According to a well recognized study of Shimada et al (Gynecol Oncol 101:234-7, 2006), the incidence of ovarian metastasis in patients with cervical cancer was 0.22% for stage Ib, 0.75% for stage IIa, and 2.17% for stage IIb with squamous cell carcinoma, and 3.72%, 5.26%, and 9.85%, respectively, in adenocarcinoma.
So, you can semi-quantitatively speculate about pTNM value presented in your question.
The American Joint Committee on Cancer (AJCC) TNM classification and the International Federation of Gynecology and Obstetrics (FIGO) staging system for cervical cancer are provided below.[1, 2, 3]

Categories
Stages
TX
Primary tumor cannot be assessed
T0
No evidence of primary tumor
Tis
Carcinoma in situ (preinvasive carcinoma)
T1
I
Cervical carcinoma confined to the cervix (disregard extension to the corpus)
T1a
IA
Invasive carcinoma diagnosed only by microscopy; stromal invasion with a maximum depth of 5.0 mm measured from the base of the epithelium and a horizontal spread of 7.0 mm or less; vascular space involvement, venous or lymphatic, does not affect classification
T1a1
IA1
Measured stromal invasion ≤ 3.0 mm in depth and ≤ 7.0 mm in horizontal spread
T1a2
IA2
Measured stromal invasion > 3.0 mm and ≤ 5.0 mm with a horizontal spread ≤ 7.0 mm
T1b
IB
Clinically visible lesion confined to the cervix or microscopic lesion greater than T1a/IA2
T1b1
IB1
Clinically visible lesion ≤ 4.0 cm in greatest dimension
T1b2
IB2
Clinically visible lesion > 4.0 cm in greatest dimension
T2
II
Cervical carcinoma invades beyond uterus but not to pelvic wall or to lower third of vagina
T2a
IIA
Tumor without parametrial invasion
T2a1
IIA1
Clinically visible lesion ≤ 4.0 cm in greatest dimension
T2a2
IIA2
Clinically visible lesion > 4.0 cm in greatest dimension
T2b
IIB
Tumor with parametrial invasion
T3
III
Tumor extends to pelvic wall and/or involves lower third of vagina and/or causes hydronephrosis or nonfunctional kidney
T3a
IIIA
Tumor involves lower third of vagina, no extension to pelvic wall
T3b
IIIB
Tumor extends to pelvic wall and/or causes hydronephrosis or nonfunctional kidney
T4
IV
Tumor invades mucosa of bladder or rectum and/or extends beyond true pelvis (bullous edema is not sufficient to classify a tumor as T4)
T4a
IVA
Tumor invades mucosa of bladder or rectum (bullous edema is not sufficient to classify a tumor as T4)
T4b
IVB
Tumor extends beyond true pelvis
Regional lymph nodes (N)
NX
Regional lymph nodes cannot be assessed
N0
No regional lymph node metastasis
N1
Regional lymph node metastasis
Distant metastasis (M)
M0
No distant metastasis
M1

First it needs to determine whether it refers to endometrial or cervical cancer. If any of the cervix, although it spread by local parametral infiltration - FIGO classification is pT2b. This means that changes in the ovary were not hematogenous.
In this situation there is no direct spread. There is separate metastatic small squamous carcinoma nodule in the ovary. Parametrial tissue without direct invasion.
in T4 classification: tumor invading beyond =, true pelvis or invading rectum or bladder
in my opinion I will consider ovarian metastases is T4.
but in case of small cell carcinoma is the highly aggressive type of cervix cancer.
but if you mean small nodule of squamous cell carcinoma in the ovary, spreading through blood or lymphatic from cervix to ovary, then I will consider it T4 and treat according.
This finding is casuistry. I think that is not important how to staging, perhaps M1. You should post this event. You can view article - Naoyuki Toki, Naoki Tsukamoto, Tsunehisa Kaku et al. Microscopic ovarian metastasis of the uterine cervical cancer. Gynecologic Oncology 1991; Vol 41; Issue 1, Pages 46-51.
According to my experience with similar cases, this is a distant metastasis, and she needs radiotherapy to pelvis and para-aortic area.
Additionally, the 10 lymph nodes dissected are few. At least 20 lymph nodes are required for a radical pelvic lymphadenectomy. This circumstance reinforces the need for radiotherapy.
This case requires periodic CT scan evaluations, in particular, in para-aortic lymph nodes where tumor progression is possible due to lymphatic ovary drainage.
Any staging system not useful for patients or physician must change.
These rare cases of cervical cancer with ovarian metastases should be staged like M1. However, due to its rarity, only case reports exist. This is a great opportunity for a multi-institutional, even multinational, research to obtain many cases to evaluate evolution and surviving. With this information, TNM system must change.
How could this be classified as pT4 if there was no direct extension of cervical tumor to left adnexa? This is to be considered as haema- or lymhp-born Mts.
Oophorectomy is not a part of Radical hysterectomy. In other words ovaries can be preserved if needed and are not part of radical loco-regional extirpative procedure for ca cervix.
This is an indirect evidence that ovarian metastasis is distant metastasis for ca cervix and should be considered as IVB...
