היישום הרב והזמינות של בדיקות דימות בלתי-פולשניות כמו טומוגרפיה מחשבית (ט"מ), תהודה מגנטית (ת"מ) ועל-שמע העלו את תדירות איבחון הנגעים בטוחה (adrenal), נוכחות גוש בטוחה, ללא רקע של ממאירות, מהווה אתגר איבחוני כשלעצמו, בייחוד כשידועה אנאמזה של ממאירות.

מימצא אקראי של שאת בטוחה (incidentaloma) מחייב המשך בירור ומעקב ובמצבים מסוימים, גם כריתה בניתוח. במספר עבודות נמצא, כי ב-3%-0.3% מבדיקות ט"מ של הבטן העליונה מאובחן נגע בטוחה. עבודות אלו נערכו ברובן בשנים הראשונות בהן הוכנסו לשימוש מכשירי הט"מ, עקב השיפור הטכנולוגי שחל עם השנים ניתן לצפות, כי שכיחות שאתות בטוחה כיום קרובה יותר לזאת המדווחת מעבודות שנערכו בנתיחות שלאחר המוות, בהן דווח על שיעור נגעים בטוחה שנע בין 1.45% ל-5.9%, רובם טבים.

Infectious Mononucleosis in Adults - A Diagnostic Challenge

The adult form of mononucleosis caused by Ebstein-Barr virus (EBV) is different from the disease in children and adolescents. In most adults there is no pharyngitis or lymphadenopathy, fever is much more prolonged, abnormal liver function is frequent and lymphocytosis and the presence of atypical lymphocytes are not common. Such an atypical disease presentation often results in delayed diagnosis and unnecessary treatments. We describe 2 adults with such atypical presentations and complications of EBV infection.

Multilocular Cystic Mass of the Kidney: A Diagnostic Challenge

Multilocular cystic masses of the kidney present a diagnostic challenge because they may be malignant. Renal cell carcinoma with multilocular cysts has been reported. We present 4 cases in which the preoperative differential diagnosis was between a benign and a malignant multilocular cystic kidney mass.

Our results, combined with those of 33 previously reported cases, reveal that only 32% of cases were diagnosed correctly preoperatively. In 21% of these patients the preoperative clinical evaluation did not correctly diagnose malignancy: 24% of them yielded false negative and 21% false positive results. Angiography was more accurate than CT, US or aspiration of cysts. Frozen section was inaccurate in 55% of cases.

There is no reliable diagnostic test to distinguish between a malignant and a benign multilocular cystic mass. Invasive angiography is more accurate than other modalities. A therapeutic decision has to be made between nephron-sparing and radical surgery in each case. When nephron-sparing surgery is considered, the possible need to perform radical nephrectomy in second-look surgery must be taken into account.

Mass lesions in the iliopsoas compartment (MLIPC) are uncommon in patients in departments of medicine and their incidence and etiologies are unclear. In a prospective study we diagnosed various MLIPCs in 7 patients during a 10-year period, representing 0.03% of admissions. Symptoms included abdominal or flank pain (4 cases), pain along the thigh (5), diminished psoas muscle strength (2), fever (2), and hypotension (1). MLIPC was suspected on clinical grounds in 5 cases. In all cases the diagnosis was established by computed tomography (CT). Tissue was sampled by needle biopsy in 4 and on surgery in 1. MLIPCs were caused by hemorrhage (2), infection (2), neoplasia (2) and inflammatory mass (1). Often MLIPCs are life-threatening so their timely diagnosis by early CT scan is important.

Multiple Angiodysplastic Lesions of the Colon - a Therapeutic Challenge

Colonic angiodysplasia is one of the most frequent causes of recurrent lower gastrointestinal tract bleeding, mainly in the elderly. In 50% of patients multiple angiodysplastic lesions were reported when they were the cause of rectal bleeding. Bleeding from angiodysplasia is more severe and less responsive to treatment in those with coagulation disorders. A 74-year-old woman with an artificial mitral valve who was treated with coumadine is reported. A few years after operation she began to develop severe recurrent rectal bleeding because of multiple angiodysplastic lesions along the right colon, proven by colonoscopy. She was frequently hospitalized for blood transfusions; endoscopic treatment was not feasible and the surgical risk of colectomy was very high. Treatwith estrogen and progesterone significantly decreased recurrent episodes of bleeding.

Incomplete Penile Amputation: Diagnostic and Therapeutic Challenge

Traumatic penile amputation is a severe injury associated with a potential for multidisciplinary dysfunction. Since such injuries are rare, diagnostic and therapeutic experience is minimal. While complete penile amputation is a straight-forward diagnosis, incomplete amputations are not as evident and diagnosis may be delayed. The therapeutic endpoint includes restoration of an acceptable appearance of the phallus and a urethral meatus that allows normal voiding. Other objectives include re-establishment of sexual potency and fertility. As in other amputations, the treatment of choice is meticulous microsurgical replantation, including re-anastomosis of dorsal and cavernosal arteries, the deep dorsal vein, the urethra and nerves, as well as suturing the tunica albuginea. While appropriate cosmetic results and normal voiding can be achieved in most cases, potency is less frequently achieved due to neurological deficit leading to impaired erection and loss of sensation. Penile amputation is thus a complex therapeutic challenge, as meticulous anatomic reconstruction of blood vessels and nerves is essential for restoration of function. Since incomplete penile amputation may be overlooked when other more obvious injuries draw attention, this injury should be suspected in all cases of penetrating injury of the male genitalia. We present a 17-year-old man who sustained an incomplete penile amputation in a traffic accident.
