnetic resonance because of its cost effectiveness (Sauer et al, 2014).…”

“…The condition is known to be unilateral, and its aetiology is not well known. Usually, symptoms are pain and perineal mass and magnetic resonance (MR) is needed to confirm the diagnosis (Galvin et al, 2009). In most cases, the treatment is noninvasive, and anticoagulation therapy is used.…”
